Fluoroscopy

Fluoroscopy is a diagnostic imaging technique that uses x-rays to obtain real-time moving images of the internal structures of the body.
It allows physicians to visualize and monitor various bodily functions and procedures, such as the movement of the gastrointestinal tract, the flow of blood through blood vessels, and the placement of medical devices.
Fluoroscopy is widely used in a variety of medical specialties, including radiology, cardiology, orthopedics, and surgery.
The technique provides valuable information to healthcare providers, enabling them to make more informed decisions and deliver better patient care.
PubCompare.ai's AI-driven platform can assist researchers in optimizing their fluoroscopy studies by helping them identify the best protocols from literature, preprints, and patents, while providing accurate comparisons to enhance reproducibility and accuracy.

Stereotactic Ablative Radiotherapy for Early-Stage NSCLC
The gross tumor volume was outlined on pulmonary CT windows, excluding soft tissue densities with standard uptake values (SUV) on PET less than 2 (likely to be atelectasis). No additional margin was added for possible microscopic extension. An institution appropriate error margin beyond this gross tumor volume (defined as the planning target volume) which included both set-up error and error related to motion, was limited to no more than 5 mm in the axial dimension and 10 mm in the craniocaudal dimension.
Patients received 60 Gy in 3 fractions of 20 Gy per fraction, which was prescribed to the edge of the planning target volume. Each fraction was separated by at least 40 hours (at most 8 days). The entire 3 fraction regimen was required to be completed within 14 days. Only 4 to 10 MV photon beams were allowed. For planning, no tissue density heterogeneity correction was allowed. Later analysis using proper accounting of density heterogeneity showed RTOG 0236 over-predicted the actual planning target volume dose such that the delivered dose was actually closer to 54 Gy in 3 fractions of 18 Gy11 (link).
Image guidance capable of confirming the position of the target with each treatment was required. Tumor motion related to respiration was required to be quantified using fluoroscopy or 4-dimensional (4-D) CT scans. If the motion confirmed with free breathing was greater than the maximum planning target volume expansions allowed by the protocol, a method of motion control such as abdominal compression, gating, breath holding was required.
Adequate target coverage was achieved when 95% of the planning target volume was covered by 60 Gy and when 99% of the planning target volume received at least 54 Gy. High dose conformality was controlled such that the volume of tissue outside of the planning target volume receiving a dose greater than 63 Gy must be less than 15% of the planning target volume and the target conformality index (ratio of the volume receiving 60 Gy to the planning target volume) was ≤1.2. Moderate dose conformality and gradient quality were controlled by the parameters listed in Table 1. The treatment plans also had to meet a number of contoured organ dose constraints (Table 2).

In Vivo Knee Joint Kinematics and ACL Lengths
Eight healthy male subjects (mean age, 30 ± 7 years; range, 23–41 years) were evaluated using an IRB approved protocol. All volunteers had no previous history of lower extremity injury or surgery prior to completing the test protocol.
One knee of each subject was imaged using a 3T MR scanner (Trio Tim, Siemens Medical Solutions USA, Malvern, PA) at the Center for Advanced Magnetic Resonance Development at Duke University. Coronal, sagittal, and axial images were acquired from the subjects while lying in a supine position using a double-echo steady-state sequence (DESS) and an eight-channel receive-only knee coil with a field of view of 15 × 15 cm2, a matrix of 512 × 512 pixels2, and slice thickness of 1 mm (flip angle: 25°; repetition time: 17 ms; echo time: 6 ms). From the three views of the MRI scans, outlines of the femur and tibia were segmented using solid-modeling software (Rhinoceros 4.0, Robert McNeel and Associates, Seattle, WA), as described in previous studies.2 (link),56 (link) Additionally, the attachment site of the ACL was outlined in the three planes of view. Knowing the voxel size, these outlines were then used to create 3D models of the distal femur and proximal tibia, as well as the footprints of the ACL on each. Orthogonal image sets were used to confirm the shape and position of the ACL. The ACL footprint was further divided into anteromedial (AM) and posterolateral (PL) bundles,28 (link) as described previously in the literature (Fig. 1).33 (link),38 (link) A previous validation study has shown that this methodology can locate the center of the ACL footprint to within 0.3 mm.2 (link) Based on a previous parametric study,38 (link) we expect this relatively small difference to have minimal effect on our results.
Following MRI, each subject’s knee was imaged while standing on a level platform from orthogonal directions using fluoroscopes (BV Pulsera, Philips, The Netherlands).33 (link) Each fluoroscopic image had a resolution of 1024 × 1024 pixels2. The protocol consisted of the following single-legged static knee positions (Fig. 2): full extension, 30° of flexion, and 30° of flexion with 10° of external rotation of the tibia and maximal internal rotation at the hip to simulate a valgus collapse position.36 (link),46 (link),52 (link),60 (link) For each pose, subjects were guided on how to position their knees by one investigator using a goniometer.
To create the in vivo joint model (Fig. 2), the orthogonal images were imported into the solid-modeling software in order to recreate the biplanar fluoroscopic system used during testing.1 (link),12 (link) Next, the 3D MR knee model was imported into the virtual fluoroscopic environment. Using custom-written edge detection software as a modeling aid to highlight the bone contours on the fluoroscopic images,1 (link),12 (link) the bones were moved individually in six degrees of freedom until their projections matched the bony outlines in the two orthogonal planes when viewed from the x-ray sources. Previous validation studies have shown that this approach can reproduce joint motion to within 0.1 mm and 0.3°.12 (link),15 (link)From these 3D models, knee joint kinematics and the length of the ACL and its functional bundles were measured. First, a coordinate system was drawn on each knee model.15 (link) The long axis of the tibia was determined by fitting a cylinder to the tibial shaft. Next, a mediolateral axis was drawn perpendicular to the long axis of the tibia and tangent to the posterior extremes of the tibial plateau. Finally, the anteroposterior axis was drawn orthogonal to the long and mediolateral axes of the tibia. On the femur, the long axis was determined by fitting a cylinder to the femoral shaft. The femoral coordinate system consisted of this proximodistal axis and an axis through the transepicondylar line. The kinematic measures examined by this study included flexion, internal/external rotation, and varus/valgus angle.27 (link) The transepicondylar line was used as a flexion/extension rotational axis. The internal/external rotation of the tibia was measured as the angle between the mediolateral axis of the tibia and the transepicondylar line projected on to the tibial plateau. Varus/valgus angle was measured as the change in angle between the long axis of tibia and transepicondylar line of the femur (Fig. 3). However, varus/valgus calculated this way is different from valgus measurements made by various videographic studies.11 (link),46 (link) Therefore, we used the coronal plane angle to approximate these measurements of valgus when viewed from a broad perspective outside the knee. Coronal plane angle was defined as the angle between the long axis of the femur and the long axis of the tibia projected on the tibial coronal plane (Fig. 3). ACL and bundle lengths were calculated as the distance between the area centroids of the femoral and tibial ACL attachment sites.1 (link),56 (link)Repeated measures ANOVA and Student–Newman–Keuls post hoc tests were used to detect statistically significant differences in flexion angle, as well as the lengths of the ACL and its functional bundles at each of the three knee positions. In addition, a two-way repeated measures ANOVA was used to detect differences between the coronal plane and varus/valgus angles in each knee position. Differences were considered statistically significant where p < 0.05.

Tracking Knee Kinematics with Moving Fluoroscopy
The ability of the moving fluoroscope to track the knee within the image area was assessed in 10 TKA subjects (three female and seven male, six GMK PS fixed bearing TKA and four GMK Sphere TKA (Medacta International, Switzerland), at least one year postop, good outcome, no/very low pain with a Visual Analogue Scale score <2, average age of 69.6 ± 7.9 y and average BMI of 26.4 ± 2.9 kg/m2), who participated in an on-going study on TKA kinematics [41 ]. All subjects provided written, informed consent to participate in this study, which was approved by the cantonal ethical committee of Zurich (KEK-ZH-Nr. 2015–0140).
Prior to each experiment, each subject was given sufficient time to get accustomed to the moving fluoroscope without being exposed to radiation (two to four walking trials). For each motion task (level walking, stair descent, downhill walking) a minimum of 5 gait cycles were assessed. TKA kinematics by means of fluoroscopy, whole body kinematics based on skin markers, as well as ground reaction forces, were measured simultaneously. Data processing of the fluoroscopic images included image distortion correction by a local algorithm operating on a reference grid, assessment of the projection parameters of the video fluoroscopic system (focal distance, location of the principle point in the image plane) determined by a least-squares optimization using five images of a calibration tube, as well as 2D/3D registration based on the CAD models of the implant components [6 , 11 (link), 42 (link)]. In addition, the following parameters were computed to evaluate tracking capability of the moving fluoroscope:

Multimodal Imaging Protocol for Knee Biomechanics
MR and dual orthogonal fluoroscopic imaging techniques have been described in detail in previous publications (9 (link), 25 (link), 26 (link)). In short, both the left and right knee were imaged with an MR scanner to create three-dimensional (3D) meshed models of the knees using a protocol established in our laboratory (9 (link)). To reduce the effects of load history on cartilage thickness, patients were asked to refrain from all strenuous activity such as lifting, running, stair climbing for at least four hours prior to their visit, and to remain non-weight bearing for approximately one hour prior to the MR imaging of the knee. Each patient was asked to lay supine with their knee in a relaxed, extended position while sagittal plane images were acquired with a 3.0 Tesla MR scanner (Siemens, Malvern, PA). The MR scanner was equipped with a surface coil and employed a 3D double echo water excitation sequence (field-of-view=16×16×12 cm, voxel resolution=0.31×0.31×1.00 mm, time of repetition (TR)=24 ms, time of echo (TE)=6.5 ms, and flip angle=25°). Each scan lasted for approximately twelve minutes. The images were then imported into solid modeling software (Rhinoceros, Robert McNeel and Associates, Seattle, Wa) to construct 3D surface mesh models of the tibia, fibula, femur and articulating cartilage. The meshes were assembled using a point density of 80 vertices/cm2 and triangular facets with an average aspect ratio of two.
After the MR image-based computer models were constructed, both knees of each patient were simultaneously imaged using two orthogonally placed fluoroscopes (OEC 9800; GE, Salt Lake City, UT) as the patient performed a single leg quasi-static lunge at 0°, 15°, 30°, 60°, and 90° of flexion. At each flexion angle the patient was asked to pause for five seconds while simultaneous fluoroscopic images were taken. Throughout the experiment, the lower limb being tested supported the patient’s body weight, while the other limb provided stability. The time elapsed between the MR scan and the lunge activity was approximately fifteen minutes.
Next, the fluoroscopic images were imported into solid modeling software and placed in the orthogonal planes based on the position of the fluoroscopes during the imaging of the patient. Finally, the 3D MR image–based knee model of the patient was imported into the same software, viewed from the two orthogonal directions corresponding to the orthogonal fluoroscopic setup used to acquire the images, and independently manipulated in six degrees of freedom inside the software until the projections of the model match the outlines of the fluoroscopic images. When the projections matched the outlines of the images taken during in-vivo knee flexion, the model reproduced the in-vivo position of the knee. This system has an error of less than 0.1 mm and 0.3° in measuring tibiofemoral joint translations and rotations, respectively (9 (link)). When comparing the dual fluoroscopic model matching technique with tantalum bead matching – a technique similar to Roentgen Stereophotogrammetric Analysis, the difference between the two techniques in the proximodistal direction (i.e. analogous to the measured apparent penetration) was 0.075 ± 0.13 mm (27 (link)).

Quantifying Tibiotalar Joint Kinematics using Dual-Orthogonal Fluoroscopy
Each pair of fluoroscopic images was imported into solid modeling software, where they were positioned in a 3D environment to reproduce the orthogonal orientation of the fluoroscopes during testing. Using a pixel density gradient matrix, edge detection software was used to outline the bone structures on the fluoroscopic images 12 (link). The 3D MR model of the tibia and talus was imported into this virtual dual-orthogonal fluoroscopic system. The 3D model was viewed from two directions corresponding to the location of the image source of the fluoroscopes. Then, the position of the tibial and talar models were individually manipulated in six degrees-of-freedom until their projections, as viewed from the two orthogonal directions, matched the outlines on the fluoroscopic images (Figure 1). Thus, the 3D models were used to reproduce the 3D motion of the tibiotalar joint during in vivo weight-bearing loading.
In order to quantify the motion at the tibiotalar joint, a Cartesian coordinate system was constructed for each subject based on the 3D anatomy of the tibia and talus. In order to reduce variability, the coordinate systems were created on both the intact and injured joints simultaneously. 12 (link) Because the same coordinate system was drawn on both the intact and deficient ankles, the motion of the two joints was directly compared using the same anatomic coordinate systems. First, point clouds of approximately 5,000 points were created from the 3D models of each talus and tibia. The point cloud of the deficient ankle was then aligned to the position of the intact ankle using an iterative closest point technique 12 (link), 31 (link). In this fashion, the position of the intact ankle under minimal load (approximately 10N) was defined as neutral for both ankles. Next, the coordinate axes were drawn on the 3D models. To define the proximal-distal axis, a cylinder was fit to the shaft of the tibia. The medial-lateral axis was defined by a segment connecting the most medial and lateral extremes of the tibia. Finally, the anterior-posterior axis was positioned orthogonal to these two axes. To determine the origin of the axis, the talus was visualized in the sagittal plane and a circle was fitted to the curve of the talar dome. The center of this circle served to define the origin in the sagittal plane. The medial-lateral component of the origin was defined by the geometric center of the surface area of the talar dome.
The coordinate systems were used to measure the six degrees-of-freedom kinematics of the tibiotalar joint. Measurements included anteroposterior, mediolateral, and superoinferior translations as well as internal-external rotation, dorsiflexion-plantarflexion, and inversion-eversion. These rotations were represented by an Euler angle sequence, where plantarflexion-dorsiflexion is measured about a fixed axis in the tibia, internal rotation about a fixed axis in the talus, and inversion-eversion about an axis perpendicular to the other two.

Pharmacomechanical Thrombus Fragmentation Protocol
Following popliteal access (required with the use of ultrasound guidance) or femoral access with a 10-F sheath under local anaesthesia and strict sterile techniques, RT using a ZelanteDVT catheter or a Solent catheter was performed for pharmacomechanical thrombus fragmentation, suction or aspiration. First, the RT catheter was slowly advanced through the thrombotic segment (only submerged in vessel diameter estimated > 6 mm). For patients without contraindications of thrombolysis, 3 mg of rt-PA [total injected volume of 50 ml] was intraclot injected under the Power Pulse® model. After 20 minutes of dwell time, with the pump unit active during slow catheter passages (3 mm/s to 5 mm/s), runs were performed across the thrombotic segment in a distal-to-proximal or adverse direction under fluoroscopic guidance. Each device activation run lasted at less than 20 seconds with breaks of 30 seconds between the runs to avoid arrhythmia, and the total run times were monitored and kept no more than 240 seconds.

Assessing Knee Function after Intrapatella Fracture
Patient baseline data, including sex, age, fracture side, and body mass index (BMI), were extracted from the hospital database. The operation time was defined as the time from the moment of incision to the time of incision closure. Radiation exposure was assessed by the radiation dose gathered from the C-arm fluoroscopy machine (GE Healthcare, USA) postoperatively. Full weight-bearing time was defined as the time when patients could walk without any assistive device or only with a walking stick to maintain balance postoperatively.
All patients were followed for at least 6 months. A Bostman score [15 (link)] and extension lag versus the contralateral healthy leg were employed to assess the postoperative knee function of the IPFP patients at 6 months postoperatively. A Bostman score of 28 or higher was considered excellent in regard to the functional recovery of the knee, 20–27 was considered good, and less than 20 was considered poor. The Insall–Salvati ratio [16 (link)] was assessed on the immediate postoperative radiograph. The radiograph outcomes were evaluated by anteroposterior and lateral radiographs at 1 and 3 months postoperatively.

Medial Open-Wedge High Tibial Osteotomy Technique
All surgical procedures were performed in a standardized manner under general anesthesia and performed by one of the four surgeons. No pneumatic tourniquet was used during the study period. The MOWDTO procedure performed in this study followed the triplane osteotomy technique described by Akiyama T [20 (link)]. First, transverse osteotomy was made along the guide wire inserted toward the hinge point, which was located at the upper level of the proximal tibiofibular joint and 5 mm medial from the lateral cortical margin. The osteotomy was initiated from 35 to 40 mm distal to the medial tibial joint surface. Subsequently, an arc osteotomy centered at the hinge point was performed with a radius of approximately 50 mm. To connect the arc osteotomy with the first transverse osteotomy, a descending osteotomy was made on the coronal plane starting at 15 mm posterior to the tibial tubercle and advancing distally to the level of the arc osteotomy (Fig. 1). After the triplane osteotomy was completed, the medial wedge was gradually opened while monitoring the limb alignment on fluoroscopy by checking the position of the alignment rod at the joint level. Finally, the osteotomy gap was filled with β-tricalcium phosphate (OLYMPUS, Tokyo, Japan) and fixed using a locking plate (Tris Medial HTO Plate System; OLYMPUS, Tokyo, Japan) (Fig. 2). The suction drain was placed in the subcutaneous layer.

Minimally Invasive Surgical Techniques for Lumbar Decompression
For the PTED group, the surgical procedure (based on the L4–L5 segment of DLS) was performed following methods reported in the literature [18 (link)]. The following steps were performed: (1) part of the superior articular process (SAP) of L5 was removed. A soft pillow was placed under the patients' waist, while the patient was in the lateral decubitus position with their knee and hip flexed. The incision was located 8–12 cm from the midline horizontally and 1–3 cm above the iliac on the side with leg pain. The mixed local anesthetic, which consisted of 30 mL 1:200,000 epinephrine and 20 mL 2% lidocaine, was only used in PTED group. After 5 mL of the mixed anesthetic was inserted into the skin at the entry point, 20 mL was inserted into the trajectory, 15 mL was inserted into the articular process, and 10 mL was inserted into the foramen. Then, 0.8–1.0 cm of skin and the subcutaneous fascia were incised. Drills were used to resect the ventral osteophytes on the SAP. The PTED system (Hoogland Spine Products, Germany) was inserted (Fig. 1). (2) Parts of the ipsilateral ligamentum flavum, perineural scar, and extruded lumbar disc material were completely resected with endoscopic forceps (Fig. 2). (3) The superior endplate of the L5 vertebral body was removed by endoscopic micro punches and a bone knife. Therefore, 270-degree decompression of the traversing nerve root was achieved (Fig. 3). The drainage tube was placed after hemostasis was reached.

For the MIS-TLIF group, the surgical procedure was performed in accordance with methods reported in the literature [19 (link)]. After successful general anesthesia with tracheal intubation, the patient was placed in a prone position with chest and hip pads, and the L4–L5 intervertebral space was marked with X-ray fluoroscopy. The skin and subcutaneous fascia were cut; a trans-muscular surgical corridor was created with two micro-laminectomy retractors docking on the facet joint complex. After exposing the bony structure, part of the lamina and inferior articular process of L4 and the upper L5 articular process were removed with the rongeur on the ipsilateral side, and the hypertrophic ligamentum flavum was peeled backward. If MRI showed contralateral lateral recess stenosis, then predecompression was performed on the contralateral side. After decompression on the dorsal side, the nucleus pulposus and endplate cartilage were removed with forceps. An appropriate cage (Medtronic) filled with autograft from laminectomy was placed in the center of the intervertebral space via the Kambin’s triangle area. After adequate hemostasis was achieved, two drainage tubes were placed and removed when the drainage volume was < 50 mL/d.
Postoperatively, patients was treated with oral nonsteroidal anti-inflammatory drugs and antibiotics for 3 days. All patients were encouraged to perform straight leg raising 1 day postoperatively, and moderate off-bed activity with a brace 2–3 days postoperatively. On the third postoperative day, patients were allowed to go home if their lower extremity pain symptoms were effectively relieved with no evidence of infection. The patient demographics and perioperative outcomes were compared. The VAS score, ODI, and modified Macnab criteria were used to evaluate the clinical outcomes [20 (link)].
