Magnetic Resonance Imaging for Cyclops Lesions

Check if the same lab product or an alternative is used in the 5 most similar protocols

Cyclops lesions were defined as soft tissue masses with a convex anterior border located in the intercondylar notch, characterized by varying signal intensities on intermediate-weighted images (3D FSE), as previously described^{28 (link)}. Previous studies have demonstrated a good sensitivity, specificity, and accuracy of MRI in revealing cyclops lesions (sensitivity 85.0%, specificity 84.6%, and accuracy 84.8%)^{23 (link),24 (link)}. In addition, a diameter of 5mm in each plane was used as the minimum required size to avoid false-positive cases^{23 (link),24 (link)}.
The volumes of the cyclops lesions (VCL, mm³) were measured. Similar to previous studies^{23 (link),25 (link)}, two perpendicular diameters (a_⊥, b_⊥) of the lesion were measured on the sagittal 3D FSE sequence and a third measurement (c_‖) was made on the axial reconstruction where the lesion was more conspicuous (Fig. 1). All the measurements were performed on a picture archiving and communication system (Agfa IMPAX 6, Agfa Healthcare, Mortsel, Belgium). Using the semi-axes measurements derived from the measurements described above, the VCL was approximated to be the volume of an ellipsoid:

V C L = \frac{4}{3} (π \cdot a_{⊥} \cdot b_{⊥} \cdot c_{‖})

Comparative FPCT and MDCT Phantom Scans

Check if the same lab product or an alternative is used in the 5 most similar protocols

CT examinations were performed in a mobile compact FPCT (Verity, Planmed Oy, Helsinki, Finland) and an MDCT (Aquilion One, Toshiba, Minato, Japan). Dose measurements were performed as previously published.^{4 (link)} Examinations in the FPCT were performed with default settings. Field of view (FOV) and dose settings of the MDCT were adjusted to meet the properties of its counterpart (Table 1). The FPCT performed a partial rotation of 210°, while acquiring 300 projection images. The MDCT performed a partial rotation of 180° without pitch. The same CT table was used in both devices. The synostosized 3rd and 4th metatarsal bones of all prepared phantoms were scanned. Image reconstructions were performed with default settings in each device following manufacturer's instructions. MDCT images were reconstructed using iterative technique (AIDR3), and FPCT images were calculated with a filtered back projection algorithm. Image data were sent to a picture archiving and communication system (PACS/ AGFA Impax 6, Agfa, Mortsel, Belgium).

Measuring Lumbar Spine Length: A Reliable Approach

Check if the same lab product or an alternative is used in the 5 most similar protocols

Three authors (LP, JL, TF) measured LLS and SLLS independently on the sagittal T2-weighted slice showing the midplane of the conus using the AGFA Impax 6 software (AGFA Health Care, GmbH, Bonn, Germany). For LLS measurements a straight line was drawn from the posterior-superior corner of the L1 vertebral body to the posterior-superior corner of the S1 vertebral body (Fig. 3, red line). For SLLS measurements a line was drawn from the posterior-superior corner of the L1 vertebral body to the posterior-superior corner of the L2 vertebral body. The procedure was repeated until the line reached the posterior-superior corner of the S1 vertebral body (Fig. 3, blue line). LLS and SLLS were both determined by the length of the line (mm) [15 (link)]. Inter-rater reliability for both measurements was tested previously. The estimated intraclass correlation coefficient (ICC) calculated with a two-way mixed effects model with an absolute agreement definition was .99 (95% C.I. ranging from .98 to .99) and .99 (95% C.I ranging from .97 to .99) for LLS and SLLS measurements, respectively.Fig. 3

Quantitative and Qualitative Evaluation of MDCT and FPCT in Musculoskeletal Imaging

Check if the same lab product or an alternative is used in the 5 most similar protocols

Six readers (2 radiologists with 25 and 2 years of experience in musculoskeletal radiology, 2 orthopedic surgeons with 12 and 7 years experience in musculoskeletal radiology, and 2 hand surgeons with 5 and 3 years experience in musculoskeletal radiology) performed a quantitative and qualitative image analysis. Images were evaluated in a PACS (AGFA Impax 6, Agfa, Mortsel, Belgium), viewing conditions were kept constant and the displays used (RadiForce RX220; EIZO Corp, Hakusan, Ishikawa, Japan) were calibrated according to digital imaging and communications in medicine (DICOM) part 14.¹⁰The readers were blinded to the modality of the scans. The scans were presented in a randomized order with a randomized alteration of MDCT and FPCT image series. To avoid recall bias, the equivalent images of the other modality were presented to the readers in a mirrored way in different randomized order after 8 weeks.

Radiographic Assessment of Thoracic Lesions

Check if the same lab product or an alternative is used in the 5 most similar protocols

Each calf underwent standing left to right latero‐lateral and recumbent ventro‐dorsal radiographs. A 500 mA and 150 kVp Siemens Vertix machine (Siemens, Mississauga, ON, Canada) and an AGFA DX‐S CR system, using a focused grid (grid ratio of 6:1; Reina Imaging, Crystal Lake, IL, USA), were utilized.¹⁸Radiographs were transferred to a Picture Archiving and Communication System (PACS) and viewed on a single workstation using AGFA Impax 6 (Agfa, Toronto, ON, Canada). A single American College of Veterinary Radiology (ACVR) certified diagnostic imaging specialist, unaware of the component tests and TUS results, reviewed the radiographs 10 months after enrolment of the last calf in the study. Radiographic variables used to determine if TR was considered positive (TR+) are described in Table 3. Thoracic radiographic studies exempt of any of the listed thoracic lesions were considered negative (TR−).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
