5 protocols using brilliance ct 64 channel

Mandibular Reconstruction with Fibular Flap

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

To reconstruct the mandible with an autograft, two surgeries are needed, one at the defect site, the other at the donor site. Hence, accurate mandibular reconstruction with a fibular flap requires 2 CT scans, one for the mandible, the other for the fibular flap. Both CBCT (cone-beam CT) for dentistry and general spiral CT are suitable, but for spiral CT, the interval between two slices should be smaller than 1 mm to guarantee a precisely reconstructed model.
In this case, the scan was carried out on a helical CT scanner (Brilliance CT 64-channel, Philips Healthcare, Best, Netherlands) under the following conditions: 120 kV, 250 mA, 1-mm slice thickness, 0.5-mm slice interval, 0.75-s rotation time, and 512 × 512 image resolution. The images of the maxillofacial region (312 images) and the fibular region (585 images) were separately recorded on a disc in a DICOM format (Digital Imaging and Communications in Medicine) file.

CT-Guided Fabrication of Temporal Bone Prostheses

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

Imaging of the cadaver temporal bones was obtained using a standard CT protocol on a Brilliance CT 64 Channel (Philips Healthcare, Amsterdam, The Netherlands). Imaging parameters were as follows: slice thickness 0.67 mm with 0.33 mm overlap; tube rotation time 0.75 s; filter set to Detail; tube voltage 140 kVp and current 300 mAs; collumation 64 × 0.625; matrix 768; resolution set to HI; and scan field of view 200 mm. The printer for fabrication of the prostheses was a Form2 3D printer (FormLabs, Somerville, Massachusetts). The printer uses stereolithographic (SLA) technology on an optically cured resin. Print parameters were a layer thickness of 25 μm using the black photoreactive resin. Digital prosthesis design was accomplished with the Mimics Innovation Suite (Materialise, Belgium).

MDCTA Protocol for Intracranial Imaging

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

All examinations were conducted with a previously reported institutional protocol 14 (link) with a minimum dose of ionizing radiation and intravenous iodinated contrast in a Philips Brilliance 64-slice CT scanner (Brilliance CT 64 Channel, Philips Medical, Eindhoven, The Netherlands). The examinations included non-contrast computed tomography and cervical and intracranial MDCTA, which required up to 5 min.
MDCTA was performed after intravenous administration of 50 mL of nonionic iodinated contrast (Ultravist®; 300 mg I/mL) at a rate of 5 mL/s using a dual-head power injector (Bayer HealthCare LLC, Whippany, NJ, USA) with an 18-G intravenous access, which was usually located in the cubital vein. The region of interest was placed in the aortic arch to determine the self-timer of the apparatus. When the attenuation in this region reached 160 HU, acquisition of the sections from the aortic arch to the vertex of the skull was initiated. Source images of CTA (CTA-SI) were postprocessed to obtain maximum intensity projections and three-dimensional views of the intracranial and extracranial arteries.

Radiographic and CT Imaging of Canine Limbs

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

Radiographic images of distal forelimbs and hip joints were acquired using a high-frequency X-ray unit (Raffaello HF/40, ACEM s.p.a, Italy) assembled with the DR system (Carestream DRX, Carestrem Health, Milano, Italy). Neutral mediolateral and craniocaudal projections of both the radius and ulna, as well as a ventrodorsal projection of the hip joints with an abduction of femurs were obtained. Radiographic images were recorded in the DICOM format and transferred to a computer. An image processing software (OsiriX Lite—Version 11, Pixmeo SARL, 2019) was used to view the images and to perform the evaluation. Total-body computed tomography (CT) was performed under general anesthesia using a 64-slice CT scanner (Brilliance CT 64 channel Philips Medical Systems Nederland) on patients in sternal recumbency. The acquisition parameters and the filter algorithm were adjusted in accordance with the different body regions. CT images were transferred to a workstation using a commercially available DICOM image viewing software (OsiriX Lite—Version 11, Pixmeo SARL, 2019) for the evaluation. For CT of the forelimbs and hindlimbs, multiplanar reconstruction was performed to obtain transverse, sagittal, and dorsal reformatting images.

Lumbar Spine Trabecular Bone Density Measurement

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

The trabecular BMD was measured in the lumbar spine by QCT at L1, L2, and L3, using a 64-slice helical CT scanner (Brilliance CT 64 Channel; Philips Medical Systems, Best, the Netherlands) and QCT phantom (Image Analysis QCT-Bone Mineral™ Phantom; Image Analysis Inc, Columbia, KY). The patient was supine with the phantom beneath the patient, and CT imaging was performed with contiguous axial slices from L1 through L3 based on scout images. The following CT imaging parameters were utilized: 120 kV, 300 mAs, 2 mm slice thickness, and no dose modulation. At the center axial slice of each vertebral body, a region of interest (ROI) density measurement of each of the three components of the phantom was obtained. An elliptical ROI was also manually drawn within the vertebral body at the center axial slice of each included vertebral body (Figure 1). BMD for each vertebral body was subsequently derived from the calibration measurements. Data extracted from sex-specific healthy controls from Cann and colleagues [22 (link)] was then used to calculate the Z-score for each vertebral body.

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.
