Patients were advised to hold their breath during the scan. Scanning parameters were: slice collimation 2 × 128 × 0.6 mm by means of a z-flying focal spot, gantry rotation time 280 ms, and tube potential 100 kV or 120 kV based on a body mass index (BMI) cutoff of 25 kg/m 2 [23, 24]. Attenuation-based tube current modulation was used with a
128 Slice. Brand. Siemens. Model Name/Number. Somatom Definition AS. Rotation Time. 0.28 sec. With The Somatom Definition As, Siemens Provides A Scanner That Is Capable Of Adapting To Virtually Every Patient And Every Clinical Question. Scalable From 20 Up To 128 Slices The System Can Be Configured To Your Specific Clinical Needs.
Methods: The scanners investigated were a newly installed Siemens Biograph mCT PET with 64-slice SOMATOM Definition AS CT using sinogram affirmed iterative reconstruction (SAFIRE) and two GE Discovery 710 PET scanners with 128-slice Optima 660 CT using adaptive statistical reconstruction (ASiR). Following exploratory phantom work, 33 adult Brilliance 16-slice: MX 16-slice: Ingenuity CT: Brilliance 64-channel: Brilliance Big Bore Oncology: IQon Spectral CT: CT 6000 iCT: Incisive CT: MX16EVO2: Access CT: Philips Brilliance Big Bore: Spectral CT 7500: IQon Elite Spectral CT: Incisive CT: Detectors, type: Solid-state GOS: Solid-state GOS: 16,128 elements: solid-state GOS: Solid-state The patient was scanned using 128 slice multi-detector CT OPTIMA 600 (GE). Procedure • Preparation of patient for scan: the patient was kept nil orally for minimum 4 hours prior to the CT to avoid complications during the administration of the contrast medium. • Risks and procedure were explained and informed consent was taken.

CT scans produce 2-dimensional images of a “slice” or section of the body, but the data can also be used to construct 3-dimensional images. A CT scan can be compared to looking at one slice of
Objective To compare the diagnostic accuracy and radiation doses of two low-dose protocols for coronary artery imaging with second-generation, dual-source CT in comparison with catheter angiography (CA). Design, setting and patients Prospective, single-centre study conducted in a referral centre enrolling 100 patients with low-to-intermediate risk and suspicion of coronary artery disease. All
Background A significant proportion of the radiation dose from a PET-CT examination is dependent on the CT protocol, which should be optimised for clinical purposes. Matching protocols on different scanners within an imaging centre is important for the consistency of image quality and dose. This paper describes our experience translating low-dose CT protocols between scanner models utilising .
