A clinical hands-on workshop is a one to two-hour training program for ten to thirty participants, which focuses on a specific clinical specialty and is held by a faculty of clinical experts. It includes lectures and hands-on sessions based on Siemens' advanced workplaces. In 2020, we are planning a hands-on tutorial organized during the ESC CT scan. A computed tomography scan (usually abbreviated to CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.
The scan protocols were as follows: 120-kV scans with and without ECG-dependent dose modulation and 100-kV scans with dose modulation, each with 16- and 64-slice CT systems, respectively . For 2 scan protocols, only 30 patients were included because of the limited availability of patients studied with the respective protocol.
On the second generation DSCT, this is traditionally used for better spectral separation when operating with dual-energy CT scans and not available for single energy CT. 36,37 With the third generation DSCT this system can also be used in single energy-single source mode to optimize the X-ray spectrum in a system known as “spectral modeling
With iDose4, mAs can be reduced to 50 mAs in multislice low-dose CT scan to reduce the radiation dose with minimal effect on image quality for slice thickness 4 mm. However, noise would dominate
The minimal technical requirements for TAVI CT are the following 2: 64-slice scanner. detector element width ≤0.625 mm. option of cardiac CT and ECG-gated triggering. Patient preparation. patients should take their cardiac medications as usual. no food 3-4 hours before the scan. no caffeine for 12 hours. instructions on how to breathe

ROI in the aorta at the level of the hepatic artery on the wo images. This page is for Physicians, Inside and outside this institution, and CT Technologists. It outlines CT protocols for diagnostic imaging currently applied to ou CT scanners. Dr. LP Riccelli works closely with OHSU CT techs in the art of creating optimal images from current
Table 1 gives an overview of the current technology of 64-slice scanners from four manufacturers in respect to number of slices, slice thickness, total detector coverage, and gantry rotation time. Diagrams of the different multislice detector configurations used in the first multislice scanners are represented in Fig. 1.
For instance, a higher slice count reduces scan time and produces a high-resolution image for some types of studies. However, higher slice counts, such as 128- to 320-slice, is overkill for the diagnostic imaging needs of most hospitals; the CT's advanced capabilities are often required only in cardiac or research institutions.
Details were obtained from approximately 90 CT examinations carried out in 128 slice CT scan of Teaching Hospital. For head CT scans, mean mAs decreased by about 47% on average from before
Purpose To investigate the coronary venous system and its relation to adjacent structures using 256-slice computed tomography (CT). Materials and Methods The study consisted of 102 patients who underwent coronary CT angiography (CTA) using 256-slice CT. For each patient, the coronary venous system and its relation to adjacent structures were evaluated. The appropriate locations and diameters
This article provides a review of the basic principles of CT within the context of the evolution of CT. Modern CT technology can be understood as a natural progression of improvements and innovations in response to both engineering problems and clinical requirements. Detailed discussions of multislice CT, CT image quality evaluation, and radiation doses in CT will be presented in upcoming

The automatic exposure control was switched off for all the scans and the CTDIvol selected was in between 7.12 and 7.37mGy. The raw data were reconstructed using the reconstruction kernels B31f, B80f and B70f, and slice thicknesses were 1.0mm and 5.0mm. Finally, the same parameters and procedures were used for the scanning of water phantom.
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 The purposes of the current study were to determine the CT dose index free-in-air (CTDIair) in 128 slice CT scanner and to evaluate the single scan dose profile (SSDP). Thermoluminescent Thus, the scanning time in 128-slice DSCT is shorter than in the 64-slice apparatus. The objective of this study was to compare CTA and coronary angiography (CAG) with regard to luminal graphic definition of calcified segments using this second-generation DSCT, specifically for patients with an Agatston score >400. For example, consider a typical thorax, abdomen, or pelvis examination. Typical slice widths range from 2 to 5 mm. With spiral CT, the same examination with the same slice thickness as axial CT can be completed with 50% greater table speed using a pitch of 1.5; this results in a 33% reduction in patient dose ( Fig. 1-7 ). The downside to this
Computed tomography (CT) is a simple and robust method for evaluating the peripheral arterial system and for diagnosing peripheral arterial disease. Advances in technology and variability in patient physiology make contrast administration challenging, however. This article will review patient preparation for CT angiography (CTA) of the lower
