Dose length product (DLP) measured in mGy*cm is a measure of CT tube radiation output/exposure. It is related to volume CT dose index (CTDIvol), but CTDI vol represents the dose through a slice of an appropriate phantom. DLP accounts for the length of radiation output along the z-axis (the long axis of the patient). DLP does not take the size –A 35-cm-long chest CT scan, acquired with a 0.5-mm slice thickness, would result in 700 images. –CT images are normally viewed with a 3-or 5-mm slice thickness, which combines six to 10 thin slices. –CT images viewed on monitors have a pixel brightness related to the average attenuation coefficient.

Technique Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g 1. Introduction: scope of the document. Cardiac computed tomography (CT) has changed rapidly since the last major guideline from SCCT. 1 While there have been significant advances in technology, the most gratifying part has been the development of a robust evidence base for the use of cardiac CT in diagnoses of heart disease, prognostication and modulating therapy (both medical and 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. The resulting maximum scan speed for 128-slice DSCT is 458 mm/s and even 737 mm/s for 192-slice DSCT. At the maximum pitch, this scan mode delivers a temporal resolution of ~rotation time/4 since no redundant data are acquired. Lowering the pitch also lowers the temporal resolution. 16 Slice CT Scan. One of the most utilized types of machines in hospitals. The running time is fast because it will only take 16 slices of images. It can be used in hospitals with too many patients waiting in line. 40 Slice CT Scan. The result of this scan is much better than the 16 slice version. It can also create faster duration of scan. 64

Overall diagnostic accuracy for the detection of graft patency was 95% for 64-slice vs 92% for 16-slice MDCT. By analyzing the 173 grafts by 64-slice vs 153 grafts by 16-slice MDCT that could be evaluated, sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV) of the MDCT for visualization of graft patency were 90, 98, 90 and 98% vs 87, 97, 94 and 93%
Computed Tomography (CT) imaging is also known as "CAT scanning" (Computed Axial Tomography). Tomography is from the Greek word "tomos" meaning "slice" or "section" and "graphia" meaning
