MDCT AN INTRODUCTION TO CLINICAL APPLICATIONS
This document provides an introduction to multi-slice CT (MSCT) and describes some of its clinical applications. MSCT allows for faster scanning, improved resolution, and the ability to acquire multiple slices simultaneously. This enables more detailed 3D imaging and angiography of various organs and body systems. Some examples given include MSCT angiography of the brain, thoracic aorta, abdomen, and lower limbs. MSCT is also used to image the liver, biliary system, kidneys, ureters, and bladder. It can detect abnormalities such as cysts, masses, stones, and fractures. In summary, MSCT provides improved imaging capabilities for evaluating many anatomical structures and pathologies.

- 2. INTRODUCTION The introduction ofspiral CT in the early 1990s resulted in fundamental and far-reaching improvement of CT imaging. For the first time volume data could be acquired without mis-registration of anatomical details, which initiated the development of 3D image processing techniques such as multi-planar reformations (MPRs), maximum intensity projections (MIPs), surface-shaded displays (SSDs) or volume renderings.
- 3. As an importantapplication CT angiography (CTA) has been established in clinical practice. As a consequence of increasing clinical demands, single-slice spiral CT with 1-s gantry rotation time soon encountered its limitations.
- 4. Larger volume coverageand improved transverse resolution can be achieved by simultaneous acquisition of more than one slice and by a shorter gantry rotation time. The first step towards multi-slice acquisition was a two-slice CT scanner introduced in 1993 (Elscint Twin). In 1998 all major CT manufacturers introduced multi-slice CT systems which brought about considerable improvements of scan speed, transverse resolution and utilization of the tube output.
