Multislice CT

The development of the multislice CT scanner (also known as multidetector CT or volume CT) significantly reduced scan time. As opposed to standard systems, multislice CT uses multiple detector rows. In this setting, not just one slice is scanned per rotation, but multiple slices simultaneously (fig. 6).

Single-slice versus multislice CT.

Depending on the number of detector rows, we use the term 4, 6, 8, 10, 16 or 64-slice CT (the term multidetector CT is also used regularly in the literature). Significant benefits of multislice CT include shorter scan time(with fewer movement artifacts), thinner slices and longer scan range in CT angiography tests.
