CT and CT angiography - Basics

Abstract

The development of spiral computed tomography (CT) has seen the transformation from single slice to multislice scanners with 2, 4, 8, 16, 32, 40 and 64 detector rows with single or dual-source [1-9]. The most significant improvements include the increase in gantry rotation speed and consequent increase in temporal resolution, the increase in spatial resolution in the longitudinal axis, which is made possible by the
