Spiral CT is a technique for rapid scan acquisition. It involves conti
nuous scanning as the patient is advanced at a constant rate through t
he CT gantry. This eliminated interscan delay and the gap between scan
slices. The acquired scan is a volume dataset, resulting in improved
multidimensional displays. The entire abdomen is scanned within approx
imately 30 s, so that optimal contrast dynamics for evaluation of the
vasculature are easily obtained. High levels of parenchymal enhancemen
t are readily achieved throughout the duration of the scan. These fact
ors also contribute to the improved quality of the multidimensional di
splays. In this article, applications and clinical experience with spi
ral CT in the abdomen are reviewed.
