Abstract
Spiral CT represents a major advancement in liver imaging. Because this technology significantly reduces the total scanning time and enables the acquisition of a contiguous set of images in a single breathhold, respiratory misregistration is avoided, which improves the detection of small focal liver lesions. An even greater advantage of the increased image acquisition speed is the ability to optimize timing for contrast-enhanced imaging (Baron 1994). The more precise delivery of intravenous contrast agents allows complete studies at optimum vessel opacification. Because conventional incremental CT requires 2 min or more to scan the liver, arterial phase imaging is never achieved, which requires the ability to image the entire liver in approximately 20 s. Such timing can be critical for detection and characterization of hypervascular liver tumors.
