Abstract

Computed tomographic (CT) scan acquisition speed, interscan delay time, and image quality have significantly improved during the past decade. Thus CT has become a standard against which newer techniques such as magnetic resonance imaging (MRI) are validated. Comparison between CT and other modalities, however, lack validity unless the protocol foreach procedure is optimized. The authors emphasize the importance of correct CT contrast enhancement techniques in order to obtain reproducible and optimal anatomical information for defining liver tumor morphology, which will determine resectability. Three-dimensional reconstruction using contiguous volume imaging with appropriate enhancement of vessels and tumor also provides important preoperative evaluation for possible resection. Analysis of the hemodynamic status of the liver parenchyma and of the lesions within it is also possible with contrast-enhanced CT although rarely practiced. With appropriate scanning techniques, excellent anatomical and functional information is obtained simultaneously using CT, although histologic specificity often remains insufficient without biopsy.
