Evaluation of the liver using computed tomography scan

摘要

Lesions of the liver are a common clinical problem. Although ultrasonography is the first screening investigation in such patients, a computed tomography (CT) scan is often required for their evaluation. With the introduction of multi-detector row CT (MDCT), it is now possible to image larger volumes at narrower slice collimations; and image the lesions in various phases after administering a contrast medium. All these features result in improved detection and characterization of the lesion. We describe the CT appearance of a spectrum of common conditions that are encountered by a clinician, and briefly discuss these in relation to recent advances in CT technology.
