Recent CT for Liver Disease: Dongil Choi; Journal of the Korean Liver Cancer Study Group. 2011;11(1):23-25. Published online February 28, 2011

Abstract PDF: The recent advance in CT is the multidetector (MD) CT scanner. MDCT increases scan coverage, and can take shorter scan time, thinner sections and longer scan range. Double arterial phase imaging could show the high sensitivity of in hepatic tumor detection. CT angiography by using MDCT is useful in a detailed assessment of hepatic arterial anatomy using a three-dimensional dataset. Dual-energy CT was more recently introduced and popularized. Dual-source CT uses two energies, 140 and 80 kVp. This technique can measure chemical composition by dual-energy index. Dual-energy CT provides the ability for CT to differentiate between different materials at imaging. The latest technologic advancements in MDCT and availability of commercial software allow perfusion CT to offer a variety of clinical and research applications. Perfusion CT imaging can be used for the characterization and treatment monitoring of hepatic malignancies.
