Abstract
MDCT scanners with subsecond gantry rotation times provide several advantages including faster scan time, increased scan range, and thinner collimation with improved z-axis resolution. Better definition of different phases of hepatic enhancement and shorter scanning times have increased the importance of scan timing and have led to re-evaluation and modification of existing CT protocols and contrast administration strategies. The newest scanners permit high-quality three-dimensional imaging of the liver and optimize MPR and three-dimensional reconstructions. MDCT technology improves the capability of CT to detect and characterize focal liver lesions and also expands its indications by allowing three-dimensional display of vascular and parenchymal structures.
