Dual-Phase Liver MDCT

  • Dushyant V. Sahani

The advent of multidetector computed tomography (MDCT) scanners has provided an impetus for various changes in applications of computed tomography (CT) principles and their implementation in the design of CT protocols. The advanced MDCT scanners can produce isotropic voxel resolution, which can improve detection of subtle lesions in the organ. It thus remains the major imaging modality for detection of hepatic pathologies [1, 2, 3, 4].
