Until recently, CT scanner performance was limited by a series of compromises. With single-detector scanners, one cannot select thin collimation and still maintain the required extent of volumetric coverage. Slow scans cause motion artifacts that impair image quality. The introduction of multidetector CT technology, however, has revolutionized the field. Currently multidetector, multislice CT scanners acquire up to four channels of data from interweaving spirals. The minimum gantry rotatio...

Recent technological developments have broadened considerably the role of magnetic resonance imaging in the evaluation of liver pathology. Today, MR imaging is not looked upon merely as a problem-solving technique but is widely considered the principal imaging modality for both the detection and accurate diagnosis of focal and diffuse liver disease. Advances in hardware and sequence design and the advent of novel contrast agents with liver-specific properties have contributed towards makin...
