Imaging of the liver.

New developments in imaging of the liver have continued during the past year. Ultrasonography, particularly color Doppler applications, and invasive CT techniques are used with increasing frequency. New contrast agents are being tested for improved ultrasonographic detection of liver lesions, and faster imaging sequences and variations on older techniques are innovations in the field of MR imaging. Correlation studies addressed the issue of which are the best-suited imaging methods for the various pathologic changes in the liver.
