Work in progress: dynamic sequential computed tomography during arterial portography in the detection of hepatic neoplasms.

Dynamic sequential computed tomography with table incrementation during arterial portography (DSCTI-AP) of the entire liver was performed in an attempt to improve the detection of hepatic neoplasms. In 13 of 17 patients, DSCTI-AP detected more hepatic lesions than were detected by other imaging methods, including radionuclide liver scans, ultrasound, computed tomography, and hepatic angiography. In only one case, an extremely hypervascular hepatocellular carcinoma, hepatic angiography was superior to DSCTI-AP. DSCTI-AP is a simple technique that may be carried out as a part of hepatic angiography. We believe that DSCTI-AP is a sensitive and useful method for the accurate detection of hepatic neoplasms.
