High contrast enhancement of the liver in CT by repeated doses of contrast medium.

A technique consisting of repeated injections of contrast medium has been used in 530 cases of upper abdominal CT studies for evaluation of hepatic and pancreatic disease. Out of 530 cases, 105 patients had hepatic lesions, 62 metastatic, 3 adenomas, 4 haemangiomas and 6 hepatomas. The remaining 30 patients had cystic lesions involving the liver. Using a repeat dose technique and rapid scanning, the accuracy rate ranged about 90%. Th authors feel that this technique should be employed routinely for evaluation of hepatic problems and that other techniques should be abandoned.
