[MR imaging during arterio-portography (MR-AP) in the detection of hepatic cancer]

Magnetic resonance imaging during arterio-portography (MR-AP) was performed in 2 patients of hepatic cancer. Low dose of meglumine gadopentetate (4 ml of a 0.5 mmol/L solution) was injected into a superior mesenteric artery during acquisition of a Turbo-FLASH sequence. An increase in liver to lesion contrast was obtained with MR-AP and it is also useful in the late phase to distinguish a flow defect lesion due to portal obstruction from the tumor.
