Abstract |
Twenty patients with hepatocellular carcinoma were studied by dynamic sequential inversion recovery snap shot fast low angle shot (FLASH) imaging after the bolus injection of various amounts of Gd-DTPA. We determined the optimal dose of Gd-DTPA for depicting tumors as early marked enhancement and compared the method with dynamic CT by matching data acquisition time. The optimal dose was estimated to be 0.1 mmol/kg. Compared with dynamic CT, dynamic MRI showed rapid short-term enhancement in the early phase, while the contrast enhancement in the late phase lasted longer and was stronger than that of CT.
