Abstract
Portal vein embolization (PVE) has been used in the preoperative treatment for major hepatectomy, and CT scan used as a useful tool for the evaluation of the hepatic volume change. In this report, we evaluated the efficacy of the Gd-EOB-DTPA MRI in 4 cases, by comparing with the results of conventional CT scan. All 4 cases underwent trans-ileocecal portal vein embolization (TIPE), and both Gd-EOB MRI and CT scan were performed after 2-4 weeks after PVE. In the hepatobiliary phase, the embolized lobe was shown as a low intensity area by CT scan; however, the Gd-EOB MRI demarcated the line between the embolized and non-embolized lobe more clearly. In addition, reduction of the excretion of contrast medium into the bile duct in the embolized lobe was remarkable, indicating that Gd-EOB-DTPA MRI could reflect no function of the embolized lobe. The present findings suggest that the Gd-EOB-DTPA MRI appears to be more useful in the evaluation of PVE than the conventional CT scan.
