Abstract:
PURPOSE: To evaluate the usefulness of fast magnetic resonance (MR) sequences combined with MR arterialportography in the preoperative assessment of hepatocellular carcinoma. MATERIALS AND METHODS: Twelve patients suffering from nodular hepatocellular carcinoma complicated by liver cirrhosis underwent T2-weighted turbo spinecho and T1-weighted multisection FLASH with and without fat-suppression MR imaging during single breath-holdsession in each sequence. MR arterial portography was performed with Gd-DTPA injected through a catheter into the superior mesenteric or splenic artery during the T1-weighted FLASH sequence. The pathologic findings of surgical specimen or follow-up lipiodol CT findings were compared with the MR imaging. RESULTS: MR arterial portography depicted 17 of the 19 masses (sensitivity, 89%) and the sensitivity of non-contrast fast MR sequences was 74%(14/19). The sensitivity for combined interpretation of all the above sequences was 89% (17/19). MR arterial portography showed perfusion defects from two cysts, one hemangioma, one inflammatory mass, and innumerable tiny regenerating nodules. Static T1-and T2-weighted imaging clearly differentiated, however, benign lesions and true hepatocellular carcinoma. CONCLUSION: MR arterial portography combined with other fast MR imaging allows tissue characterization as well as high detection rate in the evaluation of hepatocellular carcinoma complicated with cirrhosis.
