METHEDS Twenty-five patients diagnosed as hav- ing thrombus due to hepatocellular carcinoma were corroborated. MR imaging was perfomed with a 1.0T superconducting magnetic system. Both T1 and T2 weighed images and FLASH sequences were obtained in transverse plane. Additional FLASH images were ob- tained in coronal plane. RESULTS Thrombus in portal vein had a signal in- tensity similar to that of the main tumors. Intrinsic por- tal vein thrombus was in 16 patients. Six cases showed occlusive thrombus. Diffusely narrow portal branches were found in 3 patients. Portal venous thrombus showed an area of signal intensity which was replacing the normal flow void in the portal vein and showed a stumpy portal vein,irregular stenosis of portal vein and the formation of vascular net. CONCLUSION MRI was more sensitive and specific and a noninvasive method in detection of portal tumor thrombus used jointly with spin ech (SE) and gradient echo (GRE) techniques.展开更多
