Abstract
Objective: To investigate the MR characteristics of small hepatocellular carcinoma (SHCC) with hepatic cirrhosis in the plain scan and dynamic enhanced scan, to compare with the blood supply, to raise diagnosis of SHCC. Methods: MR images of 48 SHCC with hepatic cirrhosis proved by clinic and pathology were reviewed retrospectively, which were performed u-sing a 1. 5 Tesla MRI unit with plain scan and dynamic contrast enhanced as well. Results: Of 48 SHCC with hepatic cirrhosis, slightly hypointense or hypointense was showed in 33 of 48 lesions on out phase T1 WI. On T2WI,34 SHCC were slightly hyper-intense or hyperintense,10 of which were slightly hyperintense or isointense on inphase T1WI, and hypointense or isointense on out-phase T1WI. 19 SHCC had pseudo capsule. The artery feeding type was 72. 8%. The portal venous supplied type was 10.4%. Normal or slightly increased type was 6. 3%. Double blood supplied type and poor supply type was 6. 3% and 4. 2% respectively. Conclusion: There are 5 patterns in dynamic enhanced MR imaging in SHCC, which indicates different blood supply, including essentially no enhancement, sustained enhancement slightly, rapid increase and rapid decrease, rapid increasing initially and decreasing slowly and slowly increasing initially and rapid decreasing, while 38(79. 2%)SHCC showed obvious enhancement during arterial phase. To combine the MR characteristics, it can provide definite basis for the early diagnosis of small hepatocellular carcinoma, differentiation may be available.关键词
