Abstract
Objective:To analyze the MRI manifestations of recrudescent micro hepatic cellular carcinomas(MHCC) after the treatment for hepatocellular carcinoma ( HCC ) by using retrospective study, and to improve the awareness and the early diagnostic rate of MHCC.Methods: 50 cases recrudescent MHCC(57 neoplastic foci) with pathological or clinical diagnosis were gathered. The manifestations of MRI plain scan and dynamic contrast-enhancement (DCE) were analyzed, and the changes of them in the reexaminations were compared.Results: The main MRI manifestations were as follows: The rate of neoplastic foci with high signal in DWI was 93%(53/57); the rate of neoplastic foci with high signal in T2WI was 89.5%(51/57); the rate of neoplastic foci with low signal in T1WI was also 89.5%(51/57); the rate of neoplastic foci with lipids compositions in double echo detection was 8.8%(5/57). In DCE, the rate of neoplastic foci with "arterial hypervascularity and venous or delayed phase washout" was 68.4%(39/57); and 31.6%(18/57) was with "arterial hypervascularity and venous or delayed phase late washout". All neoplastic foci of 2 groups were gradually enlarging in 2-15 months reexamination.Conclusions:At present, high field MRI might be served as the best method for detecting MHCC, and plays important role in diagnosis and reexamination of recrudescent MHCC with the treatment for HCC.关键词
