目的:探讨利用标本MR扫描进行肝细胞癌征象学研究的可行性。材料和方法:对15例手术切除的HCC标本进行MR扫描,并与术前MR检查资料作MR征象的对照分析,比较其一致性。结果:①116个瘤内均匀信号区:T_1WI稍低,T_2WI稍高信号、T_1WI等,T_2WI稍高信号、T_1WI,T_2WI均为稍高信号三组信号强度配对的相同率分别是88.7％、69.7％和100％;②112个不同形态的瘤内异常信号区:片状、条状、斑点状的相同率分别是100％、87.0％和81.0％;③106个MR上肿瘤边缘形态:边缘清楚无分叶、边缘清楚伴分叶、边缘不清的相同率分别是96.2％、56.0％和67.9％。结论:HCC术后标本MR扫描与术前MR扫描所表现的MR征象基本相同,可以用MR标本扫描来进行HCC的MR征象一病理基础对照研究。
Objective: To explore the feasibility of using MRI scanning of the specimens for the study of hepatocellular carcinoma. Materials and Methods: MR scanning was performed on 15 surgically resected specimens of HCC. MR images were compared with preoperative MR examinations to compare their consistency. Results: There were 1116 intratumoral homogeneous signal regions: slightly lower T_1WI, slightly higher signal on T_2WI, T_1WI, etc., slightly higher signal on T_2WI, T_1WI, and slightly higher signal on T_2WI. The same rate of signal intensity pairing was 88.7% and 69.7%, respectively. And 100%; 2112 different types of tumor intra-area abnormal signal areas: the same rate of flaky, strip, and spot-shaped were 100%, 87.0%, and 81.0%; 3106 MR on the edge of the tumor morphology: the edge is clear and no leaf The same rate of clear edges and unclear lobes were 96.2%, 56.0%, and 67.9%, respectively. Conclusion: MR signs of HCC specimens after MR scanning and preoperative MR scanning are basically the same. MR specimens can be used to perform HCC MR signs in a pathological control study.
