【摘要】：目的探讨高场强MRI对于肝硬化退变结节以及小肝癌诊断、见表诊断的临床应用价值。方法选择2014年1月至2016年1月期间在我院就诊的18例共24个肝硬化退变结节(DN)以及15例共26个小肝癌(SHCC)患者的MRI图像作为研究资料,对33例患者的MRI图像进行回顾性分析。结果在18例24个DN患者中,4个在同反相位T1WI上呈现等信号,比例是16.67%,其余20个呈稍高信号,比例为83.33%;在15例26个SHCC患者中,6个(23.08%)在同相位T1WI上呈稍高信号,另有20个(76.92%)在同、反相位Tl WI上呈低信号或等信号。在T2WI上DN组患者的24个结节均呈现低信号,而SHCC组的26个结节中,24个呈现不均匀等信号、稍高信号或高信号,所占比例是92.31%,仅2个在T2WI上呈现低信号,比例为7.69%。在Gd-DTPA动态增强扫描中,发现DN组中14例患者的15个DN是呈缓升速降型的,比例为93.33%,其中13个DN可发现不规则网状纤维隔强化,比例86.67%,仅1个DN呈假包膜样强化;SHCC组中14例患者24个SHCC是呈速升速降型的,比例为92.31%,其中包膜强化有17个,比例为70.83%。结论高场强的MRI能够有效的凸显肝硬化患者退变结节和早期小肝癌的相关特征,从而做出诊断和见表诊断,帮助临床提高诊断率,从而制定后续治疗方案。
[Abstract]:Objective to investigate the clinical value of high field MRI in the diagnosis of degenerative nodules of cirrhosis and small hepatocellular carcinoma (HCC). Methods from January 2014 to January 2016, MRI images of 18 patients with 24 degenerative nodules of cirrhosis and 15 patients with (SHCC) of small liver cancer were selected as the data. The MRI images of 33 patients were analyzed retrospectively. Results of the 18 patients with 24 DN, 4 showed equal signal on the ipsilateral T1WI, the proportion was 16.67 and the other 20 showed slightly higher signal intensity (83.33%). Of the 15 patients with 26 SHCC, 6 (23.08%) showed slightly hyperintense signal on the same phase T1WI, and 20 (76.92%) showed low or equal signal on the ipsilateral Tl WI. On T2WI, 24 nodules of DN group showed low signal intensity, while 24 of 26 nodules in SHCC group showed heterogeneous isointense signal, slightly high signal intensity or high signal intensity, accounting for 92.31%, and only 2 showed low signal intensity on T2WI. The ratio is 7.69. In Gd-DTPA dynamic enhanced scanning, 15 DN of 14 patients in DN group were found to be of slow ascending and fast descending type, the proportion was 93.33.The irregular reticular fibrous septum was found in 13 DN patients, and the proportion was 86.67%. Only one DN showed pseudocapsular enhancement. In the SHCC group, 24 SHCC of 14 patients were of rapid ascending and fast descending type, the proportion was 92.31, of which 17 cases were capsule enhancement, the proportion was 70.83%. Conclusion High-field MRI can effectively highlight the features of degenerative nodules and early small hepatocellular carcinoma in patients with liver cirrhosis, so as to make diagnosis and see table diagnosis.
