混合型肝癌的CT及MRI影像学表现分析

目的研究混合型肝癌(c HCC-CC)的CT及MRI影像资料,分析两种影像检查手段在cHCC-CC临床诊断中的价值。方法对我院2016.05-2018.05期间超声检查高度怀疑为cHCC-CC的90例患者行CT及MRI影像检查(平扫+增强),并最终行手术病理检查。以病理结果为标准,比较两种影像检查方法对cHCC-CC疾病的诊断价值,并总结分析cHCC-CC的CT及MRI影像图像特点。结果 90例cHCC-CC疑似患者病理结果为cHCC-CC者82例,其他8例;CT诊断结果为cHCC-CC者67例,其他23例,灵敏度、特异度、准确度分别为78.05%(64/82)、62.50%(5/8)、76.67%(69/90);MRI诊断结果为cHCC-CC者77例,其他13例,灵敏度、特异度、准确度分别为92.68%(76/82)、75.00%(6/8)、91.11%(82/90);MRI对cHCC-CC诊断正确率高于CT(P<0.05);cHCC-CC的CT及MRI图像具有一定的特征性。结论 cHCC-CC的CT及MRI影像表现具有一定特征性,尤其是增强扫描有利于疾病的诊断及鉴别,且MRI具有更高的诊断价值。

CT and MRI Imaging Findings of Mixed Hepatocellular Carcinoma

Objective To study the CT and MRI imaging data of mixed hepatocellular carcinoma(cHCC-CC) and analyze the value of two imaging methods in the clinical diagnosis of cHCC-CC. Methods 90 cases of patients with high-suspicious cHCCCC during period from May 2017 to May 2018 were given CT and MRI scans(plain scan + enhanced scan), and then were given surgical pathological examination. Based on pathological results, the diagnostic value of two imaging methods for cHCC-CC disease was compared, and the features of CT and MRI images of cHCC-CC were summarized and analyzed. Results Among 90 cases of suspected cHCC-CC patients, 82 cases were cHCC-CC and 8 cases were other diseases by pathological results. 67 cases were cHCCCC and 23 cases were others by CT findings, and the sensitivity, specificity and accuracy were 78.05%(64/82), 62.50%(5/8) and 76.67%(69/90). of 77 cases were cHCC-CC and 13 cases were others by MRI diagnosis, and the sensitivity, specificity and accuracy were 92.68%(76/82), 75.00%(6/8) and 91.11%(82/90). The diagnostic accuracy of MRI for cHCC-CC was higher than that of CT(P<0.05). The CT and MRI images of cHCC-CC had certain characteristics. Conclusion The CT and MRI images of cHCCCC have certain characteristics, especially the enhanced scan is helpful to the diagnosis and identification of disease, and MRI has a high diagnostic value.
