摘要
目的探讨肝细胞癌的影像学特征磁共振成像(magnetic resonance imaging,MRI)、CT的诊断价值。方法选取永州市第三人民医院2022年1月—2023年12月收治的90例肝脏疾病患者,经病理检查确诊肝细胞癌47例(52.22%),良性病变43例(47.78%)。所有患者均进行MRI、CT检查,并对其诊断效能进行比较。结果以病理检查为“金标准”,CT应用于肝细胞癌检查中诊断敏感度最高为76.60%,其次为准确率71.11%、阳性预测值70.59%、特异度为65.12%;MRI应用于肝细胞癌检查中诊断敏感度最高为93.62%,其次为准确率90.00%、阳性预测值88.00%、特异度为86.05%,MRI检查各诊断指标较CT检查更高(P<0.05)。CT、MRI图像均可见动脉期强化特征,且门静脉期可观察到强化减弱,以低密度改变为主要特征,其特点呈现为快进快出。结论MRI诊断肝细胞癌的效能优于CT,能够更好地指导临床诊断该疾病。
Objective To explore the imaging features of hepatocellular carcinoma and the diagnostic value of magnetic resonance imaging(magnetic resonance imaging,MRI)and CT.Methods A total of 90 liver disease patients admitted to the Third People′s Hospital of Yongzhou from January 2022 to December 2023 were collected,47 cases(52.22%)of hepatocellular carcinoma and 43 cases(47.78%)of benign lesions were confirmed by pathological examination.All patients were examined by MRI and CT,and their diagnostic efficacy was compared and analyzed.Results Taking pathological examination as"the gold standard",the diagnostic sensitivity of CT in hepatocellular carcinoma was 76.60%,followed by accuracy 71.11%,positive predictive value 70.59%and specificity 65.12%.The diagnostic sensitivity of MRI for hepatocellular carcinoma was the highest(93.62%),followed by the accuracy of 90.00%,the positive predictive value of 88.00%and the specificity of 86.05%.The diagnostic indexes of MRI were higher than those of CT(P<0.05).CT and MRI images showed enhanced features in arterial phase,and weakened enhancement was observed in portal vein phase,with low density change as the main feature,which was characterized by fast in and fast out.Conclusion MRI is better than CT in the diagnosis of hepatocellular carcinoma,and can guide the clinical diagnosis of this disease better.
