摘　　要：目的:观察磁共振成像(MRI)动态增强扫描联合弥散加权成像(DWI)检查在原发性肝癌诊断中的效能。方法:回顾性分析2022年1月至2023年1月于该院就诊的143例疑似原发性肝癌患者的临床资料,均进行MRI动态增强扫描、DWI和病理检查,以病理检查结果为金标准,统计MRI动态增强扫描、DWI单项及联合检查诊断原发性肝癌的结果,并分析其与病理检查结果的一致性,比较MRI动态增强扫描、DWI单项及联合检查在原发性肝癌诊断中的效能。结果:病理检查结果显示,143例疑似原发性肝癌患者中,阳性96例,阴性47例;MRI动态增强扫描检查检出阳性83例,阴性60例,与病理检查诊断原发性肝癌的一致性一般(Kappa=0.689);DWI检查检出阳性86例,阴性57例,与病理检查诊断原发性肝癌的一致性一般(Kappa=0.669);联合检查检出阳性99例,阴性44例,与病理检查诊断原发性肝癌的一致性较高(Kappa=0.855);MRI动态增强扫描联合DWI检查诊断原发性肝癌的灵敏度、准确度、阴性预测值均高于二者单项检查,差异有统计学意义(P<0.05);MRI动态增强扫描、DWI单项及联合检查诊断原发性肝癌的特异度、阳性预测值比较,差异均无统计学意义(P>0.05)。结论:MRI动态增强扫描联合DWI检查在原发性肝癌诊断中的效能高于二者单项检查。Objective:To observe efficiency of magnetic resonance imaging(MRI)dynamic enhanced scan combined with diffusion weighted imaging(DWI)in diagnosis of primary liver cancer.Methods:The clinical data of 143 patients with suspected primary liver cancer who were treated in this hospital from January 2022 to January 2023 were retrospectively analyzed.All patients underwent MRI dynamic enhanced scan,DWI and pathological examination.Using the pathological examination results as the gold standard,the results of single and combined examination of MRI dynamic enhanced scan and DWI in the diagnosis of primary liver cancer were statistically analyzed,and their consistencies with pathological examination results were analyzed.The efficiencies of single and combined examination of MRI dynamic enhanced scan and DWI in the diagnosis of primary liver cancer were compared.Results:The pathological examination showed that among the 143 patients with suspected primary liver cancer,96 cases were positive and 47 cases were negative.MRI dynamic enhanced scan detected 83 positive cases and 60 negative cases,and the consistency with pathological examination in the diagnosis of primary liver cancer was general(Kappa=0.689).DWI examination detected 86 positive cases and 57 negative cases,and the consistency with pathological examination in the diagnosis of primary liver cancer was general(Kappa=0.669).MRI dynamic enhanced scan combined with DWI detected 99 positive cases and 44 negative cases,and the consistency with pathological examination in the diagnosis of primary liver cancer was high(Kappa=0.855).The sensitivity,accuracy and negative predictive value of MRI dynamic enhanced scan combined with DWI in the diagnosis of primary liver cancer were higher than those of the two single examinations,and the differences were statistically significant(P<0.05).However,there were no significant differences in the specificity and the positive predictive value of single and combined examination MRI dynamic enhanced scan and DWI in the diagnosis of pri
