摘　　要：目的探讨分别采用弥散加权成像(diffusion weighted imaging,DWI)以及磁共振成像(magnetic resonance imaging,MRI)技术对肝脏良恶性肿瘤患者的诊断效果。方法选取2020年3月—2022年6月枣庄市立医院收治的70例肝脏肿瘤患者作为研究对象,以病理诊断结果为金标准,分别采用DWI技术以及常规MRI技术完成肿瘤良恶性的鉴别诊断,比较不同检查方法的诊断效能,并且对比良恶性肿瘤各性质状态下的弥散系数(apparent diffusion coefficient,ADC)。结果DWI技术诊断的特异度为95.00%,敏感度为96.67%,准确度为95.71%,均优于常规MRI技术诊断的50.00%、66.67%、57.14%,差异有统计学意义(χ^(2)=16.055、7.111、25.037,P<0.05)。恶性肿瘤患者各性质状态下的ADC值均低于良性肿瘤,差异有统计学意义(P<0.05)。结论同常规MRI技术比较,合理选择DWI技术对肝脏肿瘤患者实施良恶性鉴别诊断,可显著提高诊断敏感度、特异度以及准确度,临床鉴别诊断价值显著。Objective To explore the diagnostic effects of diffusion weighted imaging(DWI)and magnetic resonance imaging(MRI)in patients with benign and malignant liver tumors.Methods Seventy patients with liver tumors admitted to Zaozhuang Municipal Hospital from March 2020 to June 2022 were selected as the study objects.Taking pathological diagnosis results as the gold standard,DWI technology and routine MRI technology were used to complete the differential diagnosis of benign and malignant tumors.The diagnostic efficacy of different methods was compared,and the apparent diffusion coefficient(ADC)of benign and malignant tumors was compared.Results The specificity,sensitivity and accuracy of DWI diagnosis were 95.00%,96.67%and 95.71%,which were better than those of conventional MRI diagnosis(50.00%,66.67%and 57.14%),the difference was statistically significant(χ^(2)=16.055,7.111,25.037,P<0.05).The ADC values of malignant tumors were lower than those of benign tumors in all nature states,and the difference was statistically significant(P<0.05).Conclusion Compared with conventional MRI technology,the rational selection of DWI technology for the differential diagnosis of benign and malignant patients with liver tumors can significantly improve the diagnostic sensitivity,specificity and accuracy,and the clinical differential diagnosis value is significant.
