摘　　要：目的研究磁共振成像(magnetic resonance imaging,MRI)平扫、弥散加权成像(diffusion weighted imaging,DWI)及动态增强扫描对前列腺良恶性病变的鉴别诊断价值。方法选择2019年2月—2023年12月东莞市樟木头医院收治的80例疑似恶性前列腺病变患者为研究对象,以手术诊断或穿刺病理结果作为金标准,对所有患者均实施MRI平扫、DWI及动态增强扫描,比较不同检查方式的诊断结果与诊断效能。结果手术诊断或穿刺病理结果显示,阴性67例,阳性13例;联合扫描阴性69例,阳性11例;动态对比增强磁共振成像(dynamic contrast enhancement magnetic resonance imaging,DCE-MRI)扫描阴性62例,阳性18例;MRI平扫阴性50例,阳性30例。联合扫描的灵敏度为97.01%(65/67)、特异度为69.23%(9/13),准确度为92.50%(74/80),均高于MRI平扫的67.16%(45/67)、61.54%(8/13)、66.25%(53/80)与DCE-MRI的82.09%(55/67)、46.15%(6/13)、76.25%(61/80),差异有统计学意义(P均<0.05)。结论前列腺良恶性病变鉴别诊断中运用MRI平扫、DWI及动态增强扫描诊断方式,可提升鉴别诊断效能。Objective To study the value of magnetic resonance imaging(MRI)plain scan,diffusion weighted imaging(DWI)and dynamic enhanced scan in the differential diagnosis of benign and malignant prostate lesions.Methods A total of 80 patients with suspected malignant prostate lesions admitted to Dongguan Zhangmutou Hospital from February 2019 to December 2023 were selected.The results of surgical diagnosis or puncture pathology were used as the gold standard.All patients underwent routine MRI plain scan,DWI and dynamic enhanced scan.The diagnostic results and diagnostic efficacy of different examination methods were compared.Results The results of surgical diagnosis or puncture pathology showed negative in 67 cases and positive in 13 cases.There were 69 positive cases and 11 negative cases on combined scan,62 negative cases and 18 positive cases on DCE-MRI,and 50 negative cases on plain MRI.There were 30 positive cases.The sensitivity of the combined scan was 97.01%(65/67),the specificity was 69.23%(9/13),and the accuracy was 92.50%(74/80).The results were higher than those of MRI plain scan 67.16%(45/67),61.54%(8/13),66.25%(53/80)and DCE-MRI82.09%(55/67),46.15%(6/13),76.25%(61/80),and the differences were statistically significant(all P<0.05).Conclusion The use of MRI plain scan,DWI and dynamic enhanced scan in the differential diagnosis of benign and malignant prostate lesions can improve the differential diagnosis efficiency.
