摘　　要：目的分析MRI在前列腺移行区良恶性病变中的诊断价值及误诊原因。方法选取147例前列腺移行区病变患者,分析MRI在前列腺移行区良恶性病变中的诊断价值和误诊原因。结果MRI诊断的准确率为78.23%,误诊率为21.77%;与病理诊断结果的一致性较高(Kappa=0.816,P<0.001)。MRI对前列腺移行区良恶性病变诊断价值较高,曲线下面积(AUC)为0.767。病变形态、信号均匀度、边界情况、包膜情况、扩散加权成像(DWI)信号强度、表观扩散系数(ADC)值和时间-信号强度曲线类型均为影响MRI在前列腺移行区良恶性病变诊断中误诊的独立危险因素(P<0.05)。结论MRI在前列腺移行区良恶性病变中的诊断价值较高。病变形态、信号均匀度、边界情况、包膜情况、DWI信号强度、ADC值和时间-信号强度曲线类型是诊断中误诊原因。Objective To analyze the diagnostic value and misdiagnosis reasons of MRI in benign and malignant prostatic transitional zone lesions.Methods A total of 147 patients with prostatic transitional zone lesions were selected.The diagnostic value and misdiagnosis reasons of MRI in benign and malignant prostatic transitional zone lesions were analyzed.Results The accuracy rate of MRI diagnosis was 78.23%,and the misdiagnosis rate was 21.77%.MRI had high consistency with the pathological diagnosis results(Kappa=0.816,P<0.001).MRI had high diagnostic value in benign and malignant prostatic transitional zone lesions,and the area under the curve(AUC)was 0.767.The shape,signal uniformity,boundary condition,capsule condition,diffusion weighted imaging(DWI)signal intensity,apparent diffusion coefficient(ADC)value,and time-signal intensity curve type of the lesion were all independent risk factors for misdiagnosis of benign and malignant prostatic transitional zone lesions using MRI(P<0.05).Conclusion MRI has high diagnostic value in benign and malignant prostatic transitional zone lesions.The causes of misdiagnosis are lesion shape,signal uniformity,boundary condition,capsule condition,DWI signal intensity,ADC value,and time-signal intensity curve type.
