Abstract:
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.
