摘　　要：目的分析多层螺旋CT(MSCT)与磁共振功能成像(MRI)对前列腺癌患者的诊断价值。方法对我院2018年10月~2023年7月收治的前列腺癌患者80例临床资料进行分析研究。同时纳入我院同期前列腺良性病变患者作为参照组。患者均进行MSCT检查与MRI检查。分析两种检测方式对前列腺癌的诊断价值。结果与良性病变者比较,前列腺癌患者MSCT参数指标血容量(RBV)、相对血流量(RBF)、表面通透性(PS)更高(P<0.05)。与良性病变组比较,前列腺癌患者MRI检测各参数指标中峰值时间、强化幅度更低,峰值与强化率更高(P<0.05)。ROC分析显示:MSCT的预测AUC为0.892,MRI的AUC为0.886,敏感度、特异度分别为98.8%、63.7%;90.0%、72.5%;两者联合AUC达0.948,敏感度、特异度为98.8%、88.7%。结论MSCT与MRI对前列腺癌的诊断均具有一定价值,单位避免单一检测的造成的局限性,建议临床中结合多累检测进行两个诊断。Objective To analyze the diagnostic value of multi-slice spiral CT(MSCT)and magnetic resonance functional imaging(MRI)in patients with prostate cancer.Methods The clinical data of 80 patients with prostate cancer admitted to our hospital from October 2018 to July 2023 were analyzed and studied.Meanwhile,patients with benign prostatic lesions in our hospital were included as the reference group.All patients underwent MSCT examination and MRI examination.To analyze the diagnostic value of two detection methods in prostate cancer.Results Compared with benign lesions,MSCT parameters of blood volume(RBV),relative blood flow(RBF)and surface permeability(PS)in prostate cancer patients were higher(P<0.05).Compared with the benign lesion group,the peak time and enhancement amplitude of MRI in prostate cancer patients were lower,and the peak and enhancement rate were higher(P<0.05).ROC analysis showed that the predicted AUC of MSCT was 0.892 and that of MRI was 0.886,and the sensitivity and specificity were 98.8%and 63.7%,respectively.90.0%,72.5%;The combined AUC was 0.948,and the sensitivity and specificity were 98.8%and 88.7%.Conclusion Both MSCT and MRI have a certain value in the diagnosis of prostate cancer.The unit avoids the limitations caused by single detection,and it is recommended to combine the two diagnostic tests in clinical practice.
