MRI多b值扩散加权成像联合多期增强扫描在良恶性前列腺结节鉴别诊断中的价值

The Value of MRI Multi b-Value Diffusion Weighted Imaging Combined with Multi Phase Enhanced Scanning in the Differential Diagnosis of Benign and Malignant Prostate Nodules

目的:探讨良恶性前列腺结节鉴别诊断中MRI多b值扩散加权成像联合多期增强扫描的价值。方法:回顾性选取2020年2月~2022年2月本院前列腺结节患者100例作为病例组、健康体检人员100例作为健康组。结果:多b值DWI联合多期增强扫描的灵敏性、准确性、阴性预测值均高于单独检查。恶性患者的0、300s/mm^(2) MR unit均低于良性患者,600、900、1200、1500、1800、2100s/mm^(2) MR unit均高于良性患者。恶性患者的Sde、Slope b-signal、ADC standard均低于良性患者。病例组中恶性和良性患者的R、SImax%均高于健康组,Tmax均低于健康组,恶性患者的R高于良性患者,Tmax低于良性患者(P<0.05)。结论:良恶性前列腺结节鉴别诊断中MRI多b值扩散加权成像联合多期增强扫描的价值较单独检查高。

Objective:To explore the value of MRI multi b-value diffusion weighted imaging combined with multi phase enhanced scanning in the differential diagnosis of benign and malignant prostate nodules.Methods:From February 2020 to February 2022,100 patients with prostate nodules in our hospital were selected as the case group,and 100 health examination personnel were selected as the health group.Results:The sensitivity,accuracy,and negative predictive value of multi b-value DWI combined with multi phase enhanced scanning were higher than those of single examination.The MR units of 0,300s/mm^(2) in malignant patients were lower than those in benign patients,and the MR units of 600,900,1200,1500,1800,and 2100s/mm^(2) in benign patients were higher than those in benign patients.The Sde,Slope b-signal,and ADC standard of malignant patients were lower than those of benign patients.In the case group,the R and SImax%of malignant and benign patients were higher than those in the healthy group,and the Tmax was lower than those in the healthy group.The R of malignant patients was higher than that of benign patients,and the Tmax was lower than that of benign patients(P<0.05).Conclusion:In the differential diagnosis of benign and malignant prostate nodules,the value of MRI multi b-value diffusion weighted imaging combined with multi phase enhanced scanning is higher than that of single examination.
