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
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/mm2 in malignant patients were lower than those in benign patients,and the MR units of 600,900,1200,1500,1800,and 2100s/mm2 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.
