Clinical Analysis of 3.0T Dynamic Enhanced Magnetic Resonance Imaging in Differential Diagnosis of Prostate Hyperplasia and Prostate Cancer
Objective:To evaluate the value of 3.0T dynamic enhanced magnetic resonance imaging in differential diagnosis of prostate hyperplasia and prostate cancer. Methods:A total of 110 patients with suspected prostate cancer who visited our hospital from September 2022 to September 2023 were selected. All patients underwent routine magnetic resonance plain scan,DWI and 3.0T dynamic enhanced magnetic resonance imaging after admission. Meanwhile,the diagnostic gold standard was all based on puncture or surgical pathological results. The value of 3.0T dynamic enhanced magnetic resonance imaging in the differential diagnosis of prostate hyperplasia and prostate cancer was analyzed. The parameters of 3.0T dynamic enhanced magnetic resonance imaging were compared between patients with prostate hyperplasia and prostate cancer. Results:Pathological diagnosis indicated that 75 of the 110 suspected cases of prostate cancer were prostate cancer and 35 were prostate hyperplasia.3.0T dynamic enhanced magnetic resonance imaging detected 74 and 36 cases respectively. The diagnostic sensitivity,specificity,accuracy,positive predictive value and negative predictive value reached 97.33%,97.14%,97.27%,98.65%,94.44%. The parameters of maximum signal intensity,earliest strengthening rate,rate constant (Kep) and volume running constant (Ktrans) were significantly higher in prostate cancer group than in prostate hyperplasia group (P<0.05). The peak time and Ve parameters in prostate cancer group were significantly reduced compared with those in prostate hyperplasia group (P<0.05). Conclusion:In the differential diagnosis of prostate hyperplasia and prostate cancer,3.0T dynamic enhanced magnetic resonance imaging showed an ideal diagnostic effect,and there were significant differences in related image parameters between the two groups,which ensured high accuracy of disease diagnosis.
