目的:分析前列腺增生及前列腺癌鉴别诊断中采取3.0T动态增强磁共振成像的价值.方法:筛选本院2022年9月~2023年9月就诊的可疑前列腺癌患者,入组对象共110例.全体患者入院后开展常规磁共振平扫、DWI及3.0T动态增强磁共振成像,诊断金标准全部参考穿刺或手术病理结果,分析3.0T动态增强磁共振成像对前列腺增生及前列腺癌的鉴别诊断价值;对比前列腺增生及前列腺癌患者3.0T动态增强磁共振成像参数的差异.结果:病理诊断结果提示,全体110例可疑前列腺癌患者中75例为前列腺癌,35例为前列腺增生;3.0T动态增强磁共振成像分别检出74例、36例.其诊断灵敏度达到97.33%,特异度达到97.14%,准确率达到97.27%,阳性预测值达到98.65%,阴性预测值达到94.44%.对比最大信号强度、最早强化率、速率常数(Kep)、容积运转常数(Ktrans)各项参数,前列腺癌组相较前列腺增生组均显著升高(P<0.05);对比峰值时间、Ve各项参数,前列腺癌组相较前列腺增生组均显著减少(P<0.05).结论:前列腺增生及前列腺癌鉴别诊断中采取3.0T动态增强磁共振成像体现出理想诊断效果,两组间相关影像参数存在明显差异,以此为依据进行疾病诊断保证了较高准确性.
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.
