摘　　要：目的:探究动态增强磁共振成像(DCE-MRI)、扩散加权成像(DWI)联合成像技术在前列腺脓肿诊断中的应用效果及临床价值。方法:纳入本院2019年1月~2022年12月前列腺脓肿患者(n=40)进行研究,将其作为前列腺脓肿组,同期本院40名健康体检者作为对照组,两组均接受DCE-MRI、DWI成像,对比单一成像与联合成像技术诊断敏感性、特异性与准确性,比较两组ADC值、Ktrans、Kep、Ve参数。结果:DCE-MRI检测前列腺脓肿组阳性32例,DWI检出30例,联合诊断检出38例,联合诊断敏感性、准确性分别为95.0%、97.5%,优于DCE-MRI、DWI单一诊断,差异有统计学意义(P<0.05),不同诊断方式特异性差异比较无统计学意义(P>0.05);前列腺脓肿组ADC值低于对照组,差异有统计学意义(P<0.05),Ktrans、Kep高于对照组,两组Ve比较差异无统计学意义(P>0.05)。结论:DCE-MRI、DWI联合成像技术诊断前列腺脓肿敏感性、准确性高,能够显示脓肿壁及分隔,实现全方面诊断,具有较高临床价值。Objective:To explore the application effect and clinical value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)and diffusion weighted imaging(DWI)in the diagnosis of prostatic abscess.Methods:The patients with prostate abscess(n=40)in our hospital from January 2019 to December 2022 were included in the study,and they were taken as the prostate abscess group.At the same time,40 healthy people in our hospital were taken as the control group.Both groups received DCE-MRI and DWI imaging.The sensitivity,specificity and accuracy of single imaging and combined imaging technology were compared,and the ADC value,Ktrans,Kep and Ve parameters of the two groups were compared.Results:There were 32 positive cases in the group of prostate abscess detected by DCE-MRI,30 cases detected by DWI,and 38 cases detected by combined diagnosis.The sensitivity and accuracy of combined diagnosis were 95.0%and 97.5%,respectively,which were superior to single diagnosis by DCE-MRI and DWI,and the difference was statistically significant(P<0.05).There was no statistically significant difference in the specificity of different diagnostic methods(P>0.05);The ADC value of the prostate abscess group was lower than that of the control group,and the difference was statistically significant(P<0.05).Ktrans and Kep were higher than that of the control group.There was no statistically significant difference in Ve between the two groups(P>0.05).Conclusion:DCE-MRI and DWI combined imaging technology has high sensitivity and accuracy in the diagnosis of prostatic abscess,can display the abscess wall and partition,and realize the diagnosis in all aspects,and has high clinical value.
