摘要:
目的 探究IVIM相关参数及纹理特征鉴别前列腺癌及前列腺增生的价值。方法 收集2020年11月-2021年8月在安徽医科大学附属省立医院行前列腺MRI检查的43例患者的临床资料，其中前列腺癌患者23例设为前列腺癌组，前列腺增生患者20例设为前列腺增生组。比较两组IVIM相关参数值[水分子扩散系数（D）、伪扩散系数（D*）及灌注分数（f）]，采用ROC曲线分析IVIM相关参数及纹理特征参数对前列腺癌及前列腺增生的鉴别价值。结果 前列腺癌组D及f值小于前列腺增生组，D*值大于前列腺增生组，差异有统计学意义（P＜0.05）；ROC曲线分析显示，D值诊断价值中等（0.7＜AUC＜0.9），f值诊断效能较高（AUC＞0.9），而D*值对前列腺癌及前列腺增生的诊断无意义；一致性、四分位间距、90百分位数、熵、Id对前列腺癌及前列腺增生的诊断价值较高（AUC＞0.9）。结论 IVIM相关参数D、f值及纹理特征参数统一性、四分位间距、90百分位数、熵、Id对前列腺癌及前列腺增生的鉴别有一定价值。
Abstract:
Objective To explore the value of IVIM-related parameters and texture features in the identification of prostate cancer and prostatic hyperplasia.Methods The clinical data of 43 patients with prostate MRI examination in Provincial Hospital Affiliated to Anhui Medical University from November 2020 to August 2021 were collected, including 23 patients with prostate cancer as prostate cancer group and 20 patients with prostatic hyperplasia as prostatic hyperplasia group. The IVIM related parameters [water molecular diffusion coefficient (D), pseudo diffusion coefficient (D*) and perfusion fraction (f)] were compared between the two groups. ROC curve was used to analyze the value of IVIM related parameters and texture parameters in the differential diagnosis of prostate cancer and hyperplasia.Results D and f values of prostate cancer group were lower than those of prostatic hyperplasia group, D* value was higher than that of prostatic hyperplasia group, the difference was statistically significant (P<0.05). ROC curve analysis showed that the diagnostic value of D value was medium (0.7<0.9),>0.9).Conclusion IVIM related parameters D, f value and texture characteristic parameter unity, interquartile spacing, 90th percentile, entropy, and Id are valuable in the identification of prostate cancer and prostatic hyperplasia./html>
