目的 分析PI-RADS version 2 在区域医疗中心应用的可行性。方法 收 集自2016年2月至今在我院行PI-RADS V2 前列腺检查的患者资料50例，对扫描序 列所需时间进行记录，对图像质量进行 综合评价。结果 50例患者应用PI-RADS 技术参数的总体扫描时间与常规强化检 查时间相似。前列腺高分辨T2WI及动态 增强序列的图像优良率为100%，中等B值 DWI的图像优良率达96%，高B值DWI的图 像优良率为78%。结论 应用PI-RADS v2的 技术参数扫描前列腺可以在区域医疗中 心中推广。

Objective Analyze the feasibility of applying PI-RADS version 2 in the regional medical center. Methods A total of 50 cases of patients with PI-RADS V2 prostate examination in our hospital from February 2016 to now are collected, and the time required for the scanning sequence is recorded and the quality of the image is evaluated synthetically. Results The overall scanning time of the patients with the PIRADS technical parameters was similar to that of the regular enhancement scanning time. The excellent rate of high resolution T2WI and dynamic enhancement sequence of prostate was 100%. Medium B value DWI image excellent rate was 96%, high B value DWI image excellent rate was 78%. Conclusion The technique parameters for applying PI-RADS v2 can be applied to the regional medical center.
