摘要目的测试前列腺影像报告数据系统(第2版)(PI-RADS V2)检测标准以及标准调整建议对Gleason评分≥7(GS≥7)的前列腺癌的诊断影响。材料与方法 2名放射科医生分别根据PI-RADS V2对343个前列腺MRI检查出的明显病灶进行评分。GS≥7的肿瘤评价以MRI和超声的联合靶向活检结果作为参考标准。评估PI-RADS V2和一系列推荐的探索性调整对GS≥7的肿瘤检出的影响。结果共有210个良性病灶,43个为GS=6病灶,90个为GS≥7的病灶。GS≥7的病灶在PI-RADS评为1分和2分的病变中占0~
Abstract Objective To test the diagnostic value of the Prostate Imaging Report Data System (Version 2) (PI-RADS V2) and the standard adjustment recommendations for prostate cancer with Gleason score ≥7 (GS ≥7). Materials and Methods Two radiologists scored 343 significant lesions of prostate MRI according to PI-RADS V2. Tumor evaluation of GS ≥ 7 The combined biopsy results of MRI and ultrasound were used as a reference standard. Assess the impact of PI-RADS V2 and a series of recommended exploratory adjustments on the detection of tumors with GS ≥ 7. Results There were 210 benign lesions, 43 lesions were GS = 6 and 90 lesions were GS≥7. Lesions with GS ≥ 7 accounted for 0% in lesions rated 1 and 2 PI-RADS
