前列腺成像报告和数据系统版本2（PI-RADSv 2）发布了一组最低技术标准（MTS），以提高图像质量并减少多参数前列腺MRI的变异性。PIRADSv 2 MTS对图像质量的影响尚未得到确认。我们的目的是确定是否坚持PI-RADSv 2 MTS提高研究充分性和感知质量。纳入了12个月内（2017年9月至2018年9月）从62家不同机构连续转诊至我中心的62例前列腺MRI检查，包括T2加权（T2 W）和弥散加权成像（DWI）。6名阅片人评估图像是否足以用于PCa检测，并使用1-5分量表进行数字图像质量评级。将PI-RADSv 2 MTS分别合成为T2 W和DWI的7条和10条规则。使用医学数字成像和通信（DICOM）元数据评估图像依从性。基于T2和DWI质量评估的阅片人质量评分（Kendall Rank tau-b）和阅片人充分评分（Wilcoxon关联检验），对调查结果和图像依从性进行统计分析。在62张图像中，52张（83%）T2 W和38张（61%）DWI被大多数阅片者评定为充分。阅片者充分性评分与PI-RADSv 2依从性无显著相关性。PIRADSv 2 MTS依从性与T2 W图像质量之间存在微弱（tau-b = 0.22）但显著（p值= 0.01）的相关性。遵循所有PI-RADSv 2 T2 W规则的研究获得了更高的中位平均质量评分（7/7为3.58，<7/7为3.0，p = 0.012）。PI-RADSv 2 MTS依从性和DWI质量之间无统计学关系。在62个进行前列腺MRI的研究中心中，少数被认为是高质量的，但大多数被认为是足够的。DWI显示样本中充分研究的比率相当低。遵守PI-RADSv 2 MTS并没有增加获得定性充分的T2 W或DWI的可能性。
The Prostate Imaging Reporting and Data System version 2 (PI-RADSv2) published a set of minimum technical standards (MTS) to improve image quality and reduce variability in multiparametric prostate MRI. The effect of PIRADSv2 MTS on image quality has not been validated. We aimed to determine whether adherence to PI-RADSv2 MTS improves study adequacy and perceived quality. Sixty-two prostate MRI examinations including T2 weighted (T2W) and diffusion weighted image (DWI) consecutively referred to our center from 62 different institutions within a 12-month period (September 2017 to September 2018) were included. Six readers assessed images as adequate or inadequate for use in PCa detection and a numerical image quality ranking was given using a 1–5 scale. The PI-RADSv2 MTS were synthesized into sets of seven and 10 rules for T2W and DWI, respectively. Image adherence was assessed using Digital Imaging and Communications in Medicine (DICOM) metadata. Statistical analysis of survey results and image adherence was performed based on reader quality scoring (Kendall Rank tau-b) and reader adequate scoring (Wilcoxon test for association) for T2 and DWI quality assessment. Out of 62 images, 52 (83%) T2W and 38 (61%) DWIs were rated to be adequate by a majority of readers. Reader adequacy scores showed no significant association with adherence to PI-RADSv2. There was a weak (tau-b = 0.22) but significant (p value = 0.01) correlation between adherence to PIRADSv2 MTS and image quality for T2W. Studies following all PI-RADSv2 T2W rules achieved a higher median average quality score (3.58 for 7/7 vs. 3.0 for <7/7, p = 0.012). No statistical relationship with PI-RADSv2 MTS adherence and DWI quality was found. Among 62 sites performing prostate MRI, few were considered of high quality, but the majority were considered adequate. DWI showed considerably lower rates of adequate studies in the sample. Adherence to PI-RADSv2 MTS did not increase the likelihood of having a qualitatively adequate T2W or DWI.
