前列腺成像质量(PI-QUAL)评分是评价多参数磁共振成像(MRI)对前列腺诊断质量的一项新指标。这项研究评估了一项干预措施，即前列腺MRI质量培训讲座，对参与者应用PI-QUAL的能力的影响。16名参与者(放射科医生、泌尿科医生、物理学家和计算机科学家)在回顾诊断前列腺癌MRI方面有不同的经验，他们都评估了来自不同供应商和机器的10种检查的图像质量。然后，他们参加了一次专门的讲座，随后是一个关于使用PI-QUAL评分进行MRI质量评估的动手研讨会。学员评估的五种扫描在研讨会上使用PI-QUAL分数进行了评估，用于教学目的。课程结束后，同样的参与者应用PI-QUAL评分评估了一组新的10次扫描的图像质量。使用接收器工作特性分析对结果进行评估。参考标准是PI-QUAL的一个开发者评估的PI-QUAL评分。图像质量评价的平均曲线下面积从基线(0.59[95%可信区间：0.5~0.66])到教学后(0.96[0.92~0.98])有显著改善，提高了0.37[0.21~0.41](p<；0.001)。关于PI-QUAL的教学课程(专业讲座+实践工作坊)显著改进了该评分系统在评估前列腺MRI检查质量方面的应用。·在教育干预后，PI-QUAL在评估前列腺MR图像质量方面的应用有了显著改善。·可向参与获取和解释前列腺癌核磁共振的人员提供适当的图像质量培训。·需要进一步调查，以了解对提高高质量诊断性前列腺磁共振检查的获取的影响。网上版载有补充材料，可在10.1007/s00330-022-08947-5查阅。
The Prostate Imaging Quality (PI-QUAL) score is a new metric to evaluate the diagnostic quality of multiparametric magnetic resonance imaging (MRI) of the prostate. This study assesses the impact of an intervention, namely a prostate MRI quality training lecture, on the participant’s ability to apply PI-QUAL. Sixteen participants (radiologists, urologists, physicists, and computer scientists) of varying experience in reviewing diagnostic prostate MRI all assessed the image quality of ten examinations from different vendors and machines. Then, they attended a dedicated lecture followed by a hands-on workshop on MRI quality assessment using the PI-QUAL score. Five scans assessed by the participants were evaluated in the workshop using the PI-QUAL score for teaching purposes. After the course, the same participants evaluated the image quality of a new set of ten scans applying the PI-QUAL score. Results were assessed using receiver operating characteristic analysis. The reference standard was the PI-QUAL score assessed by one of the developers of PI-QUAL. There was a significant improvement in average area under the curve for the evaluation of image quality from baseline (0.59 [95 % confidence intervals: 0.50–0.66]) to post-teaching (0.96 [0.92–0.98]), an improvement of 0.37 [0.21–0.41] (p < 0.001). A teaching course (dedicated lecture + hands-on workshop) on PI-QUAL significantly improved the application of this scoring system to assess the quality of prostate MRI examinations. • A significant improvement in the application of PI-QUAL for the assessment of prostate MR image quality was observed after an educational intervention. • Appropriate training on image quality can be delivered to those involved in the acquisition and interpretation of prostate MRI. • Further investigation will be needed to understand the impact on improving the acquisition of high-quality diagnostic prostate MR examinations.
