The Prostate Imaging Quality (PI-QUAL) score is a metric to evaluate the diagnostic quality of multiparametric magnetic resonance imaging (MRI) of the prostate. This study evaluated the impact of a prostate MRI quality training lecture on the participant's ability to assess prostate MRI image quality.
Eighteen in-training-radiologists of varying experience in reviewing diagnostic prostate MRI assessed the image quality of ten examinations. Then, they attended a dedicated lecture on MRI quality assessment using the PI-QUAL score. After the lecture, 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 (ROC) analysis. The reference standard was the PI-QUAL score assessed by a fellowship trained abdominal radiologist with experience in reading prostate MRI.
There was a significant improvement in the average area under the curve (AUC) for assessment of prostate MRI image quality from baseline (0.82; [0.576 - 0.888]) to post teaching (1.0; [0.954-1]), with an improvement of 0.18 (p < 0.03). When ROC curves were computed for different cohorts stratified based on year of training, difference ranged from 0.48 for second year residents to 0.32 for fourth year residents (p < 0.001-0.01). For abdominal imaging fellows, the pre-teaching AUC was 0.9 [0.557-1] and post teaching AUC was 1 [0.957-1], a difference of 0.1 (p = 0.20).
A dedicated lecture on PI-QUAL improved the ability of radiologists-in-training to assess prostate MRI image quality, with variable impact depending on year of training.
前列腺成像质量（PI-QUAL）评分是一种评估前列腺多参数磁共振成像（MRI）诊断质量的指标。本研究评估了前列腺 MRI 质量培训讲座对参与者评估前列腺 MRI 图像质量能力的影响。
18 名不同经验水平的在培放射科医生对 10 项检查的图像质量进行了评估。然后，他们参加了一个专门的讲座，介绍了使用 PI-QUAL 评分评估 MRI 质量的方法。讲座后，同一名参与者使用 PI-QUAL 评分评估了另一组新的 10 个扫描的图像质量。结果采用受试者工作特征（ROC）分析进行评估。参考标准是由一位具有阅读前列腺 MRI 经验的腹部放射学研究员 fellowship培训人员评估的 PI-QUAL 评分。
基线时评估前列腺 MRI 图像质量的平均曲线下面积（AUC）从 0.82（[0.576-0.888]）显著提高到教学后（1.0 [0.954-1]），提高了 0.18（p < 0.03）。当根据培训年限对不同队列的 ROC 曲线进行计算时，差异范围从第二年住院医师的 0.48 到第四年住院医师的 0.32（p < 0.001-0.01）。对于腹部成像研究员，教学前 AUC 为 0.9 [0.557-1]，教学后 AUC 为 1 [0.957-1]，差异为 0.1（p = 0.20）。
专门的 PI-QUAL 讲座提高了放射科住院医师评估前列腺 MRI 图像质量的能力，培训年限的不同对其影响也不同。
