摘要

目的前列腺成像质量评分系统第2版（PI-QUAL v2）是一种用于评估前列腺磁共振成像（pMRI）诊断质量的新评分系统。本研究探讨了集中训练模块对MRI技术人员（MRI- tech）和MRI- tech学生评估pMRI图像质量能力的影响。方法采用不同pMRI经验水平的mri专业学生和有经验的mri专业人员共39人参与研究。在专门的pMRI图像质量评估讲座前后，使用PI-QUAL v2评分对20台pMRI图像质量进行评估。在讲座前后计算每位评分者的受试者工作特征（ROC）曲线，按经验分层，并与专门从事pMRI的放射科医生分配的PI-QUAL v2评分进行比较，采用DeLong检验。结果pMRI图像质量评价AUC从干预前（0.31±0.05）到干预后（0.97±0.01）有显著改善，改善幅度为0.66 (p <；0.001)。经验分层的ROC曲线显示，二年级MRI-Tech学生的改善为0.44[0.50±0.07-0.94±0.01](p <；0.001)，三年级的mri学生为0.48[0.46±0.09-0.94±0.01](p <；0.032)和0.60[0.33±0.10-0.93±0.01](p <；0.001)。结论PI-QUAL v2培训模块提高了mri技术学生和委员会认证的mri技术人员评估pMRI图像质量的能力。

Impact on MRI technologist of a PI-QUAL v2 educational program on prostate MRI image quality assessment

Purpose

The Prostate Imaging Quality scoring system version 2 (PI-QUAL v2) is a new scoring system used to assess the diagnostic quality of prostate magnetic resonance imaging (pMRI). This study investigated the impact of a focused training module on the ability of MRI technologists (MRI-Tech) and MRI-Tech students to evaluate pMRI image quality.

Methods

Thirty-nine subjects including MRI-Tech students and experienced MRI-Tech with different levels of experience in pMRI participated in the study. The image quality of twenty pMRIs was evaluated before and after a dedicated lecture on pMRI image quality assessment using PI-QUAL v2 score. Receiver Operating Characteristic (ROC) curves were calculated for each scorer before and after the lecture, stratified by experience, and compared to the PI-QUAL v2 score assigned by a radiologist specialized in pMRI, using DeLong test.

Results

A significant improvement in AUC of pMRI image quality assessment was observed: from the baseline (0.31 ± 0.05) to the post-intervention (0.97 ± 0.01), with an improvement of 0.66 (p < 0.001). The ROC curves stratified by experience, demonstrated an improvement of 0.44 [0.50 ± 0.07–0.94 ± 0.01] for II-year MRI-Tech students (p < 0.001), of 0.48 [0.46 ± 0.09–0.94 ± 0.01] for III-year MRI-Tech students (p < 0.032) and 0.60 [0.33 ± 0.10–0.93 ± 0.01] for board-certified MRI-Techs (p < 0.001).

Conclusions

The PI-QUAL v2 training module improved the ability of both MRI-Tech students and board-certified MRI-Techs to assess the quality of pMRI images.
