Magnetic resonance imaging (MRI) is essential for assessing shoulder conditions. This study aimed to evaluate current shoulder MRI practices in Jordan, including technical parameter patterns, and determine if they adhere to the American College of Radiology (ACR) guidelines. The retrospective analysis included data from 48 eligible participants from 13 MRI centers in March 2021. Descriptive and correlation data analysis were performed using IBM SPSS statistics version_20 and Excel 2013. Most MRI centers (50%) were private outpatient clinics with closed MRI machines above 1 Tesla. Most participants (62.5%) were male, and shoulder pain (47.9%) was the main clinical indication. Most shoulder orientations (68.7%, 33/48) were right shoulders, and the coronal MRI planes (43%, 121/280) were the most common. The alignment percentage for the axial plane was 100%, but MRI artifacts of the shoulder were present in 8.2% of cases (23/280). Dark fluid T1-W coronal sequence was not conducted in 25% of the cases. The percentage of the field view (FOV) within ACR recommendations was 45% (126/281), and slice thickness parameters were 96% (269/281). The recommended pixel area for all sequences was 47.9% (134/280), encompassing all axial, sagittal oblique, and coronal planes. However, crucial parameters, such as FOV and slice thickness, were inadequate and did not meet the ACR guidelines, resulting in suboptimal image quality of shoulder MRI. To improve MRI image quality, it is recommended that MRI technologists receive ongoing education and training on appropriate MRI image parameters.
磁共振成像（MRI）是评估肩部状况的重要手段。本研究旨在评估约旦目前的肩部 MRI 实践情况，包括技术参数模式，并确定其是否符合美国放射学院（ACR）的指南。这项回顾性分析纳入了 2021 年 3 月来自 13 个 MRI 中心的 48 名符合条件的参与者的数据。采用 IBM SPSS statistics version_20 和 Excel 2013 进行描述性和相关性数据分析。大多数 MRI 中心（50%）为私立门诊，使用 1 特斯拉以上的封闭 MRI 机。大多数参与者（62.5%）为男性，肩部疼痛（47.9%）是主要的临床指征。大多数肩部方位（68.7%，33/48）为右侧，冠状位 MRI 平面（43%，121/280）最常见。轴向平面的对准百分比为 100%，但 8.2%（23/280）的病例存在肩部 MRI 伪影。在 25%的病例中未进行暗液 T1-W 冠状序列。FOV 在 ACR 推荐范围内的比例为 45%（126/281），切片厚度参数为 96%（269/281）。所有序列推荐的像素面积为 47.9%（134/280），包括所有轴向、矢状斜位和冠状位。然而，关键参数，如 FOV 和切片厚度，不足且不符合 ACR 指南，导致肩部 MRI 图像质量不佳。为了提高 MRI 图像质量，建议 MRI 技术员接受有关适当 MRI 图像参数的持续教育和培训。
