Abstract

Purpose: To establish a standardized method of reformatting axial images for computed tomography (CT) brain examinations.

Methods: An anatomic line between the superior orbital rim and the base of the occipital bone (SOR-BS line) was chosen as the standardized reference line. In June 2022, CT technologists at a tertiary care center received an educational presentation and a 1-page reference handout on making standardized CT reformats. This was the quality-of-care intervention. Subsequently, 100 CT brain examinations performed on July 1 to 10, 2020 (preintervention) were analyzed and compared with 100 CT brain examinations performed on July 1 to 10, 2022 (postintervention).

Results: There were no significant differences in the mean angle differences measured between the preintervention (6.2 ± 5.8°) and the postintervention (5.8 ± 4.7°) groups (P = .67). However, the number of CT brain studies with an angle difference of more than 20° decreased from 4 studies to 1 study. In addition, the number of CT brain studies without reformatted images decreased from 5 to 2 studies.

Discussion: The cause for the less-than-optimal adoption of the expected change in CT workflow might be complex and multifactorial. However, the institution in this study is a busy tertiary care center with a chronic shortage of CT technologists. The busy workflow might have contributed to lack of significance for the parameters assessed.

Conclusion: There was a slight but not significant improvement between preintervention and postintervention data.

建立创建角度校正、重新格式化脑 CT 图像的标准。

目的：建立计算机断层扫描（CT）脑部检查轴向图像重新格式化的标准化方法：方法：选择眶上缘与枕骨基底之间的解剖线（SOR-BS 线）作为标准化参考线。2022 年 6 月，一家三级医疗中心的 CT 技术人员收到了关于制作标准化 CT 重整图的教育讲座和 1 页参考手册。这就是护理质量干预。随后，对2020年7月1日至10日（干预前）进行的100例脑部CT检查与2022年7月1日至10日（干预后）进行了分析和比较：干预前（6.2 ± 5.8°）和干预后（5.8 ± 4.7°）两组测量的平均角度差异无明显差异（P = .67）。然而，角度差超过 20° 的脑部 CT 研究从 4 项减少到 1 项。此外，未重新格式化图像的脑部 CT 研究从 5 项减少到 2 项：讨论：CT 工作流程中的预期变化未得到最佳采用的原因可能是复杂的、多因素的。然而，本研究中的医疗机构是一家繁忙的三级医疗中心，长期缺乏 CT 技术人员。繁忙的工作流程可能是导致评估参数缺乏显著性的原因之一：干预前和干预后的数据有轻微改善，但不明显。
