Magnetic resonance imaging (MRI) is the most appropriate imaging method to investigate low back pain. As low back pain is very common, a large number of MRI scans are performed.
To evaluate the extraspinal findings and clinical effect of the T1-weighted spin echo (T1W SE) coronal sequence added to the lumbar MRI protocol for low back pain.
In 2015, we added a T1-weighted (T1W) coronal sequence to our routine lumbar MRI protocol. We retrospectively evaluated 969 lumbar MRI images for low back pain performed with this protocol. The extraspinal MRI findings obtained from them were then grouped as associated with low back pain (Category 1) and not associated with low back pain (Category 2). We also evaluated whether the recorded incidental extraspinal findings could be detected on conventional sagittal and axial images.
Ninety-six (63%) of the extraspinal findings were associated with low back pain (Category 1) and 56 (37%), Category 2. Seventy-eight percent of the extraspinal findings were detected only on coronal-T1W images and not on conventional images.
Adding coronal-T1W sequence to the routine protocol of lumbar MRI can help to identify extraspinal findings and guide clinical treatment.
磁共振成像（MRI）是研究下腰痛最适宜的影像学方法。由于下腰痛非常常见，因此进行了大量的 MRI 扫描。
评估 T1 加权自旋回波（T1W SE）冠状序列添加到腰椎 MRI 方案中对下腰痛的脊柱外发现和临床效果。
2015 年，我们在常规腰椎 MRI 方案中添加了 T1 加权（T1W）冠状序列。我们回顾性评估了 969 例接受该方案检查的下腰痛腰椎 MRI 图像。然后将这些图像中的脊柱外 MRI 发现分为与下腰痛相关（第 1 类）和与下腰痛不相关（第 2 类）。我们还评估了记录的偶然脊柱外发现是否可以在常规矢状位和轴位图像上检测到。
96 个（63%）脊柱外发现与下腰痛相关（第 1 类），56 个（37%）为第 2 类。78%的脊柱外发现仅在冠状-T1W 图像上发现，而在常规图像上未发现。
在常规腰椎 MRI 方案中添加冠状-T1W 序列可以帮助识别脊柱外发现并指导临床治疗。
