To evaluate the MR appearance of the discovertebral junction (DVJ) of the spine, we examined 161 DVJs in 27 cadaveric spines using superconductive MR imaging. T1-, proton density-, and T2-weighted spin-echo imaging were used. With a small surface coil, higher resolution and more sharply defined contours of the DVJ were obtained than when using a head coil. Cortical bone had very low signal intensity in all sequences. Cartilaginous end-plate (CP) was of low to intermediate signal intensity on T1-weighted images, and of low signal intensity on proton density- and T2-weighted images. MR images were able to reveal the gross CP appearances, Schmorl's nodules, and adjacent bone marrow pathology. We conclude that MR imaging is valuable for assessing abnormalities of the DVJ.
为评估脊柱椎间盘-椎体连接部（DVJ）的磁共振（MR）表现，我们使用超导MR成像对27具尸体脊柱中的161个DVJ进行了检查。采用了T1加权、质子密度加权和T2加权自旋回波成像。使用小表面线圈时，与使用头部线圈相比，可获得更高分辨率且DVJ轮廓更清晰的图像。皮质骨在所有序列中信号强度都非常低。软骨终板（CP）在T1加权图像上呈低至中等信号强度，在质子密度加权和T2加权图像上呈低信号强度。MR图像能够显示CP的大体表现、施莫尔氏结节以及相邻骨髓的病变情况。我们得出结论，MR成像对于评估DVJ的异常情况很有价值。
