Eighty-one pediatric patients with a variety of spinal disorders, including suspected dysrhaphism, scoliosis, neoplasia, and neurofibromatosis, underwent magnetic resonance (MR) imaging. The results were retrospectively compared with those of myelography followed by computed tomography (CT) and surgery. In patients with dysrhaphism, most abnormalities, including hydromyelia, inclusion tumors, and sites of cord tether, were demonstrated with MR imaging. Diastematomyelia and small hydromyelic cavities were indistinguishable on routine coronal and sagittal T1-weighted images; axial images with T2 weighting were optimal for this differentiation. MR imaging did not enable direct visualization of a thickened filum or evaluation of tethering with a thin, dorsally positioned neural placode. Congenital or severe scoliosis required lengthy studies with multiple planes of imaging or myelography and CT. Milder curvatures were readily evaluated with MR imaging, and neoplastic lesions, with the exception of intrathecal tumor seeding, were adequately defined.
81例患有各种脊柱疾病的儿科患者接受了磁共振（MR）成像检查，这些疾病包括疑似脊柱裂、脊柱侧凸、肿瘤和神经纤维瘤病。将结果与脊髓造影后计算机断层扫描（CT）及手术结果进行回顾性比较。在脊柱裂患者中，大多数异常情况，包括脊髓空洞症、包涵体肿瘤和脊髓栓系部位，均可通过MR成像显示。在常规冠状面和矢状面T1加权图像上，脊髓纵裂和小的脊髓空洞难以区分；T2加权的轴位图像最适合进行这种区分。MR成像无法直接显示增厚的终丝，也无法评估与薄的、位于背侧的神经板的栓系情况。先天性或严重脊柱侧凸需要进行多平面成像或脊髓造影及CT的长时间检查。较轻的脊柱侧弯通过MR成像很容易评估，除鞘内肿瘤播散外，肿瘤性病变也能得到充分界定。
