Four patients with proved osteopetrosis (three with the infantile malignant form and one with the benign form) were examined with magnetic resonance imaging at 1.5 T. All patients were studied in the coronal and sagittal planes using both short and long repetition time/echo time sequences. The infantile malignant form was characterized by a complete lack of signal from the marrow alternating with a signal intensity equivalent to that of the intervertebral disks, resulting in a "stepladder" appearance. In the benign form or after successful marrow transplantation in the infantile malignant form, intermediate or high signal intensity in the vertebrae was noted, suggesting the presence of some marrow elements.
对4例经证实的骨硬化症患者（3例为婴儿恶性型，1例为良性型）进行了1.5T磁共振成像检查。所有患者均采用短和长重复时间/回波时间序列在冠状面和矢状面进行研究。婴儿恶性型的特征是骨髓完全无信号，与椎间盘信号强度相当的信号交替出现，形成“阶梯状”外观。在良性型或婴儿恶性型成功进行骨髓移植后，椎体内可见中等或高信号强度，提示存在一些骨髓成分。
