骨骼系统放射学基础（7）——正常颈椎和脊髓的MRI表现

Figure 7 Normal appearance of the cervical spine and spinal cord on magnetic resonance imaging. A sagittal (lateral) view with a T1-weighted sequence (A) shows that the subcutaneous fat and marrow within the vertebral bodies have a high signal and appear white. The cerebrospinal fluid (CSF) appears almost black, and the cerebellum, pons, and spinal cord appear gray. On the T2-weighted sequence (B), the contrast is somewhat reversed, with fluid or CSF appearing white, and the fat becoming dark. The spinal cord remains gray.
