磁共振弥散加权成像(DWI)作为分子水平上观察组织结构的无创性检查新技术,已逐步应用于肌肉骨骼系统[1-6],近年来主要应用于椎体良恶性压缩骨折的鉴别诊断[2,7-8]及椎体转移瘤的诊断[9-10]。笔者对20例正常人及37例(61处)腰椎椎体骨髓病变行MRI DWI检查,观察病变的信号强度并
Magnetic resonance diffusion-weighted imaging (DWI) has been gradually applied to the musculoskeletal system as a new noninvasive technique to observe the tissue structure at molecular level [1-6] and has been mainly used in the differential diagnosis of benign and malignant vertebral compression fractures in recent years [ 2,7-8] and the diagnosis of vertebral metastases [9-10]. The author of 20 cases of normal subjects and 37 cases (61) of the lumbar vertebral bone marrow lesions MRI DWI check the signal intensity of lesions and
