Abstract
PURPOSE: To study the appearance and distribution of vertebral compression fractures on magnetic resonance (MR) images in patients with multiple myeloma. MATERIALS AND METHODS: Two hundred twenty-four vertebral compression fractures were studied on 216 sagittal T1-weighted spin-echo and T2*-weighted gradient-echo MR images of the thoracolumbar spine obtained before and during treatment in 37 patients with multiple myeloma. Vertebral compression fractures observed at diagnosis and during follow-up were determined as being benign- or malignant-appearing at MR imaging according to literature criteria, and their distribution along the spine was recorded. RESULTS: One hundred forty-nine (67%) of the 224 vertebral compression fractures appeared benign; 75 (33%) appeared malignant. Of the 37 patients, 14 (38%) had only benign-appearing vertebral compression fractures at diagnosis. One hundred five fractures (87%) were observed between T-6 and L-4, and 112 (50%) occurred between T-11 and L-3. Eight (4%) vertebral...Keywords
