1 MR images and plain radiograph of an 82-year-old woman who had compression fractures and osteonecrosis at the L3 vertebral body. MR images and plain radiograph of an 82-year-old woman who had compression fractures and osteonecrosis at the L3 vertebral body. There is only intravertebral fluid in the mildly collapsed vertebral body. A, Sagittal T1-weighted turbo spin-echo image (600/12, 4-mm section thickness) shows complete bone marrow replacement by low signal intensity (arrow). B, Sagittal T2-weighted turbo spin-echo image (4000/128) shows homogeneous hyperintensity at the anterior superior portion of the vertebral body (arrow). The margin of the hyperintense area is well demarcated. C, Sagittal contrast-enhanced T1-weighted fat-suppressed turbo spin-echo image (700/12, 4-mm section thickness) shows nonenhancement of the anterior and superior portions of the vertebral body (arrow). The nonenhancing area corresponds to the hyperintense area of the T2WI in panel B. The remaining portion of this vertebral body had faint enhancement. D, Lateral view of plain radiograph shows faint radiolucent area at anterior superior portion of the vertebral body (arrow). The radiolucent area corresponds to the T2 hyperintnese area in the panel B. C.-W. Yu et al. AJNR Am J Neuroradiol 2007;28:42-47 ©2007 by American Society of Neuroradiology
