Fig 1. Sagittal T1 MR imaging demonstrating fracture types. Stars indicate treated fractures. A, Type 1 fracture, considered probably osteoporotic in nature. Areas of preserved, high T1 signal intensity within the fractured vertebral body, without focal intravertebral lesion and no evidence for pedicle involvement or epidural or paraspinal disease (not shown). B, Type 2 fracture, indeterminate for underlying lesions. Diffusely low signal intensity marrow throughout the spine. No focal lesion or epidural or paraspinal lesion within the treated vertebral body. C, Type 3 fracture, with clear evidence for myelomatous lesion within the treated vertebral body.
