Fig 1. A, A 64-year-old man with multiple myeloma. Sagittal T2-weighted MR image demonstrates several mild lumbar compression fractures with a normal appearance of L2 (arrow).
B, A follow-up sagittal MR image obtained 4 weeks later demonstrates a new compression fracture of L2 (arrow) without any associated edema.

Fig 2. A, A 47-year-old man with multiple myeloma. Sagittal T2-weighted MR image demonstrates a compression fracture of T7 (arrow) without any significant edema.
B, A sagittal T1-weighted MR image reveals no edema in the superior endplate.

Fig 3. A, A sagittal fat-saturated T2-weighted image demonstrates increased signal intensity (arrow) in the superior endplate from an acute compression fracture in a different patient.
B, A sagittal spin-echo T1-weighted image in this patient nicely demonstrates the decreased signal intensity in the same superior endplate (arrow).
C, An image from a whole-body bone scintigraphy study demonstrates the classic horizontal radiotracer uptake (arrows) in acute vertebral body compression fractures.
