FIG 1. Involvement of a single vertebra.
A, Midsagittal T1-weighted image in a patient 6 months after spine radiation for breast metastases who presented with new pain and a positive radionuclide bone scan. This image shows hypointensity and partial wedge deformity of T7 (arrow). Note that vertebrae above and below the lesion are hyperintense as a result of prior radiation therapy.
B, Corresponding T2-weighted image shows lesion (arrow) to be minimally hypointense with respect to presumed normal bone marrow above and below.
C, Corresponding diffusion-weighted image shows that T7 (arrow) is hypointense relative to other vertebrae. Although the abnormality is perhaps seen better on diffusion-weighted image than on the T2-weighted image, the diffusion-weighted image is not superior to the T1-weighted image.
