FIG 3. Patient with diffuse involvement from an unknown primary tumor, with hyperintensity on diffusion-weighted images.
A, Sagittal T1-weighted image shows diffuse hypointense metastatic involvement. There are compression fractures involving T12, T9, L5, and L3.
B, Corresponding T2-weighted image shows diffuse hyperintensity without focal lesions throughout all vertebrae visualized.
C, Corresponding diffusion-weighted image shows that the diffuse lesions are mostly hyperintense with minimal patchy appearance. The lesions are better seen on the T1-weighted image than on the T2- and diffusion-weighted sequences.
