Assessment of the 3-Dimensional shape of bone lesions alone, frequently provides useful diagnostic information. Our data strongly supports the conclusion that a bone lesion that has a highly elliptical shape is very unlikely to represent a metastasis, if centrally located or otherwise unimpeded in its growth directions. This limited study showed a highly significant difference (p<0.01) in bone metastasis shape depending on the degree of contact with the cortical barrier of vertebral bodies.
