Computed tomography of the osseous pelvis.

Computed tomography (CT) was used for study of the osseous pelvis in 43 patients with definitive pathological or clinical follow-up. CT accurately characterized and determined extent of bone and soft-tissue involvement; neoplasms and other disease processes, such as sacroiliac joint disease, were well localized. In cases of trauma, CT was able to identify, localize, and characterize fracture fragments and bone or joint displacement. CT was judged "useful" or "definitive" in 80% of all lesions and 96% of neoplasms studied.
