Abstract
The sacrum is a large bone composed of five fused vertebrae, which contributes stability and strength to the pelvis, transmitting the weight of the body to the pelvic girdle. It is located at the crossroads of the pelvis and lower extremities, and the anatomy and pathology of the sacrum is of interest to neuroradiologists as well as to body imagers. Plain films are often non-diagnostic for this region, due to the relatively complex anatomy of the sacrum and the adjacent pelvic bones and due to overlying bowel. Therefore, depending on the specific clinical situations, a variety of cross-sectional imaging techniques are of value for sacral imaging, including CT, MRI, and nuclear medicine studies, and in some of these situations these techniques are complementary to each other. Cross-sectional imaging is also valuable for guiding interventional procedures on the sacrum.
