Imaging techniques to assess the pelvis in young females

This article is designed to help the nonradiologist to form a logical imaging plan when presented with a diagnostic dilemma involving the pelvis of a young female. Common presenting problems are grouped under the categories of fetus, neonate and infant, child, and adolescent. Ultrasound is frequently the initial, and sometimes the only, examination indicated. The appropriateness of other modalities, such as plain radiography, genitography, computed tomography, and magnetic resonance imaging, is described. Details of examination performance and interpretation are beyond the scope of this discussion, but can be gleaned from the references cited.
