title: Unusual pelvic masses: a comparison of computed tomographic scanning and ultrasonography.
abstract: Four unusual pelvic masses, studied by CT and gray scale ultrasonography, demonstrate the comparative values of these modalities for this area of the body. In each instance a significant contribution to the diagnosis was made by one or both techniques. The ultrasound study provides a somewhat better differentiation of solid from cystic lesions, but the CT scan denotes to best advantage the anatomy of the area, and provides a means of viewing bone as well as soft tissue detail.
