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.
通过CT和灰阶超声对四个不寻常的盆腔肿块进行研究，展示了这些检查方法在身体该部位的比较价值。在每个病例中，一种或两种技术都对诊断做出了重要贡献。超声检查在区分实性和囊性病变方面略胜一筹，但CT扫描能最清晰地显示该区域的解剖结构，还能提供观察骨骼和软组织细节的方法。
