Ultrasonography and computed tomography in the diagnosis of homogeneous masses
Abstract:
Ultrasonography can demonstrate the homogeneity, while CT can demonstrate the density of a mass lesion. If a mass appears echo-free at ultrasonography, but is denser than water at CT, a solid tumor with grossly uniform cellular structure (usually a lymphoma or sarcoma), or a hematoma or hemorrhagic cyst is likely. However, if the mass has water density at CT, a cystic lesion is confirmed. One case for each category is presented.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
