ABSTRACT
Use of therapeutic arterial embolization (TAE) in the traumatized patient can achieve rapid control of hemorrhage and obviate the need for immediate surgery on poor-risk patients or in high-risk areas of the body. The techniques of embolization, its risks, and complications are discussed in light of the authors' experience, and a review of recent literature is presented.

A prototype computed radiography (CR) system was evaluated for its efficacy as an independent diagnostic modality. Preliminary measurements of high contrast resolution, low contrast perceptibility, and dose were obtained. Clinical examinations including skull, abdomen, liver, gallbladder, biliary system, spine, and extremities were performed as an adjunct to either computed tomography or CR. The data suggest that CR can be an effective diagnostic imaging modality by itself. Advantages over conventional radiography include high scatter rejection, low patient dose, wide dynamic range, and good low contrast sensitivity for large objects; disadvantages, its long exposure time and relatively poor high contrast spatial resolution.

Ultrasonography was performed in the prone and supine positions in six patients with neoplasms in the tail of the pancreas. The masses were either not apparent (three cases) or less well visualized on the supine scans. The value and indications of the prone position in the ultrasonic evaluation of masses in this portion of the pancreas are documented. Prone scanning is particularly useful when malignant ascites interferes with pancreatic visualization in the supine position.

Three cases of calcified liver metastases demonstrating acoustical shadowing on gray scale ultrasonography are reported. Ultrasonography may show calcified liver masses that are not readily apparent on plain film radiographs. The discovery of calcified liver metastases by ultrasound can suggest a primary site of malignancy.
