Computed tomography of the abdomen.

In a few short years, computed tomography has become an important diagnostic procedure in the examination of the abdomen and pelvis. Its forte lies in its ability to provide cross-sectional views of excellent anatomical detail. Imaging of deep-seated structures such as the pancreas, adrenal glands, and enlarged retroperitoneal lymph nodes is now possible. The ability to distinguish small variations in tissue density enables the radiologist to evaluate the texture of solid structures, and to differentiate them from cysts or abscesses. The addition of contrast enhancement makes it possible to determine the vascularity of a lesson. The major limitation of CT is poorer delineation of structures in thin patients, and in patients in whom voluntary and involuntary motion cannot be interrupted. Computed tomography is compared with other complementary imaging procedures to include sonography, radionuclide imaging, and conventional radiograph procedures. It has replaced invasive diagnostic procedures in many instances. In a given situation, one or more imaging modalities may be appropriate.

Efficacy of computed tomography of the abdomen--early results.

Our experience with 153 CT scans of the abdomen and pelvis over the first eight months of availability at our institution has been analyzed. The efficacy in terms of contribution to the diagnosis in each patient was assessed and accuracy determined. CT was found to have made a significant contribution to the diagnosis in patients with diseases of the pancreas, aorta, retroperitoneal structures, and in cases of abdominal and pelvic masses and abcesses. It has been somewhat less helpful in evaluation of liver and renal diseases. Overall, CT scanning appears to be a significant new diagnostic modality in the evaluation of patients with abdominal and pelvic diseases.

Experience with 111-In-chloride scanning in patients with focal defects on 99-mTc-sulfur colloid liver scans.

Thirty-nine patients with focal defects on the technetium liver scan were rescanned using 111-In chloride. Of 20 patients with hepatic malignancy, 11 had positive indium scans. None of the 19 with focal cirrhotic fibrosis had a positive indium scan although 5 of these had primary tumor. Thus, a positive indium scan suggests that the defect is malignant. A negative indium scan is less helpful, failling to distinguish between neoplasm and focal cirrhosis. Positive uptake in an extrahepatic primary neoplasm and negative uptake in the liver suggest that the hepatic lesion is not neoplastic.

Postmortem radiology of head neck injuries in fatal traffic accidents.

A series of 146 victims of fatal traffic accidents were subjected to postmortem radiographic examination prior to medicolegal autopsy. A total of 42% were found to have radiographically demonstrable head injuries ranging from relatively simple linear skull fractures to massive skull damage. Free intracranial or intravascular air was demonstrated in more than 60%. A total of 21% had demonstrable neck injuries, most of which were localized to a single level at the craniocervical junction or the upper two cervical vertebrae. Flexion and extension studies of this area are of major importance in demonstrating the injury and locating potentially occult lesions for the forensic pathologist.
