Normal acetabular anatomy for acetabular fracture assessment: CT and plain film correlation.

The computed tomographic (CT) and conventional radiographic appearances of the acetabulum are correlated for assessment of acetabular fractures according to the Judet and Letournel classification system, a system widely used by orthopedic surgeons performing fracture reduction and external fixation of the acetabulum. A desiccated pelvis was marked along the acetabular borders with lead solder, and anteroposterior (AP) and oblique radiographs were obtained. The solder was then replaced by barium-impregnated string, and the acetabulum was scanned by CT. Radiographic-CT correlations of acetabular landmarks should aid the orthopedist by providing a useful interpretation of acetabular fractures according to the Judet and Letournel system.

Artifacts seen during CT pelvimetry: implications for digital systems with scanning beams.

During computed tomography (CT) pelvimetry of two pregnant women, bony abnormalities of the fetuses were noted on the scout images that were not confirmed at delivery. To explore the cause of these artifacts, specimen long bones were manipulated in various ways during CT scout imaging. Artifacts like those seen during in vivo imaging were found to be caused by motion of the object. The CT scout view is an example of an image produced by a digital system that uses a scanning beam. This type of digital system is being used for several types of body imaging including screening for scoliosis and chest radiography. Attention to motion artifacts should decrease diagnostic errors and aid further development of these systems.

Pleural and mediastinal changes following endoscopic injection sclerotherapy of esophageal varices.

Postero-anterior and lateral chest radiographs of patients undergoing endoscopic injection sclerotherapy of esophageal varices were reviewed. Radiographs were obtained prior to and within 48 hours of treatment. Following sclerotherapy, pleural effusions and densities were commonly seen at the azygoesophageal reflection and the posterior wall of the bronchus intermedius; however, on follow-up they had resolved. Most patients were asymptomatic, and morbidity was low. These findings suggest that inflammation developing after endoscopic injection sclerotherapy extends beyond the esophageal wall into the mediastinum and pleural space.
