Spiculation of antral margin in erosive gastritis.

Because of the low yield, conventional barium studies had been considered an unreliable methods of detecting erosions of the stomach. With the advent of the double contrast examination, the literature is now replete with examples of erosive demonstrated by this technique. As in endoscopy, the erosions are visualized "en face" only. No case, however, has been recorded in which the diagnosis was made on a profile view of the erosions. We present such a case of erosive gastritis with two unusual features in which 1) the diagnosis was made on a conventional single contrast study and 2) the lesions were identified in profile.

Acute renal failure, contrast media, and computer tomography.

Acute renal failure (ARF) is recognized as a potential hazard of intravenous administration of radiologic contrast media (RCM). We present a case of contrast-induced ARF which was first detected on an unenhanced computed tomographic examination of the abdomen. A number of postulated mechanisms in the pathogenesis of ARF are discussed. Multiple factors are associated with an increased probability of ARF when contrast material is given intravenously. The significance of advanced age as a risk factor is discussed. Certain predisposing circumstances are amenable to correction by the radiologist, thereby diminishing the chance of causing contrast-induced ARF.

The wandering broncholith.

In a patient with "stone asthma" the obstructing broncholith moved from one lung to the other and was later spontaneously expectorated.

MR imaging with gadolinium-DTPA in the differentiation of tumor, syrinx, and cyst of the spinal cord.

Intravenous Gd-diethylenetriamine pentaacetic acid was used in 16 patients to differentiate between syringomyelia, syringomyelia in association with tumor, and cystic tumor in the spinal cord. Contrast enhancement occurred in all 12 histologically proven cases of tumor and enabled clear demarcation of neoplastic tissue from syrinx or cyst. Eleven of the twelve tumors seen in association with spinal cord cavitation were malignant; all tumors apart from one (a schwannoma) were intramedullary in location. Enhanced scans were more helpful than unenhanced scans in diagnosing and defining the extent of tumors associated with a syrinx or cyst.

Lingual mandibular bony defects: CT in the buccolingual plane.

OBJECTIVE: Our goal was to record the appearance of lingular mandibular bony defects (LMBD) on CT imaging of the mandible in the buccolingual plane. MATERIALS AND METHODS: During the CT evaluation of patients planning to undergo dental implant surgery, five cases of LMBD were found. Axial 1.2 x 1.00 mm overlapping CT sections of the mandible and the maxilla were obtained. Then with use of specific software (DentaCT; Elscint), panoramic and cross-sectional (buccolingual) images of the mandible and maxilla were reformatted. RESULTS: Five cases of posterior LMBD were identified; one patient had both a posterior as well as the much rarer anterior LMBD. All cases were incidental findings and all were asymptomatic. CT features of LMBD were displayed in axial, panoramic, and buccolingual planes. The characteristic opening of the bony defect in the lingual aspect of the mandible was clearly displayed on the axial as well as the buccolingual images; however, this key feature was not manifest on the panoramic images of the mandible. CONCLUSION: CT features of LMBD in the buccolingual plane are added to the known radiologic description of this entity.

Digital radiography of the chest by self-scanning linear diode arrays.

Diode array digital radiography DADR is a method of radiographic imaging that combines the advantages of computer technology with self-scanning linear diode arrays. These digital images are superior to those obtained by film in recording and displaying information in the lightest and the darkest areas of the film, resulting in a balanced image of the entire thorax without compromising detail, and at reduced radiation dose. This is a direct result of the wide dynamic range, high contrast sensitivity, fiber optic coupling, small diode size, short exposure time, and rejection of scattered x-rays of the system coupled with digital post-processing enhancement of the image displayed at 1024 X 1024 pixels.
