Evolution of the technologist specialist in gastrointestinal radiology.

Over the past few years, a program was initiated at the author's institution to train radiologic technologists to perform the fluoroscopic aspect of gastrointestinal examinations. The program was undertaken in an attempt to improve patient flow through the division, as well as in response to the decreasing number of residents being accepted into the radiology program. The results with respect to diagnostic quality of examination, improved patient flow, and patient and resident acceptance have been satisfactory.

Gastroduodenal response to low-dose glucagon.

A prospective, double-blind clinical study of the double-contrast upper gastrointestinal examination involving 240 patients was performed using glucagon in doses from 0.025 to 0.125 mg, in 0.025 mg increments. Although motility was diminished, neither gastric distension or coating was improved with the use of glucagon. However, duodenal distension and coating were markedly enhanced. The response of the pylorus was individualistic. The pylorus remained patent in most patients, and glucagon would not prevent barium spillage in the duodenum. However, in those patients with a "competent" pylorus, increasing glucagon doses produced a delay in gastric emptying. Several other variables, including weight, age, and gender, were studied and were not believed to be of clinical significance. Spontaneous gastroesophageal reflux was also increased with the use of glucagon. Glucagon mainly enhanced duodenal visualization but had no beneficial effect on the stomach or pylorus. Absolute dose is the most important factor, and all observable changes can be seen once a certain threshold dose (0.05 mg) is reached.
