Advances in radiologic reporting with Computerized Language Information Processing (CLIP).

Computerized Language Information Processing (CLIP) is a system of radiologic reporting in which the user interacts with a computer keyboard and cathode-ray tube terminal to generate coded reports. The hierarchical medical classification on which the code is based permits rapid on-line compilation of reports of any degree of complexity. The system provides organized sets of pre-assembled statements that are rapidly accessed and modified for each examination. Although the reports are printed in English, they are held in the computer as a succinct code that is eminently suited for permanent storage and rapid retrieval.

Renal failure following major angiography.

Acute renal failure following angiography with contrast agents is known to occur, but the circumstances and frequency of its occurrence are not well described. A retrospective review of consecutive angiographic procedures performed over a six month interval revealed a 12 per cent incidence of renal failure following angiography. The degree of failure was severe in approximately 30 per cent of these cases and was associated with a significant mortality even though renal function usually recovered. The occurrence of renal failure was associated with the presence of renal insufficiency, impaired liver function, diabetes mellitus, hypoalbuminemia and proteinuria at the time of angiography to a statistically significant level. Furthermore, combinations of these factors, particularly preexisting combined renal insufficiency and impaired liver function, were associated with an increased incidence of acute renal failure. It is concluded that angiography poses a significant hazard to patients with underlying medical problems, particularly those involving the excretory routes of the contrast agent.

A comparison of fluoroscopically controlled patient positioning and conventional positioning, including comparative dosimetry.

The size of the area of exposure on the skin during excretory urography was determined by either technician-controlled fluoroscopy or conventional assessment in 2 comparable groups of patients. The mean skin exposure to radiation per patient was the same in each group. The time required for a urogram was 10% less when fluoroscopy was employed. Since accurate, tightly shuttered exposure areas improve radiographic quality, fluoroscopically controlled determination of patient positioning is justified.
