title: 105 mm photofluorography: an adjunct to the study of coronary arterial and vascular disease.
abstract: Obtaining high resolution static films through an image intensifier has been made possible by recent developments in radiographic equipment. Serial photofluorography 105 mm spot filming has been used successfully to complement cine coronary arteriography in approximately 700 patients. Many patients with coronary heart disease have diffuse peripheral atheromatous changes which are also suitable to study by serial 105 mm photofluorography. Aortic arch, abdominal aortography, and peripheral studies are easily and quickly performed in conjunction with coronary arteriography. Satisfactory results still depend upon skillful application by the angiographer of this imaging mode and proper processing of the film. Advantages of photofluorographic filming over conventional large film techniques include lower radiation exposure, reduction of costs, and easier film handling and storage. Most important is the facilitation of the performance of angiographic studies since constant television monitoring of the catheter and the contrast injections is possible. Disadvantages include restricted area of coverage and slight decrease in resolution. Our experience indicates that photofluorography may be relied upon in the study of vascular disease eliminating the need for large film changers in a laboratory used primarily for cardiac diagnosis.
