[ECG-triggered DSA of the aortic arch and the supra-aortal vessels of the neck].
220 examinations were conducted in 55 patients (40 men and 15 women) to explore the question whether there are any changes in the area of the aortic arch and the supra-aortal vessels. The examinations were conducted intraindividually according to ECG-triggered and non-ECG-triggered DSA technique. The technical conditions with regard to x-ray film, volume of contrast media, and patient positions, were the same for the purpose of comparing the results with regard to the number of x-ray films, image quality, incidence of artifacts and changes in exposure to irradiation. It was found that ECG-triggered DSA yielded a greater number of diagnostically useful and qualitatively superior images with reduced irradiation exposure in a shorter time than non-ECG-triggered DSA.
