[Isotope-angiographic measurement of aortic flow velocity for differential diagnosis of aortic sclerosis].
The speed of flow between aortic arch and abdominal aorta was determined from the corresponding minimal transit time (MTT) measured with 113m-In-DTPA and the Fucks-Knipping gamma camera. A total of 144 individuals was examined: 62 normal persons, 34 patients with cardiac insufficiency; 31 patients with hyperkinetic syndrome (effort syndrome and hyperthyroidism) and 17 patients with isolated aortic sclerosis without impairment of cardiac function. In all individual groups there was a highly significant correlation between speed of flow and heart rate. For a given heart rate speed of flow was diminished in cases of cardiac insufficiency and aortic sclerosis; it was accelerated in patients with hyperkinetic syndrome. By plotting the speed of flow through the aorta, normalized to an arbitary heart rate, against the corresponding MTT, also normalized to the same heart rate, the presence of aortic sclerosis could be differentially recognized in 14 of the 17 patients with this disease.
