Method and means for detection of arterial lesions

摘要

The atherosclerotic plaques which form arterial lesions have been found to take up lipoproteins from the blood flowing through the arteries. Accordingly, the early detection of arterial disease is accomplished by preparing an infusate composed of radiolabeled low-density lipoproteins and introducing the infusate into the patient's arterial system. A gamma radiation detector is then used to detect and quantify concentrations of the radiolabeled proteins thereby to indicate the locations and sizes of the lesions.
