A special 8-channel detector arrangement was used to determine atraumatically the mean blood flow velocities in the aorta and the large arteries of the lower extremities in man. Following intravenous injection of 99mTc-pertechnetate time-activity curves were recorded over defined measuring points over the arteries, from these the appearance times of the tracer determined, and the mean blood flow velocities calculated from the differences between appearance times (the minimal transit times) and the distances between measuring points. The simultaneous determination of the minimal transit times between the vena cava inferior and the root of the aorta, which correspond closely to the total cardiac transit times, permits recognition of cases in whom blood flow velocity is reduced as a result of cardiac disease.
采用一种特殊的8通道探测器装置，以无创方式测定人体主动脉和下肢大动脉的平均血流速度。静脉注射高锝[99mTc]酸盐后，记录动脉上特定测量点的时间-活性曲线，由此确定示踪剂的出现时间，并根据出现时间（最短通过时间）与测量点之间距离的差值计算平均血流速度。同时测定下腔静脉与主动脉根部之间的最短通过时间，该时间与心脏总通过时间密切对应，有助于识别因心脏病导致血流速度降低的病例。
