Using a densitometric method introduced in 1977 by Crawford et coll. the volumes of segments of the femoral artery were calculated from two angiographic series in each of 13 patients. ECG gated exposures were used to minimise the error of the method. The reproducibility of the method was found to be better than in a previous study in which ECG gating was not used. The method may therefore be of use in long term angiographic follow-up studies of atherosclerotic lesions, although the impact of different investigation parameters on methodologic precision is still not fully known.
采用克劳福德等人于1977年引入的密度测定法，从13例患者每人的两个血管造影系列中计算股动脉各节段的体积。采用心电图门控曝光以尽量减少该方法的误差。结果发现该方法的可重复性优于先前一项未使用心电图门控的研究。因此，该方法可能用于动脉粥样硬化病变的长期血管造影随访研究，尽管不同研究参数对方法学精度的影响仍不完全清楚。
