title: Quantitation of atherosclerosis in femoral arteriography with ECG gated exposures.
abstract: 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.
