Conference paper


Volume blood flow is measurable from digital data acquired during angiography and can be plotted as it changes throughout a cardiac cycle. The method has now been introduced on a trial basis during some carotid and vertebral studies at the National Hospital, Queen Square. The results, which fall numerically within the range predicted by 133Xe cerebral blood flow methods, reveal patterns consistent with pathological conditions. It is suggested that the method could provide a Standard to assist and calibrate ultrasonic flow measurement and magnetic resonance quantitative angiography.
