Abstract
The authors used a spin-tagging method of magnetic resonance perfusion imag ing to measure pulmonary perfusion in eight healthy volunteers with use of a respiratory-triggered three-dimensional pulse sequence. The average signa l intensity (SI) decrease upon arterial labeling was 24%. The perfusion SI increased by 21% after exercise (P = .02). Focal blood flow abnormalities w ere observed in a patient with chronic obstructive pulmonary disease.
