Angiographic techniques combined with simultaneous pressure measurements provide a valid method for calculating the radius-pressure relationship in large human blood vessels.

Angiographic radius-pressure assessment may be valid in large human vessels; leaves open prospective outcome validation before routine use.
The radius of the pulmonary arteries and of the descending thoracic aorta in man was measured by angiographic techniques. Simultaneously with angiocardiography, pressure measurements were carried out, permitting calculation of radius-pressure (ΔR/ΔP) relationships. The results obtained by this method are similar to those obtained by other methods in which the vessel radius was measured more directly.
