Effect of calibration methods on the accuracy of angiographic measurements during transcatheter procedures in dogs.

Published in: Journal of veterinary internal medicine (2018)

Angiographic image calibration using a ruler placed on the fluoroscopy table underestimates the size of a structure by ∼10% as compared with a marker catheter placed within the esophagus. This effect is greatest when measuring larger structures such as the pulmonary valve annulus and in larger dogs.
