Pulmonary angiography

[1] The accuracy of pulmonary angiography may be higher than clinical examination, arterial blood gas results, and ventilation/perfusion scan.

[3] CT pulmonary angiography has nearly entirely replaced conventional pulmonary angiography in common practice as it is less invasive, faster, safer, and provides most of the same diagnostic information with the added benefit of visualizing the lung tissue as well as other structures.

Tip of the catheter is advanced through the inferior vena cava, right atrium, right ventricle, right ventricular outflow tract, pulmonary trunk, and the tip is parked in the left pulmonary artery.

[4] Conventional pulmonary angiography was first performed in 1931 by Portuguese angiography pioneers Lopo de Carvalho, Egas Moniz and colleagues.

[5] Robb and Steinberg described pulmonary angiography by infusion of peripheral radiocontrast.
