Pulmonary Angiography Kyung Cho Nils Kucher Although right heart catheterization was first described in 1929,1 angiographic visualization of the pulmonary arteries was not performed until 1938.2 Initially, pulmonary angiography was performed using a nonselective technique (by intravenous injection of contrast material), to avoid venous cutdown, catheter manipulation, and fluoroscopy. CT angiography gains acceptance in diagnosis of pulmonary emboli. The CT pulmonary angiogram (CTPA) can suggest the presence of PH by morphological changes such as right heart enlargement, increased pulmonary artery (PA) diameter – relative to the aorta – the presence of significant tricuspid regurgitation and a pericardial effusion. Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used to visualize arterial and venous vessels throughout the body. Magnetic Resonance Pulmonary Angiography (MRPA) Magnetic resonance pulmonary angiography (MRPA), although still considered a second-line imagine technique behind CTPA, has been gaining acceptance in the evaluation of VTE.
