Box 30001, 9700 RB Groningen, The Netherlands, Department of Vascular Medicine, Academic Medical Centre, Amsterdam, The Netherlands. Historically, catheter-directed pulmonary angiography has been used most commonly for the diagnosis of suspected pulmonary embolism (PE). Abstract. Computed tomography pulmonary angiography (CTPA) is currently the preferred thoracic imaging test for patients suspected of having pulmonary embolism (PE) [ 1 ]. Pulmonary embolism: comparison of cut-film and digital pulmonary angiography. However, its "invasive" nature is a limitation and its place in the diagnostic strategy of venous thromboembolic disease is the object of on-going specific clinical trials. Pulmonary angiography remains the only investigation which, in all cases, allows confirmation or exclusion of the diagnosis of pulmonary embolism, providing that the technical quality is satisfactory. Although conventional CT with contrast Pulmonary angiography is performed to evaluate blood circulation to the lungs. All procedures have some risks. Complications and validity of pulmonary angiography in acute pulmonary embolism.

Pulmonary angiography can be used in a diagnostic dilemma, although … cerebral angiography – to check the blood vessels in and around the brain ; pulmonary angiography – to check the blood vessels supplying the lungs ; renal angiography – to check the blood vessels supplying the kidneys ; Occasionally, angiography may be done using scans instead of X-rays. Indications of DSA and conventional pulmonary angiography are principally identical. In 367 consecutive studies our incidence of complications has been 4 per cent, and there has been only one death.

Pulmonary angiography is used to investigate pulmonary circulation when other, less invasive, methods have failed to provide the requisite information. These are called CT angiography or MRI angiography. Use the link below to share a full-text version of this article with your friends and colleagues. Dalen JE, Brooks HL, Johnson LW, et al. Radiology 1996; 201:29-36. Indirect CTV images do not look like CTA images, but they are almost always diagnostic (jus… The most frequent indication is for suspected PE, usually following a nondiagnostic ventilation-perfusion scan (V/Q). Indirect CTV Often combined with CT pulmonary angiography (CTPA) in the acute setting, indirect CTV is performed as a standard, nonoral, post–intravenous contrast-enhanced CT at approximately 120 to 150 seconds after injection of contrast, which is considerably later than portal venous phase. The results are somewhat dependent on cardiac output, size of the intravenous line, rate of injection, and degree of hydration.
