4. CT pulmonary angiography is now the first-line imaging technique to evaluate pulmonary arterial diseases, including acute pulmonary embolism (PE). Objective: To determine the overall sensitivity and specificity for CT pulmonary angiography (CTPA) in the diagnosis of pulmonary emboli (PE) using a meta-analysis of the published literature. The rapid progress in cross-sectional imaging techniques offers a great help in the development of a reliable, accurate, and readily available technique for diagnosing pulmonary embolism , . 2nd Ed. [Medline]. [Medline]. Historically, catheter-directed pulmonary angiography has been used most commonly for the diagnosis of suspected pulmonary embolism (PE). For patients with renal failure or other contraindications to iodinated contrast material, CO2 may safely be used as a contrast agent; (B) On late arterial phase imaging, there is early opacification of an inferior right pulmonary vein (arrow heads) draining the AVM. 2011 Apr. pulmonary angiography Pulmonary arteriography Imaging A technique in which radiocontrast is injected into the pulmonary arteries and its branches by percutaneous catheter placed in the internal jugular or the common femoral veins Indications Identification of PTE aneurysms, AV malformations, pulmonary … Screen COPD Patients With Worsening Lung Function for Pulmonary Embolism?

Moos JM, Ham SW, Han SM, Lew WK, Hua HT, Hood DB. CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. 7 The veins used for catheterization of the pulmonary artery are the femoral, jugular and upper extremity vein. Hence, the aim of our study was a balanced comparison between V/Q lung scintigraphy and CT angiography using advanced imaging techniques for both modalities.

Zuckerman DA, Sterling KM, Oser RF. 1981 Mar. 2014 Apr. AJR Am J Roentgenol. Arch Surg. Pulmonary angiography is considered the gold standard for the diagnosis of PE, although recent evidence does not necessarily always support that. Use a catheter that has side-holes, such as a pigtail, to decrease the risk of damaging the vasculature, Have some means of creating a 90° or near 90° angle within several centimeters of the distal portion of the catheter to improve maneuverability through the right heart. CTPA was introduced in the 1990s as an alternative to ventilation/perfusion scanning, which relies on radionuclide imaging of the blood vessels of the lung. 2007 Jul. Tip of catheter in the main pulmonary artery. To minimize the risk of adverse reactions, low osmolar nonionic contrast should be used. 136(3):624-6. This technique is able to create pictures of the blood vessels in the chest and upper abdomen.
