Radiology 1995;197(P):303. Further advances to improve specificity by enhancing sensitivity to slow flow and increasing spatial resolution are necessary before routine clinical use of MR pulmonary angiography is justified.

For several years, catheter-based pulmonary angiography was the standard imaging technique for the evaluation of the pulmonary arteries. Current pulmonary CTA techniques involve ever lower doses of contrast medium and radiation along with advanced postprocessing applications to enhance image quality, diagnostic accuracy, and provide added value in patient management. 6.

University of Virginia Health Sciences Center Department of Radiology This tutorial covers the analysis and systematic evaluation of CT Pulmonary Angiography. A pulmonary angiography is typically performed to measure the pressure of the blood vessels carrying blood to your lungs and to evaluate for blockages or … 7 The veins used for catheterization of the pulmonary artery are the femoral, jugular and upper extremity vein. Van Rossum AB, Pattynama PM, Treurniet FE, Schpers R, Kieft GJ. o Fleischner sign refers to local widening of artery by impaction of embolus (due to distension by clot / pulmonary hypertension developing secondary to peripheral embolization) Conclusion: Conventional pulmonary angiography is a minimally invasive procedure performed most frequently by an interventional radiologist or interventional cardiologist. CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries.Its main use is to diagnose pulmonary embolism (PE). Simplified Well’s score for patients with suspected PE. With proper precautions the procedure is acceptably safe even in critically ill patients.

Presence of a thrombus, which appears as a filling defect or as a sudden cutoff of blood flow in a pulmonary arterial branch, establishes the diagnosis of PE.
