pulmonary angiography

Etymology: L, pulmoneus, lungs; Gk, angeion, vessel, graphein, to record
the radiographic examination of the blood vessels of the lungs after the injection of radiopaque contrast medium into the pulmonary circulation. It is used to detect pulmonary emboli.

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 artery stenosis

Pulmonary angiography

An x-ray study of the lungs, performed by insertion of a catheter into a vein, through the heart, and into the pulmonary artery. Pulmonary angiography is performed to evaluate blood circulation to the lungs. It is also considered the most accurate diagnostic test for detecting a pulmonary embolism.

angiography

radiological demonstration of certain areas of the vascular system by the injection of a radiopaque solution (arteriography, lymphangiography or phlebography).

brain angiography
radiography of the cranium after the intravenous injection of a radiopaque substance. An area of poor vascularity indicates the presence of a space-occupying lesion in the brain.
fluorescein angiography
intravenous fluorescein can be visualized in retinal and iris vasculature with the use of blue filters and direct or indirect ophthalmoscopy or photography. See also vitreous fluorophotometry.
nonselective angiography
injection of contrast material into a regional vessel or the general circulation.
orbital angiography
contrast study of the arteries of the orbit, particularly the malar, infraorbital, maxillary and dorsal orbital, using the infraorbital artery for injection of a suitable medium.
pulmonary angiography
demonstration of pulmonary veins and arteries by introduction of contrast material into the jugular or cephalic vein or via a catheter positioned in the pulmonary artery.
renal angiography
outlines renal blood flow, usually via a catheter introduced into the femoral artery and passed retrograde into the aorta to the vicinity of the renal arteries.
selective angiography
placement of the catheter in the vessel or heart chamber being studied in order to provide the best possible contrast study of the suspected lesion.

In patients with a contraindication to iodinated contrast who can receive gadolinium, combined MR pulmonary angiography and MR venography can be performed.
However, reducing the need for pulmonary angiography, which is an invasive, expensive method associated with morbidity and mortality, and not available in all centers, may be possible with the identification of patients with high, medium, and low levels of clinical probabilities, and with the use of other non-invasive diagnostic methods, such as V/Q scintigraphy together with CTPA.
Is it enough to compare d-dimer concentrations only to pulmonary angiography in patients with suspected pulmonary embolism?
Gadolinium-enhanced magnetic resonance pulmonary angiography (MRPA) can also be used to diagnose PE, and has the advantage of being radiation free.
After obtaining Royal Perth Hospital Ethics Committee approval (075/2012), clinical, laboratory and radiology data of consecutive patients who had symptoms suggestive of acute PE requiring computed tomography pulmonary angiography (CTPA) to exclude acute PE over a four-month period (January to April 2012) in five metropolitan hospitals (Royal Perth Hospital, Sir Charles Gairdner Hospital, Fremantle Hospital, Swan District Hospital and Rockingham Hospital) in Western Australia were obtained.
When conventional or CT pulmonary angiography cannot be performed, magnetic resonance angiography (MRA) becomes a valuable option.
Although 5% to 10% of the studies are nondiagnostic, the same problem exists with standard pulmonary angiography.
Her previous pregnancy had been complicated by extensive bibasal pulmonary emboli, confirmed by computed tomography pulmonary angiography (CTPA) four weeks after delivery.
However, pulmonary angiography is necessary before embolotherapy or other intervention is undertaken.
17, 2010 /PRNewswire/ -- MEDRAD will offer RSNA* attendees hands-on demonstrations of personalized-protocol software that individualizes CT Pulmonary Angiography (CTPA) contrast dosing, and has proven to increase the percentage of diagnostic-quality studies to rule out Pulmonary Embolism (PE) when compared to the institution's standard protocol(1)** -- potentially obviating the need to rescan the patient.
