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.
