pulmonary angiography (redirected from Pulmonary arteriography)

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.

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.

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.
