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 drive-by renal angiography, the test is being done because it is easy and considered to be risk free, not because the physician believes that the patient's renal arteries need examining.
40) The patients were subjected to renal angiography, and the clinical characteristics of the population were analyzed to determine a clinical predictive score for the probability of renovascular disease.
