| scintigraphic angiography | The measurement of visualization by radiation of any organ after a radionuclide has been injected into its blood supply. It is used to diagnose heart, liver, lung, and other diseases and to measure the function of those organs, except renography, for which radioisotope renography is available. (12 Dec 1998) |
|---|---|
| selective angiography | <procedure, radiology> Angiography in which visualization is improved by concentrating the contrast medium in the region to be studied by injection through a catheter positioned in a regional artery. (05 Mar 2000) |
| digital subtraction angiography | Computer-assisted roentgenographic angiography permitting visualization of vascular structures without superimposed bone and soft tissue density; images made before and after contrast injection allow subtraction (separation and removal) of opacities not enhanced by the contrast medium. Other image-processing can be performed. Contrast material may be injected intravenously or in lower-than-usual amount intra-arterially. (05 Mar 2000) |
| therapeutic angiography | Use of angiographic catheters that have been modified to reduce or increase regional blood flow, or to deliver medicinal agents; interventional therapeutic angiography. See: angioplasty, balloon catheter, interventional angiography. (05 Mar 2000) |
| fluorescein angiography | <procedure> The process of taking X-rays of blood vessels that have been injected with a special dye. The dye allows to person viewing the X-ray to see the blood vessels. (13 Nov 1997) |
