How is an angiogram performed?

Dye injection: A tube is placed into a blood vessel and dye is injected. An xray is then done to show the dye flowing through the vessel. If there is a blockage, the vessel becomes narrower or disappears completely.

Invasive exam: A needle is used to blood vessel in the groin or arm. This is used as access site to other blood vessels with a catheter.

Angiogram Answer: A radio opaque dye is injected in your artery near the anatomy to be studied then an Xray is taken to show the vascularity of that area.

Diagnosis: An angiogram is an invasive diagnostic test, perfomed in a catheterization laboratory using fluoroscopy (the x-ray) and an injected contrast dye to evaluate the vasular system. It is possible to perform angiograms for different parts of the body, such as the left and/or right heart, the aorta, selective veins such as the subclavian, the renal artery and peripheral angiograms (the limbs) as well.

LookingforAdvancedDs: Artery ds is within artery walls & does not show on angiograms. Angiogram means blood picture; pictures show a 2d image, still or motion, of dye added into the blood, so that the dye/blood column shows on x-ray. After artery disease very advanced, ruptures of artery wall lining occur shedding debies & inducing clots which narrow the artery opening. Angiograms can detect advanced disease problems.
