What is the difference between radial and femoral angiography?

Dr. John C. Lipman, MD
Vascular & Interventional Radiologist

Angiography is the study of arteries and/or veins. Femoral and radial angiography refer to the point of entry in the body where the procedure is performed. For femoral angiography the site of entry is typically the right common femoral artery, although either can be used. For radial angiography, the entry point is the radial artery and depending on the type and location of the target organ to be studied, the left or right artery can be used. For blood vessels being studied below the diaphragm, the left radial artery is standard due to anatomic considerations.
