A computed tomography angiogram (CTA) or a
magnetic resonance angiogram (MRA) may be an option
instead of an angiogram. Each of these tests is less invasive than a standard
angiogram. Some MRA tests and all CTA tests require an injection of dye. A CTA
also involves radiation exposure. Some doctors may want results
from a standard angiogram before doing surgery to treat a damaged or abnormal
For people with kidney problems,
dehydration, steps are taken to prevent kidney damage.
Less dye may be used or more fluids may be given before, during, and after the
test. If you have a history of kidney problems, other blood tests (creatinine,
blood urea nitrogen) may be done before an angiogram to make sure that your
kidneys are working well.
In rare cases,

help plug the hole in the vessel and stop the bleeding. The substance used to
plug the hole in the vessel is normally absorbed by the body over several
