Blood vessels without X-rays.
Aneurysm, narrowed vessels.
Remove all metal. Tell staff about pacemakers, implants, metal fragments, kidney disease or pregnancy. Ear protection is given; tell staff if you are claustrophobic.
No ionising radiation (magnetic field and radio waves). Safe in pregnancy (MRI: discuss in the first trimester; avoid gadolinium contrast unless essential).
30 to 60 minutes. General information, not a diagnosis. Results must be interpreted by a qualified health worker.
