MRA
Author
Assistant
Introduction
Used to evaluate the brain?s arterial anatomy
Indications (study of / in suspicion of):
Aneurysm
Stenosis/occlusion related to stroke, or carotid stenosis
Dissection
Arteriovenous malformations
Done without contrast (MRA ? brain), hence it is a good alternative to CT angiography for patients on whom contrast cannot be used. However, MRA – Neck requires gadolinium contrast.
