Understanding the reasons behind symptoms such as dizziness, fatigue, festinating gait, and forgetfulness is part of the goal of MRA scans. An MRA scan, or magnetic resonance angiography, is performed in conjunction with an MRI (magnetic resonance imaging). However, the difference is that an MRA scan uses the MRI machine but produces a more detailed analysis of the blood vessels rather than their surrounding organs and tissues. If a patient experiences symptoms relating to possible blocked or narrowed blood vessels, a doctor may recommend the patient gets an MRA scan. Both MRA and MRI procedures are painless and non-invasive and are used to diagnose many different conditions and abnormalities within the body.
