Fibromuscular dysplasia MRI

Overview

Magnetic resonance angiography (MRA) in comparison with DUS and CTA is less preferred, due to an inadequate spatial resolution in the branch vessels, and pseudobeading features from artifact impact. However, MRA can be useful for detecting aneurysms and dissections.

Magnetic Resonance Angiography

Magnetic resonance angiography (MRA) in comparison with DUS and CTA is less preferred, due to an inadequate spatial resolution in the branch vessels, and pseudobeading features from artifact impact. However, MRA can be useful for detecting aneurysms and dissections.^[1]

According to AHA guideline, MRA of the head should be performed in all patients with cervicocranial FMD. DUS may reveal an irregular stenosis of the carotid or vertebral arteries compatible with FMD. However, CTA and MRA are likely to perform better, especially because FMD usually affects the middle and distal portions of the carotid and vertebral arteries, which are less accessible to DUS. Moreover, CTA and MRA have the advantage to allow the detection of associated intracranial aneurysms.^[2]
