Fibromuscular dysplasia CT

Overview

Computed tomography angiography (CTA) has really excellent diagnostic exactness for FMD of the renal arteries. CTA may use in the diagnosis of FMD of the cervicocephalic arteries and to find associated intracranial lesions.

Computed Tomography Angiography

CTA and MRA, both have good sensitivity and specificity in detecting FMD-related RAS lesions, but due to better spatial resolution of CTA than MRA, CTA is the recommended imaging technique to confirm the diagnosis of renal artery FMD.^[1]

In addition, CTA can detect distal lesions, small calcifications, and determining discrimination of atherosclerotic versus FMD lesions in older patients, and may thus be preferred to MRA.^[2]

The disadvantages included
- Allergic reactions to iodinated contrast medium.
- Nephrotoxicity
- Exposing patients to irradiation
