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 vs. FMD lesions in older patients, and may thus be preferred to MRA.[2]

  • the disadvantages are exposing patients to irradiation, nephrotoxicity, and allergic reactions to iodinated contrast medium.
