Overview
- Imaging modilities are the methods for diagnosing FMD.
- Duplex ultrasonography, accompanied by computed tomographic angiography (CTA), and magnetic resonance angiography (MRA), are imaging techniques for detecting FMD lesions but the gold standard remains catheter-based angiography.
Diagnostic Study of Choice
Overview
- Arteriography remains the gold standard
Angiography with contrast will show a characteristic "string of beads" morphology in a vessel affected by FMD.
Study of choice
- Catheter-based angiography is the gold standard test for the diagnosis of renovascular fibromuscular dysplasia.
- The following result of Catheter-based angiography is confirmatory of fibromuscular dysplasia:
- Multifocal FMD: Imaging may reveal the classic string of beads appearance. (image 1)
- Focal FMD: Imaging may reveal a concentric, smooth, band-like focal stenosis or a tubular stenosis (image 2)
- Extreme arterial tortuosity. This is most common in the carotid, vertebral, and coronary arteries (image 3)
Arteriography
