Louis R, et al. - Comparative analysis of the efficacies of different imaging modalities [Doppler ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI)] which can allow for earlier and improved detection of pediatric fibromuscular dysplasia (FMD) was carried out in patients with non-syndromic non-inflammatory renovascular hypertension enrolled in the U.S. FMD Registry maintained at the University of Michigan. They believed an anatomical mapping of the location of lesions could help determine the best treatment modalities. Relative to angiography, significantly less sensitivity was shown by US imaging, compared to which magnetic resonance angiography (MRA) displayed better sensitivity. Overall, any child suspected of having renovascular FMD should undergo angiography as part of the initial work-up, irrespective of the findings seen on US, MRA, or computed tomography angiography (CTA).
