Good Positive and Negative Likelihood Ratios

Finding +LR-LR Comments, Study
Magnetic Resonance Angiography Edit 500

sensitivity much lower for FMD (which affects more distal portion of the artery). In another study, sens / spec was only 62% / 84%

Study: AJR Am J Roentgenol. 1999;173(5):1279. PMID 10541105

Kidney Int. 1995;48(4):1332. PMID 8569096

CT angiography Edit 16.30

sensitivity lower in another series with many FMD patients (see comments in MRA finding) - only 28% in patients with FMD

Study: Radiology. 1995;196(3):667. PMID 7644627

Ann Intern Med. 2004;141(9):674. PMID 15520423
