Imaging of Renal Arteries

Imaging Technique	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
Angiography (Gold Standard)	100 (31/31)	100 (16/16)	100 (31/31)	100 (16/16)
US	28 (7/28) p = 0.003	100 (13/13) p = 0.6	100 (7/7) p = 0.6	41.9 (13/31) p = 0.06
MRA	62.5 (5/8) p = 0.3	100 (1/1) p = 0.8	100 (5/5) p = 0.6	40 (2/5) p = 0.2
CTA	84.2 (16/19) p = 0.4	70 (7/10) p = 0. 4	84.2(16/19) p = 0.4	70 (7/10) p = 0.4

p values are obtained from a comparison with Angiography

PPV positive predictive value, NPV negative predictive value, US ultrasound, MRA magnetic resonance angiography, CTA computed tomography angiography
