Fig. 3From: Measurement of pulse wave velocity in normal ageing: comparison of Vicorder and magnetic resonance phase contrast imagingRelationship of Vicorder to phase contrast MRI (a) (y = 0.345x + 3.45, R2 = 0.073, R = 0.271 P < 0.05), and Bland Altman plot of the two techniques (b). On average Vicorder values are 1.6 m/s greater than MRI values. PWV: pulse wave velocity, and SD: standard deviationBack to article page
