Figure 2From: Measuring aortic pulse wave velocity using high-field cardiovascular magnetic resonance: comparison of techniquesTransit-time method for calculating PWV. Velocity curves (right) from a volunteer scan are computed at two distant cross sections (middle) along the descending aorta (left). PWV = Δx/Δt, where Δx is the distance between the two locations and Δt is the time difference between the two velocity curves.Back to article page
