Figure 6From: Measuring aortic pulse wave velocity using high-field cardiovascular magnetic resonance: comparison of techniquesIntra-observer variability. Bland-Altman (up) and regression analysis (down) are shown for transit-time (left), cross-correlation (middle), and flow-area (right) methods on the patients' cohort. The transit-time and cross-correlation methods result in better agreements than the flow-area method.Back to article page
