Fig. 2From: Feasibility of cardiovascular magnetic resonance derived coronary wave intensity analysisFor derivation of pressure data (top panel), a cross sectional plane was identified 35Â mm above the aortic valve plane. A high temporal resolution gradient echo sequence was used to acquire aortic areas throughout the cardiac cycle and these were used to derive the central aortic pressure during the cardiac cycle.
