Figure 1From: Quantification of transmural perfusion gradients by high-resolution MR versus fractional flow reserve for the assessment of coronary artery stenosisLeft: example of a patient showing inferior subendocardial ischemia. Right: the gradientogram plot allows measurements of radial extent, temporal persistence, area, peak and average intensity as well as strength of the transmural perfusion gradient (see the text for details on the units of measurements).Back to article page
