Dots represent absolute MBF in ml/g/min with the dual bolus (X-axis) and the single bolus analysis technique (Y-axis) during adenosine stress perfusion. NSP MR sequence (blue dots) results in higher MBF values with the SB than with the DB analysis technique (blue line shifted to the left of the red equality line), and this is even more the case for the SP MR sequence (green dots and line). In the absence of a saturation effect, theoretically the MBF value calculated with the DB and SB analysis technique would be the same (red equality line).
