Fig. 1From: Effects of adenosine and regadenoson on hemodynamics measured using cardiovascular magnetic resonance imagingSchematic of the study design. SAX = short axis projection; SSFPs = steady-state free precession sequences. For the purposes of analysis, hemodynamic, volumetric, and ejection fraction results obtained at the 15 min point following adenosine administration were used as the baseline values for regadenoson administrationBack to article page
