Fig. 1From: Detection of increased pyruvate dehydrogenase flux in the human heart during adenosine stress test using hyperpolarized [1-13C]pyruvate cardiovascular magnetic resonance imagingOutline of study design. The duration of each study visit was < 2 h. CMR cine imaging typically lasted 45 min and metabolic imaging lasted 5 min at rest and 6 min during adenosine stress test. The mean time interval between rest and stress study was 5 ± 3 monthsBack to article page
