Fig. 5From: Influence of hydration status on cardiovascular magnetic resonance myocardial T1 and T2 relaxation time assessment: an intraindividual study in healthy subjectsExemplary region-of-interest (ROI) placement in a 26-year-old healthy subject after fasting. Midventricular section T1 and T2 map are provided. Subendocardial (green) and subepicardial (yellow) contours were drawn carefully throughout the entire midventricular myocardium. ROI placement was performed within the myocardium to avoid confounding partial volume effects of the blood pool and chemical shift artifacts. Mean T1 relaxation time was 933 ms and mean T2 relaxation time was 48.5 msBack to article page
