Blood T1 value is measured to calculate extracellular
volume of the myocardium, which correlates with the
severity of fibrosis. The effects of location of ROI,
cardiac function, and flow on the blood T1 value are
concerned. We compared the blood T1 value between the
left ventricle and right ventricle or aorta at a 1.5 T
and 3.0 T. The relationship between the blood T1 value
and heart rate, ejection fraction, or jet induced by
valvular regurgitation was assessed. Blood T1 value can
be measured at both ventricle using postcontrast
Look-Locker MRI without concern about cardiac function
and intraventricular flow.
