Extracellular volume fraction (ECV) measurement is
expected to reflect the degree of fibrosis in dilated
cardiomyopathy. The right ventricular (RV) blood T1
value could be measured in cases of flow artifacts or
turbulence in the left ventricular (LV) cavity, but the
RV blood T1 and the effect of blood T1 value on ECV
remain unknown. The RV blood T1 was shorter than the LV
blood T1, but the ECV of myocardium, including scarring,
was not affected by the ventricle where blood T1 was
measured. The measurement in the RV is allowed to
estimate myocardial ECV in some patients.
