Transverse relaxation time T2 of the right ventricle (RV) wall is not a well known quantity and its value has only been reported by few studies, most likely due to the thin right ventricle wall avoiding accurate measurements. In this study, T2 of the RV inferior wall was measured in end-systolic rest, when RV wall is thickened, using a recently described adaptive method and a double inversion recovery fast spin echo sequence on a 1.5T scanner. T2 values of the RV in healthy volunteers were significantly longer than those of the LV which is in concordance with other studies.
