“…Four cut-off values of m-IB with THI had high sensitivity, specificity, and accuracy for discrimination of each level of myocardial fibrosis severity. Previously the usefulness of IB for tissue characterization has been discussed in many studies [7,8,9,14,15,16,17,18,19, 22], but we first documented cut-off values of IB for the quantification of myocardial fibrosis in DCM. We think that combined m-IB and THI is much useful compared with IB alone and is practically acceptable method in evaluation of severity of myocardial fibrosis in clinical settings.…”
