Does quantitative measurement of myocardial fibrosis via T1 mapping correlate with myocardial biopsy measurements?
T1 mapping demonstrates a favorable correlation with histologic biopsy for quantifying myocardial fibrosis, supporting its use as a non-invasive imaging biomarker.
The quantitative measurement of myocardial fibrosis via T1 mapping is associated with a favourable overall correlation with the myocardial biopsy measurements. Further studies are required to determine the calibration of the T1 mapping results for the biopsy findings of different cardiomyopathies.
