Quantitative T2 mapping is required for the characterization of myocardial tissue. The superior performance of the black-blood preparation compared to the bright-blood data for myocardial T2* measurements in iron-overloaded thalassemia has been reported. Therefore the aim of this work was to compare the performance of the monoexponential and offset mapping algorithms for T2 quantification based on T2-prepared steady-state free precession imaging technique with and without black-blood preparation. The preliminary results obtained from 5 subjects showed that the offset model provide a more robust T2 decay curve fitting for myocardial T2 mapping compared to the simple monoexponential model in both bright- and black-blood data.
