T2' is another MRI parameter that reflects solely to the magnetic inhomogeneity and shows high correlations to LIC, T2 and T2*. We compare liver T2' obtained from ROI and pixel based method by three curve-fitting models, mono-exponential, offset and truncation model. Fifteen β thalassemia major patients were study. Results showed that ROI based method with offset curve fitting model potentially provided no significantly difference outcomes to those of pixel based method for liver T2 measurements.
