ABSTRACT
Objective To assess the single-exponential and dual-exponential fitting methods of MR T2-Map, and to get T2 value of each pixel. Methods Single and dual-exponential methods with linear fitting and non-linear regression fitting techniques were used for a series images with different TE; then T2-Map images were achieved. T2-Map software was realized on MATLAB and it had the function of compute, display, save and so on. Results T2-Map software with single-exponential and dual-exponential fitting methods was achieved, able to calculate T2 value of tissues everywhere and form the T2-Map image. Conclusion Single-exponential T2-Map method is convenient, having obvious merit-high speed, but can not show the area with obvious different contents very well. However, dual-exponential fitting method can deal with this question with providing different T2 values, thus is accurate with the sacrifice of costing too much time. Dual-exponential fitting method of T2-Map is a beneficial supplement to single-exponential method.
