I’ve edited a MATLAB code that produces a T1 map from two flip angles. I have MRI slices that are 5×170 slices for 5 different flip angles (2,10,11,12,13). I converted them into .nii files and performed the matlab code which worked. It displays 2 rows of T1 maps for each set of angles. The first row of images represent the T1 values from the initial iteration, which are essentially the initial guesses of the T1 relaxation times. These values are based on the raw data without the iterative refinement process applied. The second row of images represent the T1 values after the iterative refinement process has been completed (after 10 iterations). These values are more accurate and have been corrected for residual T1 saturation effects through the iterative process. However, my T1 maps that came out have a lot of noise especially in the background and don’t look like a normal T1 map, can anyone help me understand why this might be?I’ve edited a MATLAB code that produces a T1 map from two flip angles.
