Fig. 4.
Average T2 and T2* values were obtained from ROIs at the center of the tubes shown in Fig. 2, and a linear regression was performed to test the accuracy of the proposed T2 and T2* mapping scheme against reference results. The fit results indicated good accuracy: Slope of 0.99/0.94, intersect of 1.61 /1.24 ms and R2 = 0.998/0.998 for T2 and T2*, respectively.
