Table 4. Fitted results from phantom measurements a MSE sequence with different FAs as used in the sequence protocol (see Supporting Information, S1 Dataset: MSE datasets) and different fitting methods.
Single spin echo sequence yielded a mean T2 of 67.7 ± 0.60ms. T2 and dT2 relate to the mean and standard deviation over 3 ROIs within the phantom for each measurement.
