Averaged VBR of all volunteers.

Averaged VBR over all stations and both legs for the ten volunteers. In the far right column, the average over all volunteers is given. Standard deviation of the signal intensities inside the measured ROIs were used as error. Error values in this table were calculated via rules for propagation of uncertainty. The QISS sequence led to the lowest VBR in all cases, whereas UGRE performed best. Overall, UGRE reached relevantly higher values than GRE.
