Figure 7.
Two-sided t-test results (not Bonferroni corrected) from the block design paradigm shown with a lower threshold of p < 10−3 and a color scale saturation level of p < 10−8. All block designs were 20 s per period, and γB1lock = 40 Hz. T-test results are overlaid on a high resolution Turbo Spin Echo (TSE) image which allows visualization of the current dipole’s wires. a) 118 μA applied current, b) 11.5 μA applied current, c) 5.6 μA applied current. The statistical parametric map is overlaid over a high-resolution fast spin-echo image of the phantom to visualize the location of the dipole wire.
