Retroactive and proactive SLAM in normal brain. (a) MRI of normal brain, overlaid with the CSI grid and segmented into four compartments post MRS acquisition: (1) user-defined area; (2) ‘rest of the brain’; (3) scalp; and (4) background. (b–d) 2D CSI (blue) and 2D SLAM spectra (red and green) acquired from the four compartments. The red SLAM spectra were acquired in a proactive scan using data 14 times faster than CSI. The green SLAM spectra were reconstructed retroactively from a subset of 1/14th of the CSI data.
