Axial transverse FLAIR image (1.a) through centrum semiovale showing hyperintensity within acutely infarcted whole territory of the right middle cerebral artery (MCA), and corresponding global R1-mapped image (1.b), lipids R1-mapped image (MOBILE) (1.c) and R2*-mapped image (1.d) in a similar slice location. Image 1.e: overlay of the two ROIs (right-sided contour of infarction and left-sided mirrored one) from the MOBILE map (1.b) on the FLAIR image (1.a). Images 1b-1e have been smoothed using the ‘Gaussian Blur’ function (radius of 2 pixels) of the GIMP software (GIMP 2, GNU Image Manipulation Program, GPLv3). Histograms of global R1 (1.f), lipids R1 (1.g) and R2* (1.h) of the same patient demonstrating significant shift of the medians to lower values for the stroke area. Differences of 0.111 s-1, 0.536 s-1 and 6.09 s-1 are observed for global R1, lipids R1 and R2*, respectively.
