FIG 1. Manual contouring of the hematoma.
A, On the T2-weighted echo planar image (b = 0 mm2/s) on which the hematoma appears largest, the outer limit of the region of interest corresponded to the T2-hypointense ring.
B, The region of interest is copied on the diffusion-weighted image (b = 1000 mm2/s).
C, Mean absolute ADC values are computed in the region of interest. Mirror region of interest is placed on the contralateral hemisphere to compute the rADC.
