From: Mapping of brain tissue hematocrit in glioma and acute stroke using a dual autoradiography approach
(a) Representative images of MRI anatomical images and of red blood cells (Vrbc), plasmatic (Vp), vascular volume (Vv) and tissue hematocrit (tHct) maps obtained by autoradiography for the Control, Hemodilution and EPO groups. Note that the MRI anatomical image for the Hemodilution group is that of a template. For each animal, all images are coregistered. The green, red and blue lines illustrate the automatic delineation of the cortex, white matter and striatum region of interest, respectively. The white arrows point towards a large vessel observed across each ARG maps. (b) tHct values measured in each region of interest using the autoradiography (ARG) or the gamma-well counting (GWC) approach. Mean ± SD. (c) Scatter plot of the correlation between the tHct values obtained using the ARG and the GWC techniques. Data from the Hemodilution (triangle), Control (diamond) and EPO (square) are pooled (one symbol represents one animal).
