Figure 4
XFCT image of formalin-fixed (ex vivo) mouse brain set within an acrylic cell filled with formalin (a, b, c), and autoradiogram with 125I-IMP (d). Cerebral perfusion in the cortex, hippocampus and thalamus are well depicted in the 0.25 mm in-plane spatial resolution image (a), whereas the hippocampus was not clearly separated from the thalamus in the 0.5 mm in-plane spatial resolution image (b). The XTCT image shows only the margin of the acrylic cell's wall, while the inner area including the brain and formalin solution is homogeneous (c). Autoradiogram of the brain of a mouse injected with 125I-IMP (d). |
