From: MRI of Whole Rat Brain Perivascular Network Reveals Role for Ventricles in Brain Waste Clearance
Perivascular tracer labeling and PVS connections between ventricles and brain parenchyma in individual image slices from the 3D image stack. (A) Ring enhancement around penetrating thalamic blood vessels (red arrows) showing the presence of tracer in PVS. Also shown are PVS around anterior choroidal artery (yellow arrow) connecting the lateral ventricle (green arrow) to the ventral brain surface. (B) Ring enhancement around vessels in cortex (red arrows) and PVS connections between lateral ventricle (green arrow) and caudate/putamen (yellow arrow). (C) Ring enhancement around the basilar artery (red arrow) and PVS around a paramedian branch of the basilar artery (yellow arrow head) connecting to the fourth ventricle (green arrow). (D,E) Enlarged sections of (A,B) outlined in white showing ring enhancement around blood vessels.
