Figure 3From: Evaluation of the middle cerebral artery occlusion techniques in the rat by in-vitro 3-dimensional micro- and nano computed tomography Macrosphere Model. Macroscopic image (A, B) of macrospheres present in the circle of Willis (A) and in the circle of Willis, the anterior cerebral artery and the middle cerebral artery (B). Micro-CT maximum intensity projection (C, D) also demonstrate the macrosphere perfusion territories. Nano-CT imaging (E, F) demonstrate collateral perfusion with contrast-enhanced afferent and efferent vessel perfusion.Back to article page
