From: A novel model of ischemia in rats with middle cerebral artery occlusion using a microcatheter and zirconia ball under fluoroscopy

Figure 4

(A) Three sizes of zirconia ball. From left to right: 0.2 mm, 0.4 mm and 0.5 mm in diameter. The zirconia ball used in the stroke model was 0.4 mm in diameter. (B) Fluoroscopy shows the anterior cerebral artery-middle cerebral artery bifurcation that was selectively embolized by one zirconia ball 0.4 mm in diameter (arrowhead). The site of embolization can be easily identified during fluoroscopy because of the high visibility of zirconia ball.
