Comparison of Three-Dimensional Micro-CT Angiography of Cervical Spinal Cord between Two Contrast Agents

Figure 4

Vasculars of the cervical spinal cord at high-resolution micro-CT scanning. The intact view of 3D microvasculature following the barium sulfate (a) and lead oxide (b) perfusion. Lateral view of 3D microvasculature following the barium sulfate (c) and lead oxide (d) perfusion. Cross-sectional 3D reconstruction of 100 slices in the middle part of the scanned spinal cord following the barium sulfate (e) and lead oxide (g) perfusion. 2D micro-CT image of the cervical spinal cord microvasculature in the barium sulfate group (f) and lead oxide group (h). The bar graphs showing VV/TV, V.Dm, V.N, SMI, Conn.D, V.Sp, percentage, and volume of vessels (i–p). There was no significant difference in VV/TV and V.Dm between the two groups. V.N, SMI, and Conn.D of barium sulfate group were higher than those of the lead oxide group, with V.Sp less than that of lead oxide group. denotes between the barium sulfate and lead oxide groups.
