Projection images detected by ACI (n = 8) and PCI (n = 8). (a) Projected ACI image. (b) Projected PCI image. (c, d) Comparison of the density distributions of the cross-sectional profiles marked in (a) and (b). (c) The attenuated signal decreased significantly, indicating the location of the anterior spinal artery (ASA) and posterior spinal vein (PSV) marked in (a). (d) The fluctuations in the line profiles in (a) and (b) are frequent in areas of the spinal cord enriched with an intramedullary artery (IA) network. (a, b) Scale bar: 100 µm. |
