Fig. 7.From: Inflammogenic effect of polyacrylic acid in rat lung following intratracheal instillation3D micro-CT imaging following intratracheal instillation and how to view the CT image and the relationship between the CT image and the anatomical position. At 3Â days: A control group. B 0.2Â mg-exposure group. C 1.0Â mg-exposure group. At 1Â month: D control group. E 0.2Â mg-exposure group. F 1.0Â mg-exposure group. At 3 monthss: G control group. H 0.2Â mg-exposure group. I 1.0Â mg-exposure group. Diffuse or centrilobular infiltration (red arrow) in both lungs was presented at 3Â days and 1Â month after the exposure in a dose-dependent manner. The finding was persisted during 1Â month and improved at 3Â months after the exposure. The relationship between the CT image and the anatomical position is shown at JBack to article page
