Measuring Thickness of Middle Ear Mucosa Using MRI and CT Imaging versus Histopathology

Figure 4

Boxplot of mucosal thickness by CT Imaging. Findings by CT also reveal that DEX treated chinchillas had less MT thickness when compared to the other groups. While the overall trend is comparable to the MRI and Histology results, the CT findings are not statistically significant at an 𝛼=0.05 level due to the small sample size (𝑁=14, 𝜒²=0.9762, 𝑃-value=0.6138). CT measures of MT were based on mucosal volume (mm³).
