The purpose of this study is to investigate an influence of cholesterol on the near-infrared images of blood vessels. In this study, the near-Infrared images of lateral caudal veins in a male Wistar rat were captured while pressing rat's tail by a tail cuff. The ten high cholesterol rats and the ten normal rats were used for this study. The total cholesterol density of the high-cholesterol rat was about 3.5 times as large as that of the normal rat significantly (p<0.01). As the pressure level increased, the change in the luminance of the near-infrared images increased in both rats. This result shows congestion in the lateral caudal veins compressed by the tail cuff. In 80mmHg and 100mmHg pressure level, the change in the luminance of the near-infrared images in the high-cholesterol rats was larger than that in the normal rats significantly (p<0.05).
