The distal forelimbs of 10 clinically normal horses with hair clipped on 1 limb were thermographically scanned before and after exercise. The thermal patterns, temperature distribution, and temperature changes after exercise were determined and compared with those of 8 horses with podotrochlosis. Clipping the hair did not cause changes in the thermal patterns, but the clipped limbs were warmer than the unclipped limbs. The temperature of the limbs of horses with podotrochlosis did not increase as much after exercise as did the limbs of normal horses. The failure of skin temperature increase correlated with the radiographic evidence of enlarged vascular foramina in the navicular bone. Because the failure to increase skin temperature after exercise is the result of low blood flow, the enlarged vascular foramen can be related to a state of low blood flow.
对10匹临床正常的马进行热成像扫描，这些马的1条肢体被剪毛，分别在运动前后扫描其前肢远端。确定了运动后的热模式、温度分布和温度变化，并与8匹患有蹄骨环枢关节病的马进行比较。剪毛并未引起热模式的变化，但被剪毛的肢体比未剪毛的肢体温度更高。患有蹄骨环枢关节病的马的肢体在运动后温度升高幅度不如正常马的肢体。皮肤温度未能升高与舟状骨血管孔扩大的影像学证据相关。由于运动后皮肤温度未能升高是血流不足的结果，血管孔扩大可能与血流不足状态有关。
