Cooling of the skin over the medial supraorbital region in 80% of patients who have an occlusion or severe stenosis of a carotid artery can be demonstrated by facial thermography. Minor stenotic lesions in the carotid arteries do not produce characteristic thermographic changes, while thermography is of no help in the diagnosis of vertebrobasilar arterial disease.Thermographic changes suggestive of carotid arterial lesions are found occasionally in patients whose angiograms are normal, owing to variations in the size of the frontal sinuses, or factors such as fever or inflammatory lesions.It is suggested that facial thermography is of value in the preliminary investigation of patients with occlusive cerebrovascular disease.
通过面部热成像检查可发现，80%患有颈动脉闭塞或严重狭窄的患者眶上内侧区域的皮肤会出现降温现象。颈动脉轻度狭窄病变不会产生特征性热成像变化，而热成像对椎基底动脉疾病的诊断并无帮助。由于额窦大小的差异、发热或炎症性病变等因素，血管造影正常的患者偶尔也会出现提示颈动脉病变的热成像变化。有人认为面部热成像在闭塞性脑血管疾病患者的初步检查中具有一定价值。
