目的利用红外热成像技术评价糖尿病(DM)患者下肢末端供血状况.方法红外热成像仪分别采集60例临床明确诊断的DM患者以及20例健康中老年人下肢肢体的红外热成像图.以踝关节及跖趾关节为两个主要标志线,将下肢肢体分为4个区;以不同温度刻度伪码条对应从低温到高温相应的红外热像图,对所有采集的160个肢体进行末端供血状况评判.结果下肢末端供血状态良好者,其红外热像表现为1~4区呈黄色温区或红色热区表达;末端血循环欠佳主要表现在1区~2区之间,红外呈现绿色的凉区表达;下肢动脉闭塞主要表现为起始于3区及4区,红外表达主要呈现蓝色冷区.两组红外检测结果进行卡方检验,差异有统计学意义(χ2=13.275,P<0.01).结论红外热成像检测技术能灵敏地反映DM患者下肢末端的供血状况,是一种理想的无创便捷的新型评价工具.

Objective To evaluate lower extremity blood-supply among patients with diabetes mellitus (DM) by utilizing infrared thermal imaging technique.Methods Infrared thermal images of 60 patients with clinically diagnosed DM and 20 normal middle-aged and aged subjects were captured by infrared thermal imaging device.With ankle joint and metatarsophalangeal joint as two major landmarks,the lower limb was divided into four zones.As infrared thermal images from low to high temperature were correspondent with different pseudo code of temperature scales,lower extremity blood-supply of 160 lower limbs was evaluated.Results The infrared thermal imaging of the well blood-supplied lower extremity was expressed by yellow-warm or red-heat color in all 4 zones.While the poor blood-supply to extremity was green-cold color in zone 1 and/or zone 2.And the end-arterial occlusion of lower extremity was mainly expressed by blue-cool color originating from zones 3 and 4.The results of infrared detection of the two groups were significantly different by chi-square test(χ2=13.275,P<0.01).Conclusion Infrared thermal imaging technique can sensitively reflect the lower extremity end blood-supply of DM patients and can be a new ideal,non-traumatic,convenient evaluation tool.
