糖尿病是以血糖升高为主的伴有多系统并发症的慢性代谢性疾病.糖尿病足(DF)是糖尿病严重的并发症,影响长期的生活质量.目前检查金标准是数字减影血管造影,同时可以进行血管内成形术,但是即使成功的血运重建后,部分患者仍然溃疡愈合失败而导致截肢.因此,运用影像学方法早期检测糖尿病足部灌注情况,评估组织愈合潜力对治疗DF具有重要指导意义.除常规检查方法外,越来越多的影像新技术运用到DF微循环的检查中,从而为临床进行早期预防和干预、制定诊疗计划、监测疾病发展、评估新型治疗技术如血管生成细胞治疗、干细胞移植等的功效.%Diabetes mellitus is a chronic metabolic disease with multiple systemic complications .Diabetic foot ( DF) is a serious complication of diabetes and affects long-term quality of life .The current gold standard is digital subtraction angi-ography,while angioplasty can be performed ,but even after successful revascularization ,some patients still suffer ulcer dis-union and amputation .Therefore,the early imaging methods to detect diabetic foot perfusion ,assessment of tissue healing potential has great significance .In addition to routine examination methods , more and more new imaging techniques are applied to detect DF microcirculation ,so as to realize early clinical prevention and intervention ,make treatment plan ,moni-tor disease development ,assess new treatment techniques such as angiogenesis cell therapy and stem cell transplantation .
