摘　　要：目的探讨糖尿病足溃疡的超声造影灌注动态变化。方法研究16例糖尿病足溃疡的常规及超声造影图像,分析其造影增强的图像特点,并对部分病例进行病理检查。结果注射SonoVue后,16个病灶超声造影动脉期清晰显示随时间推移呈缓慢增强,平均开始增强时间为(30.02±2.35)s,达峰时间为(37.54±4.13)s。5例呈均匀增强区域,11例呈周边较均匀增强,内部可见片状无增强区域,即液化坏死区。造影提示病灶范围较常规超声范围大。结论超声造影能有效地对糖尿病足溃疡进行范围评估和治疗随访。Objective To investigate contrast-enhanced ultrasound imaging features of diabetic foot ulcers.Methods Sixteen patients with diabetic foot ulcers underwent conventional and contrast-enhanced ultrasound examinations,and the features of contrast-enhanced ultrasound imaging were analyzed.Pathological examination was also carried out in some cases.Results Contrast-enhanced ultrasound showed slow enhancement in the artery phase in the 16 ulcers after administration of SonoVue.The mean time of initial enhancement was 30.02±2.35 s,and the mean time for the occurrence of peak enhancement was 37.54±4.13 s.In 5 cases a homogeneous enhancement pattern was clearly displayed,and in the other 11 cases,a pattern of homogenous peripheral enhancement with non-enhanced patches within the ulcers was found.Contrast-enhanced ultrasound showed a greater ulcerous area than conventional ultrasound.Conclusion Contrast-enhanced ultrasound is a valuable means for evaluating the ulcerous area and the treatment efficacy for diabetic foot ulcers.
