目的:探讨糖尿病足(diabetic foot,DF)的临床及影像学表现。方法:回顾性分析62例DF患者临床及影像资料、临床及MRI影像特点。结果:(1)临床结果:足部皮肤溃疡59例,足部胼胝7例,足部畸形4例;31例CT血管造影术提示下肢动脉硬化,其中9例足背动脉闭塞。平均病程为9.18年,最长病程40年。(2)影像检查结果:28例诊断为骨髓炎,21例骨髓水肿,8例夏科氏关节合并感染,9例骨髓炎伴脓肿形成,4例伴窦道形成。结论:MRI能够清晰显示DF足部骨质及软组织病变范围及程度,结合MRI影像特征和临床分析,有利于监测DF病变发展及临床预后。
Objective: To investigate the clinical and imaging features of diabetic foot (DF). Methods: Retrospective analysis of 62 cases of DF patients with clinical and imaging data, clinical and MRI features. Results: (1) Clinical results: There were 59 cases of foot skin ulcer, 7 cases of foot callus and 4 cases of foot deformity. 31 cases of CT angiography showed lower extremity arteriosclerosis, including 9 cases of dorsalis pedis artery occlusion. The average duration of disease is 9.18 years, the longest duration of 40 years. (2) The imaging examination results: 28 cases were diagnosed as osteomyelitis, 21 cases of bone marrow edema, 8 cases of Chaco’s joint infection, 9 cases of osteomyelitis with abscess formation, 4 cases with sinus formation. Conclusion: MRI can clearly show the scope and extent of DF bone and soft tissue lesions. Combined with the features of MRI and clinical analysis, it is helpful to monitor the development of DF lesions and clinical prognosis.
