摘　　要：目的评价足底筋膜损伤的MRI诊断价值。方法回顾性分析11例经手术病理和临床随访证实足底筋膜损伤患者的MRI与临床资料,总结MRI表现特征。结果足底筋膜损伤的MRI表现有4种类型,(1)急性筋膜炎:T_2WI、Stir足底筋膜内斑片状高信号,筋膜周围软性组织呈高信号改变。(2)慢性筋膜炎:T_1WI足底筋膜呈纺锤形增厚,信号增高,筋膜附着部跟骨见骨性突起或局灶性皮质缺损。(3)筋膜完全断裂:T_1WI、T_2WI、Stir筋膜连续性中断,断裂部位呈高信号改变。(4)筋膜部份断裂:T_1WI、T_2WI、Stir筋膜连续性部份中断,断裂部分增厚,呈高信号改变。结论 MR是诊断足底筋膜损伤的最好检查方法 。Objective To investigate the value of MRI in the diagnosis of plantar fascia injury. Methods MRI and medical records were retrospectively analyzed in eleven cases with histologically and clinical fowllow - up proved plantar fascia injury. MRI morphology and signal characteristics were summarized. Results MRI features of the plantar fascia injury were divided four types. （ 1 ） Acute plantar fasciitis ： the plantar fascia showed the spotted high signal intensity and the surrounding soft tissue in the region of the plantar fascia was the high signal intensity on T2 WI and stir. （2） Chromic plantar fasciitis ： the plantar fascia showed shuttle thick and increasing signal intensity on T1WI, T2WI, Stir. The calcaneas showed the spur and focal cortical defect at the plantar fascia insertion. （3） The complete tear of the plantar fascia： the continuity of the plantar fascia was rupture, the region in the rupture was high signal intensity on T1WI, T2WI, Stir. （4）The partial tear of the plantar fascia： the continuity of the plantar fascia was partial rupture, the region in the rapture showed thick and high signal intensity on TI WI, T2 WI, Stir. Conclusion MR is the best way in the diagnosis of the plantar fascia injury.
