The clinical presentation of plantar fasciitis may be mimicked by a number of other painful heel conditions. Thus, magnetic resonance (MR) imaging was used to develop objective morphologic criteria to establish a diagnosis of plantar fasciitis in eight patients. Sagittal T1-weighted and coronal intermediate and T2-weighted images of symptomatic and asymptomatic feet were obtained; additional sequences were used for symptomatic feet. Maximum thickness of the plantar fascia was significantly increased (P less than .0001) in patients with plantar fasciitis (sagittal, 7.40 mm +/- 1.17, and coronal, 7.56 mm +/- 1.01) compared with age- and sex-matched volunteers (sagittal, 3.22 mm +/- 0.44, and coronal, 3.44 mm +/- 0.53) and young male controls (sagittal, 3.00 mm +/- 0.8, and coronal, 3.00 mm +/- 0.0). Furthermore, nine of 10 feet with plantar fasciitis had areas of moderately increased signal intensity in the substance of the fascia. MR imaging may provide an objective assessment of the morphologic changes associated with plantar fasciitis, as well as assist in excluding other causes of heel pain.
足底筋膜炎的临床表现可能与其他多种足跟疼痛病症相似。因此，本研究利用磁共振成像（MR）制定客观的形态学标准，以对8例患者的足底筋膜炎进行诊断。获取了有症状和无症状足部的矢状面T1加权、冠状面中等加权和T2加权图像；对有症状的足部还使用了其他序列。与年龄和性别匹配的志愿者（矢状面，3.22 mm±0.44，冠状面，3.44 mm±0.53）以及年轻男性对照组（矢状面，3.00 mm±（此处原文有误，应为0.8），冠状面，3.00 mm±0.0）相比，足底筋膜炎患者的足底筋膜最大厚度显著增加（P＜0.0001）（矢状面，7.40 mm±1.17，冠状面，7.56 mm±1.01）。此外，10例患有足底筋膜炎的足部中有9例在筋膜实质内出现信号强度中度增加的区域。磁共振成像可对与足底筋膜炎相关的形态学变化进行客观评估，还有助于排除足跟疼痛的其他原因。
