The purpose of the work reported here was to describe the sonoelastographic appearance of the plantar fascia of healthy volunteers and patients with fasciitis. Twenty-three healthy subjects and 21 patients with plantar fasciitis were examined using B-mode and real-time sonoelastography (RTSR) scanning. B-Mode examination included fascia thickness and echotexture. Echogenicity and echovariation of the color histogram were analyzed. Fasciae were classified into type 1, blue (more elastic); type 2, blue/green (intermediate); or type 3, green (less elastic). RTSE revealed 72.7% of fasciae as type 2, with no significant association with fasciitis (χ(2) = 3.6, df = 2, p = 0.17). Quantitative analysis of the color histogram revealed a significantly greater intensity of green (mean = 77.8, 95% confidence interval [CI] = 71.9-83.6) and blue (mean = 74.2, 95% CI = 69.7-78.8) in healthy subjects. Echovariation of the color red was 33.4% higher in the fasciitis group than in the healthy group (95% CI = 16.7-50.1). Sonoelastography with quantitative analysis of echovariation can be a useful tool for evaluation of plantar fascia pathology.
本文报告的工作目的是描述健康志愿者和足底筋膜炎患者足底筋膜的超声弹性成像表现。对23名健康受试者和21名足底筋膜炎患者进行了B超和实时超声弹性成像（RTSR）扫描检查。B超检查包括筋膜厚度和回声纹理。分析了彩色直方图的回声性和回声变化。筋膜分为1型，蓝色（弹性更强）；2型，蓝/绿色（中等）；或3型，绿色（弹性较小）。实时超声弹性成像显示72.7%的筋膜为2型，与筋膜炎无显著相关性（χ(2)=3.6，自由度=2，p=0.17）。彩色直方图的定量分析显示，健康受试者绿色（平均值=77.8，95%置信区间[CI]=71.9-83.6）和蓝色（平均值=74.2，95%CI=69.7-78.8）的强度明显更高。筋膜炎组红色的回声变化比健康组高33.4%（95%CI=16.7-50.1）。结合回声变化定量分析的超声弹性成像可作为评估足底筋膜病变的有用工具。
