超声测量跖筋膜的数字化评价

目的　通过数字化分析评价超声测量跖筋膜的准确度。 方法　选取2014年5月至2016年5月内蒙古医科大学附属医院50名健康成人志愿者，男25名，女25名；年龄为18～51岁，平均(31.6±3.5)岁，身高155~181 cm，平均(172.3±7.6) cm；体重49~90 kg，平均(78.3 ±3.6) kg，分别行双足CT断层、MRI断层与超声检查，记录超声图像上的跖筋膜厚度，将CT、MRI原始图像数据以dicom格式导入Materialise Mimics Innovation Suite 16.0软件，进行数字化分析、测量，比较三者的相关性。 结果　超声、CT、MRI三者之间的测量在同性别之间差异无统计学意义（P＞0.05）。同一性别的左、右两侧差异无统计学意义（P＞0.05），而同一侧在男、女性别之间差异有统计学意义，三种检查结果跖筋膜平均厚度男性大于女性，（P＜0.05）。 结论　超声检查能够为跖筋膜厚度的测量提供相对简便的方法而且准确度较高。

Digital evaluation of the reliability of plantar fascia by ultrasonography

Objective　To evaluate the reliability of the plantar fascia by ultrasonography.　Methods 50 healthy adult volunteers (25 males and 25 females) were involved in this research. Images of the plantar fascia from 100 feet were acquired by ultrasonography, CT and MRI scanning, and recording the plantar fascia thickness of ultrasound image. Image data of CT and MRI in DICOM format were transformed into Materialise Mimics Innovation Suite 16 software for digital analysis. The reliability was compared among these three image data.　Results　There was no significant difference among the three groups in ultrasound, CT and MRI in the same gender (P>0.05). There was no statistical significance of the same sex differences between the left and right sides (P>0.05). There was significant difference of the same side between the male and female.the average thickness of the plantar fascia in males was larger than in females (P<0.05).Conclusion　Ultrasonography can provide a relatively simple and reliable method for the measurement of plantar fascia thickness.
