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。
Objective To evaluate the accuracy of ultrasonic measurement of plantar fascia by digital analysis. Methods Fifty healthy adult volunteers from May 2014 to May 2016 in the Affiliated Hospital of Inner Mongolia Medical University were selected, 25 males and 25 females. Their ages ranged from 18 to 51 years (mean, 31.6 ± 3.5), and ranged from 155 to 181 (172.3 ± 7.6) cm and body weight of 49-90 kg (mean, 78.3 ± 3.6) kg respectively. The bipedal CT scan, MRI and ultrasonography were performed respectively. The thickness of plantar fascia was recorded on the ultrasound images. The CT, MRI raw image data is imported into Materialize Mimics Innovation Suite 16.0 software in dicom format for digitized analysis, measurement, and comparison of the three. Results Ultrasound, CT, MRI measurement between the three was no significant difference between the same sex (P> 0.05). There was no significant difference in the left and right sides of the same sex (P> 0.05), while the same side had significant difference between men and women. The mean thickness of the plantar fascia in the three examinations was higher than that in the female <0.05). Conclusion Ultrasonography can provide a relatively simple method for the measurement of plantar fascia thickness with high accuracy.
