摘　　要：目的分析正常跗管结构高频超声声像图特点。方法对40例健康志愿者(男20例,女20例)行高频超声(12 MHz)检查,从短轴切面与长轴切面动态观察跗管内肌腱、神经与血管声像图表现,测量跗管与胫神经短轴切面面积,并比较男女间差异。结果高频超声声像图能清晰显示跗管解剖结构。肌腱、神经和血管在声像图中表现为不同特点,易于鉴别。跗管短轴切面面积:男性(7.61±1.00)cm2,女性(6.61±1.07)cm2(P<0.01)。跗管内胫神经短轴切面面积:男性(9.59±0.75)mm2,女性(8.91±0.74)mm2(P<0.01)。结论高频超声声像图能清晰显示并准确测量跗管结构,准确掌握跗管结构正常声像图解剖特点,有助于提高跗管病变的超声诊断效率。Objective To analyze the features of normal high-frequency ultrasonography of tarsal tunnel. Methods Forty volunteers （20 males and 20 females） were examined with high-frequency ultrasound （12 MHz）. The tendons,nerve and blood vessels in tarsal tunnel were observed from short-axis and long-axis views dynamically. The areas of tarsal tunnel and posterior tibial nerve were measured and com-pared between the males and females. Results High-frequency ultrasonography depicted the anatomical structure of tarsal tunnel,and the tendons,nerve and blood vessels presented different sonographic features that were easy to differentiate. The area of tarsal tunnel： male （7.61 ±1.00） cm2,female （6. 61 ± 1. 07） cm2 （P 〈0. 01）. The area of posterior tibial nerve： male （9. 59 ± 0. 75） mm2,female （8.91 ±0.74） mm2（P〈0.01）. Conclusion High-frequency ultrasonography can clearly show and accurately measure the tarsal tunnel structure. To be familiar with the normal ultrasonographic anatomy of tarsal tunnel will help to improve the efficacy of ultrasound diagnosis of tarsal tunnel abnormalities.
