高频超声在细小神经诊疗中的临床应用

目前CT、MRI等影像技术均难以对细小周围神经进行实时动态观察。随着超声技术的快速发展,超声分辨率不断提高,应用高频超声对一些细小神经进行观察成为可能,并逐渐应用于多种疾病的诊断与鉴别诊断。通过超声显像确定细小神经的解剖位置可以精准地引导神经阻滞,通过观测神经的横截面积、回声及血流信号等参数的变化,可为多种疾病的诊断及疗效评估提供参考依据。本文就高频超声对各细小神经显像和相关诊断,以及其在神经阻滞中的应用现状进行综述。

Clinical application of high frequency sonography in diagnosis and treatment of small nerves

For small peripheral nerves,traditional imaging techniques such as CT and MRI are difficult to display in real time.With the advancement of ultrasound technology and the increasing resolution of ultrasound imaging,it is possible to observe some small nerves by high-frequency ultrasound and gradually apply it in the diagnosis and differential diagnosis of various diseases.The anatomy of these small nerves by ultrasound imaging can provide accurately guidance for nerve block.In addition,the changes of parameters such as nerve cross-sectional area,echo and blood flow signals can provide a basis for diagnosis and evaluation of the efficacy of various diseases.This article reviews high-frequency ultrasound technology of various small nerves and related diagnosis and its application status in nerve block.
