      【摘要】 腕管疾病常见且病因错杂，腕管解剖结构复杂以致任何其内部结构体积增加的情况均可能导致腕管
压力增加，同时可能引起正中神经受压出现相关症状。本文复习了腕管的解剖以及分析影响该区域的疾病，探讨
平片、MRI、超声、以及CT在腕管影像诊断中的应用，并概述以上方法的优缺点。研究表明，MRI、超声、CT在腕管
疾病的诊断中各具优势，此外，双能量CT因继承了单能量CT的优势并具有较好观测软组织的潜能，使其在腕管的
应用中具有一定的前景，联合使用多种影像方法能够为临床提供更为丰富、准确的诊断信息。

【Abstract】 Carpal tunnel syndrome is common and its causes are intricate. Due to the complicated structure of
carpal tunnel, the increase of the volume of internal structure can lead to the increase of carpal tunnel pressure, and it can
also cause some symptoms related to the carpal tunnel as the median nerve compression. In this article, we review the
anatomy of the carpal tunnel, the diseases affecting this region, and then discuss the use of conventional radiographs,
magnetic resonance imaging (MRI), ultrasound and CT, and outline the strengths and weaknesses of each method in car-
pal tunnel. MRI, ultrasound and CT all have their own advantages in the diagnosis of carpal tunnel diseases correspond-
ingly. The combination of multiple imaging methods can provide more abundant and accurate diagnostic information for
clinical application. In addition, dual energy computed tomography (DECT) inherits the advantages of single energy
computed tomography (SECT) and has potential to better observe the soft tissue, making it having a good prospect in the
application of carpal tunnel.
