经直肠弹性成像结合灰阶超声对直肠癌诊断及分期的应用进展

Progress in the application of transrectal elastic imaging combined with gray scale ultrasound in the diagnosis and staging of rectal tumors

摘要:

直肠癌是消化道常见的恶性肿瘤，弹性成像（UE）作为超声检查的新技术，可根据直肠肿瘤及周围正常组织的硬度间接判断肿瘤的良、恶性及分期，辅助传统灰阶超声提高诊断直肠癌的准确率。该文综述经直肠UE技术结合灰阶超声在诊断直肠癌中的应用进展。

Abstract:

Rectal cancer is one of the common malignant diseases of the digestive tract. Elastic imaging (UE), as a new ultrasound technology, can indirectly determine the benign, malignant and staging of the tumor according to the hardness of the rectal tumor and the surrounding normal tissue, and improve the accuracy of the diagnosis of rectal tumor by assisting the traditional gray ultrasound. This article reviews the application of trans-rectal UE technique combined with gray scale ultrasound in the diagnosis of rectal tumors.
