摘　　要：直肠癌是常见的消化道恶性肿瘤,直肠腔内超声已成为诊断直肠癌的首选方法,尤其在评价直肠癌术前分期中的作用优势显著,近年来直肠腔内超声发展迅速,除了常规的腔内超声,还发展了各种改良法腔内超声显影,克服了诸多常规腔内超声的弊端,提高了术前分期的准确率,随着进一步研究,发现腔内超声造影、三维重建技术、弹性成像技术及腔内超声活检等新技术同样都适用于直肠癌的诊断,并有助于提高直肠癌术前分期的准确率,下面对直肠腔内超声各种检查方法进行综述。Colorectal cancer is a common malignant tumor of alimentary canal. Transrectal ultrasound has become the preferred method for diagnosis of rectal carcinoma. Especially colorectal cancer role in preoperative staging advantage is very signiflcant,ln addition to conventional endoluminal sonography,also developed a variety of modifled method of intraluminal ultrasound imaging and overcomes many conventional,Transrectal ultrasound drawbacks and improve the accuracy of preoperative staging.With further study. Found that many of the same techniques areapplicable to colorectal cancer diagnosis such as intracardiac ultrasound imaging,3 Dreconstruction techniques,elasticity imaging technology and intraluminal ultrasound biopsy and other new technologies,it heips improve the accuracy of presurgical staging of colorectal cancer,overview of various techniques below transrectal ultrasound.
