超声造影多应用于腹腔实质性脏器的肿瘤良恶性诊断与鉴别诊断,而且国内外均有较成熟的研究,有研究显示超声造影在鉴别浅表淋巴结良恶性上有一定的优势,但尚未应用于直肠癌周边区域淋巴结良恶性鉴别上。我们对本院2009—2011年收治的46例直肠癌患者行术前腔内超声造影检查,进行术前分期,并与术后病理对照,控讨超声造影在直肠癌术前分期中的价值。1资料与方法1.1临床资料46例直肠癌患者,其中男25例,女21例,年
Ultrasound has many applications in the diagnosis and differential diagnosis of benign and malignant tumors in abdominal abdominal organs, and has more mature research at home and abroad. Some studies have shown that CEUS has certain advantages in differentiating superficial lymph nodes from benign and malignant diseases, but has not been applied yet In the surrounding area of rectal cancer benign and malignant lymph nodes. 46 patients with rectal cancer treated in our hospital from 2009 to 2011 were examined with preoperative intraoperative contrast echocardiography, and preoperative staging was performed. The results were compared with postoperative pathology to evaluate the value of contrast echocardiography in the preoperative staging of rectal cancer. 1 Materials and Methods 1.1 Clinical data 46 cases of rectal cancer patients, including 25 males and 21 females,
