【摘要】:目的分析不同部位甲状腺乳头状癌的灰阶超声及弹性成像特点。方法术后经病理证实为乳头状癌的甲状腺结节64个,按照病变所在部位将结节分成上极、中部、下极三组,观测不同部位结节的灰阶超声、彩色血流以及弹性成像特点。结果甲状腺乳头状癌结节灰阶图像多表现为低回声结节,边界不清,形态不规则,纵横比1;血流分布特点以Ⅱ、Ⅲ级为主;弹性成像评分以Ⅲ、Ⅳ分为主。两两比较,上极、中部、下极三组结节血流阻力指数(RI)差异没有显著统计学意义(P0.05);上极结节与中部结节、中部结节与下极结节弹性应变率比值(SR)无差异(P0.05),上极结节与下极结节SR有差异(P值0.02)。结论不同部位甲状腺乳头状癌彩色血流显像无明显差异,上极乳头状癌结节硬度高于下极。
[Abstract]:Objective to analyze the features of gray-scale ultrasonography and elastic imaging of papillary thyroid carcinoma. Methods Sixty-four thyroid nodules proved to be papillary carcinoma were divided into three groups according to the location of the lesions. The gray scale ultrasound, color blood flow and elastic imaging of the nodules were observed. Results the gray-scale images of papillary thyroid carcinoma showed hypoechoic nodules with unclear boundary irregular shape and aspect ratio of 1. The distribution of blood flow was mainly of grade 鈪,
