彩超对甲状腺乳头状微癌的诊断价值

Value of High-frequency Color Doppler Ultrasound in Papillary Microcarcinoma of the Thyroid

目的:探讨彩色超声对甲状腺乳头状微癌的诊断价值。方法:对48例甲状腺乳头状微癌的彩色多普勒声像图特征及颈淋巴结转移的特点进行分析。结果:根据超声图像的边界、包膜、内部回声、微钙化及颈部淋巴结的特征可以对甲状腺乳头状微癌进行诊断,超声诊断符合率72.9%。按声像图特征分为两种类型:低回声型和低晕环型。两种类型在出现毛刺征和颈部淋巴结转移上比较差异有统计学意义(P<0.05),在血流程度分级、微钙化发生率上比较差异无统计学意义(P>0.05)。结论:彩超可以对甲状腺乳头状微癌的诊断及手术治疗提供有价值的参考依据。

Objective： To evaluate the use of color Doppler ultrasound in papillary microeareinoma of the thyroid. Methods： The color Doppler images of 48 cases of papillary microcarcinoma of the thyroid with cervical lymph node metastasis were analyzed. Results： Thyroid papillary carcinoma can be diagnosed according to features detected by ultrasound, including the margin, capsule, echogenicity, and microcalcification pattern in the lymph nodes, with an accuracy rate of 72.9%. According to features of the images, the sonograms were divided into 2 classes： the hypo-echo and hypo-echo halo type. There was a significant difference in the comparison between spicules and cervical lymph node metastasis （P〈0.05）, and detection of microcalcifications and the extensiveness of the blood supply were found not to be statistically significant factors （P〉0.05） in the two types. Conclusion： Ultrasonography may provide a more accurate diagnosis and may assist the clinician in the decision of whether or not to perform surgery to remove papillary microcarcinoma of the thyroid.
