| 摘 要： | 目的：分析甲状腺癌的磁共振成像（MRI）表现，提高甲状腺癌的诊断水平。方法：27例经手术和病理证实的甲状腺癌患者（乳头状癌23例，滤泡状癌2例，未分化癌和转移癌各1例）行MRI检查，男性7例，女性20例，年龄26-68岁，平均年龄48岁。观察癌结节的大小、数量、形态、边缘、信号类型、强化方式。结果：27例甲状腺癌共33个癌结节，其中单发结节23例（85％），多发结节4例（15％）。形态不规则30个，类圆形3个。T1wI呈等或略低信号32个，不规则等和高信号1个；T2wI呈均匀或不均匀高信号31个，等信号2个；结节边缘见不完整低信号环9个。增强后结节均有不同程度强化；边缘明显环形强化、中央强化稍低8个，其中“残圈征”6个，表现为结节周边强化环连续性中断、不完整；均匀强化6个；不均匀强化19个，其中乳头样强化3个，半岛样强化3个。颈部淋巴结转移7例，其中5例信号和强化不均匀。结论：甲状腺癌具有一定的形态学特征，了解其MRI表现有助于明确诊断。

| Abstract: | Objective:To study the magnetic resonance imaging(MRI) features of thyroid carcinoma to improve its diagnosis.Methods: The MRI was performed in 27 patients with surgically and pathologically proven thyroid carcinoma,including 23 with papillary carcinomas,two with follicular carcinoma,one with undifferentiated carcinoma and one with metastasis.The subjects were 20 women and 7 men with age range of 26-68 years(mean,48 years).The number,size,shape,margin,signal characteristics,and enhancement patterns of cance... |
