目的:评价MRI对甲状腺肿瘤诊断的价值。材料和方法:回顾分析经手术病理证实的28例甲状腺肿瘤,均采用飞利蒲T5MRI成像仪检查,术前28例均做过同位素检查,25例做过超声检查。结果:28例甲状腺肿瘤中,甲状腺癌13例,腺瘤15例。MRI表现恶性肿瘤多形态不规则、边缘模糊不整,淋巴结转移较常见(9/13),良性肿瘤边缘光滑,无淋巴结转移。结论:MRI在甲状腺肿瘤的定性方面优于B超和同位素,与CT相比无质的飞跃。但在观察淋巴结肿大和肿瘤与周围组织关系方面有优势。
Objective: To evaluate the value of MRI in the diagnosis of thyroid tumors. Materials and Methods: Twenty-eight cases of thyroid tumors confirmed by pathology were analyzed retrospectively using the Philips T5 MRI imager. Before surgery, 28 cases were examined for isotopes and 25 cases were examined by ultrasound. Results: Of the 28 thyroid tumors, 13 were thyroid cancer and 15 were adenomas. The MRI showed malignant tumors with irregular morphology, blurred edges, lymph node metastasis (9/13), benign tumors with smooth edges, and no lymph node metastasis. Conclusions: MRI is superior to B-ultrasound and isotopes in qualitative aspects of thyroid tumors, and has no qualitative leap compared with CT. However, there are advantages in the observation of lymphadenopathy and the relationship between the tumor and the surrounding tissue.
