摘　　要：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。Purpose: To evaluate the role of MRI in diagnosing thyroid tumors. Materials and methods; Twenty-eight patients underwent MRI examination and Scintigraphy, twenty-five pationts were performed with US. All patients proved thyroid tumors by surgery and pathology were retrospectively studied. Results; The characteristic MRI findings of malignant lesions were irregular shape, unclear edges, with lymphadenopathy (nine of thirteen cases). Benign tumors showed smooth margin without lymphadenopathy. Conclusion; MRI was superior to Ultrasonography and Scintigraphy in characterizing of thyroid tumors, but similar to CT. MRI was more excellent in detecting enlarged lymph node and demonstrating the relationship between thyroid tumors and surrounding structures.
