摘　　要：目的探讨低场强MRI对甲状腺的诊断和鉴别诊断。方法回顾分析经穿刺活检或手术病理证实的36例甲状腺肿块,均采用了西门子0.35低场强MRI仪器检查。结果36例甲状腺肿块中,甲状腺癌9例,甲状腺腺瘤19例,结节性甲状腺肿5例,甲状腺囊肿3例。低场强MRI对恶性病变的诊断率67%,对良性病变诊断的符合率67%。结论掌握各种甲状腺病变的低场强MRI信号特点、与周围结构的关系,以及有无颈部淋巴结转移,对其诊断及鉴别诊断具有重要价值。Objective To study the low-field MRI of thyroid diagnosis and differential diagnosis. Methods A retrospective analysis by biopsy or surgical pathology of goiter block 36, using the Siemens 0.35 low field MRI examination equipment. Results 36 cases of thyroid, 9 cases of thyroid cancer, thyroid adenoma in 19 cases, 5cases of nodular goiter, 3 cases of thyroid cysts. Low-field MRI for the diagnosis rate of malignant lesions 67% of benign lesions diagnosed with the rate of 67%. Conclusion Thyroid diseases have a variety of low-field MRI signal characteristics of the surrounding structures, as well as the availability of cervical lymph node metastases, its diagnosis and differential diagnosis of great value.
