摘　　要：目的探讨甲状旁腺腺瘤的MRI表现,结合文献评估MR对甲状旁腺腺瘤的定性、定位诊断价值。方法对临床及手术病理证实的5例甲状旁腺腺瘤患者术前均行MR检查,男3例,女2例,年龄21～39岁。所用设备为SIEMENS sonata1.5T超导型磁共振成像系统。结果5例腺瘤均位于甲状腺下极食管—气管隐窝区,4例表现为T1WI稍低信号,T2WI高信号,1例信号不均匀,病理检查示部分坏死。腺瘤边缘清晰,大小1.2cm×1.0cm×1.6cm～2.2cm×3.1cm×4.1cm。结论MRI是诊断甲状旁腺腺瘤的有效影像方法,可以准确显示腺瘤的大小、形态、部位及与周围组织结构的毗邻关系。对甲状旁腺腺瘤的诊断和临床治疗方式的选择具有重要意义。Objective To investigate the MRI findings of parathyroid adenoma and to evaluate their significance in the qualitative and localized diagnosis together with review of the literature. Methods Five patients（3 men, 2 women; aged 21 - 39 years） with surgically and pathologically proved parathroid adenoma underwent MR imaging of the parathyroid glands before the operation. All procedures were performed by using a SIEMENS sonata 1.5 T superconductive MR system. Results All lesions of parathyried adenoma in 5 patients were located in the esophagotracheal resses of：thyroid inferiority. The lesions in 4 cases were slightly hypointense signals on T1WI and hyperintense signals on T2WI. In the remaining one case, the lesion was heterogeneous intensity associated with partial necrosis which was cofirmed by pathology. On MR images, the border of lesions was clear and their size ranged from 1.2× 1.0 × 1.6（cm）to 2.2 × 3. 1 × 4. 1 （cm）. Conclusion MR imaging can accurately reveal the size, shape, location of parathyroid adenoma and its relationship with neighbor tissue structures, thus it is effective means for diagnosing parathyroid adenoma and planning its treatment protocol.
