摘要
目的探讨甲状旁腺腺瘤的MRI表现特点。方法40例经手术病理证实的病例进行MRI平扫及增强扫描。结果肿瘤常见于颈下部气管食管隐窝区,颈动脉鞘内侧,也可位于上纵隔;呈卵圆型,有完整的包膜。可出现坏死、液化及囊性变;MRI表现T1WI呈等、等高及等低信号,T2WI上呈高信号,坏死、囊变区信号明显增高,增强扫描后肿瘤明显强化。结论MRI具有较高的软组织分辨能力及三维、多参数成像功能,对甲状旁腺腺瘤的诊断更具优越性、敏感性和准确性。
Objective To study MRI imaging features of parathyroid adenoma. Methods 4 cases of parathyroid adenoma proved by operation and pathology were scan and enhancement scan. Results Tumor were usually at esophagotracheal recess, arteria carotis side or upper mediastinum. The adenomas were oval and had whole capsule. The tumor could appear necrosis, liquefaction and cystic; Magnetic resonance showed intermediate, intermediate high and low signal on T1WI and high signal on T2WI, high signal markedly on necrosis and cystic places. Parathyroid adenoma was enhanced markedly after enhancement scan. Con- clusion Magnetic resonance had higher differentiate ability of soft tissue and three - dimensional, multi - parameter functions and had superiorirty, sensitivity and accuracity on parathyroid adenom diagnosisa.
