摘要
目的探讨MR I诊断鼻副窦炎的价值。方法回顾性分析127例鼻副窦炎的SE序列T1W I和T2W I的MR I表现。结果病变累及上颌窦78例;筛窦106例;蝶窦17例,额窦37例。筛窦炎可同时伴发上颌窦炎,所有病变均好发于右侧。所有病例均可见窦腔粘膜增厚,呈长或等T1长T2异常信号,增强后增厚粘膜有强化。结论MR I是诊断鼻副窦炎的理想检查方法。
Objective To discuss the value of MRI in diagnosing paranasal sinuses. Material and Methods MRI findings of T1 WI and T2WI of 127 cases with paranasal sinuses were analyzed retrospectly. Results There are 78 cases of maxillary sinusitis, 106 cases were ethmoid sinusitis and frontal sinuses 37cases , and 17 cases were spenoid sinusitis onlyo Ethmoid sinusitis may be concomitented maxillary sinusitis ,cases of right side were more than those of left side. The findings of MRI are mucous menbrane incrassationin in all cases, long or grade TI signal intension and long T2 signal intension, there is enhancement of incrassated mucous menbrane after injection Ga - DTPA by vein. Conclusion MRI is a perfect method in diagnosing paranasal sinusitis.
