摘要
评价MRI对甲状腺相关眼病(TAO)临床严重度分级和活动性分期评价的影响。结果显示NOSPECS 2级和3级病例MRI均发现了眼外肌受累的证据。MRI对眼外肌受累显示的阳性率明显高于NOSPECS评分(Х^2=19.37,P=0.000)。MRI比临床活动性评分(CAS)判断“活动期”有更高敏感度、特异度、准确度(100%对95.7%、88.2%对35.3%、96.9%对79.7%)。提示MRI增加了早期不典型4级TAO的发现率,压脂T2WI信号可作为TAO活动分期的判断指标。
The influence of MRI on severity grading and activity staging in thyroid associated ophthalmopathy (TAO) was evaluated. The results showed that MRI had a higher detection rate in abnormal extraocular muscle than NOSPECS scores(Х^2 = 19.37,P = 0. 000). MRI had higher sensitivity, specificity, and accuracy in detection of active TAO than clinical activity score ( 100% vs 95.7% , 88.2% vs 35.3% , 96.9% vs 79.7%, respectively). Therefore, MRI improves early detection of atypical grade 4 cases. Signal intensity elevation in adipose suppressed T2WI is helpful to define active stage.
