眶内异物的现代诊断(附18例报告)

The modern methords in diagonising orbital foreign bodies

对１８例眶内异物的影像检查进行分析比较，认为传统的Ｘ线能初步筛选金属异物，且价格低廉；Ｂ超对眶浅部异物的定性定位有优势；ＣＴ扫描对各类异物的定性定位准确率高（９４％）。比较几种诊断方法的价值，Ｂ超、ＣＴ等现代影像技术的综合使用，明显提高眶内异物的检出率。

s 18 cases of orbital foreign bodies wereanalyzed with respect to the patients'X-ray、B-ult-rasonography and computed tomography. CT had highaccurancy in determing their location and nature,B-ultrasound was also dominance when foreign bodieswere in anterion orbit. X-ray was in low price. The auther proved the detectable rate will have obviously been promoted by B-ultrasound and CT,they are effective and necessary methords at present.
