B超联合CT在眼球内异物诊断定位中的应用

目的探讨球内异物超声及口影像定位的临床价值。方法患者分别进行B超和CT检查，诊断异物、定位并与手术结果进行比较。结果55眼中B超显影55例，CT显影53例，根据CT定位与术中发现异物基本符合。结论B超结合CT对诊断和定位眼球内异物是好方法。

Dignostic value of combining CT and B-type ultrasound in localization of intraocular foreign bodies

Objective To explore the diagnostic value of combining CT and B-type ultrasound in localization of intraocular foreign bodies.Methods 55 cases with 55 intraocular foreign bodies were detected and localized by CT and B-type ultrasound scan.55 cases with 55 intraocular foreign bodies were detected and localized by B-type ultrasound combined with CT.The observation were compared to the introoperative findings.Results All 55 foreign bodies wre detected by CT and B-type ultrasound scan.The accuracy of B-type ultrasound combined with CT in localization was high.Conclusion CT scan combined with B-type ultrasound is feasible and should be routinely carried out in diagnosis and localization of intraocular foreign bodies.
