彩色多普勒超声和CT、MRI在眼眶疾病的诊断评价

Evaluation of ultrasonography,CT and MRI in diagnosing orbit diseases

目的:评价彩色多普勒超声(CDFI)和X线计算机体层成像(CT)、磁共振成像(MRI)在眼眶疾病的诊断价值。方法:回顾性总结84例眼眶疾病的影像诊断,评估分析CDFI和CT、MRI的诊断价值。结果:物理诊断符合率CDFI和CT、MRI无明显差异。CDFI和CT、MRI病理符合率在实质性肿块中分别为92%、89.3%,含液性包块分别为100%、90%,炎性病变分别为100%、95.7%,血管病变分别为100%、77.8%。结论:眶内液性病变定性诊断CDFI稍优于CT,病变侵犯眼眶甚至颅内或颅内病变侵犯眼眶则CT、MRI更胜一筹。

Objective：To evaluate the role of ultrasonography （US） in diagnosing orbit diseases,compared with CT and MRI. Methods：The image datum of 84 cases were retrospectively analyzed and correlated with postoperative pathology results. Results-On physical diagnosis,US and CT/MRI showed no significant difference. When correlated with pathology,the coincidences of US and CT/MRI were：solid lesion,92% and 89.3% ;cystic lesion, 100% and 90% ;inflammatory lesion, 100% and 95.7% ;vascular lesion, 100% and 77.8%. Conclusion：On intra-orbit lesions,US is superior to CT/MRI,because it is cheap,safe,sensitive and real-time. However,CT/MRI might be better,if the lesion intrudes the eye sockets.
