摘　　要：目的 探讨彩色多普勒超声、MRI动态增强对眼内或眶内占位病变诊断及监测价值。方法 回顾性分析本院2018年9月至2019年9月期间收治的106例眼内或眶内占位病变患者的临床资料,比较不同检查方法 对眼内或眶内占位病变诊断的准确性、敏感性以及特异性,总结病灶影像学征象。结果 MRI检查对眼内或眶内占位病变诊断的准确性、敏感性以及特异性较高于超声诊断,两者联合检查的诊断明显高于单一的超声检查或MRI检查的诊断(P<0.05);超声表现:视网膜母细胞瘤多呈团块状,边界欠清,回声不均匀血流信号丰富;脉络膜黑色素瘤多呈半球状,且有明显挖空症状,血流信号清晰可见;眼眶炎性假瘤形态欠规则,内部低回声;MRI表现:视网膜母细胞瘤在TWI呈低信号;脉络膜黑色素瘤在TWI呈高信号,且均在增强后有所强化;眼眶炎性假瘤在T与TW1中呈低信号,增强后强化不明显。结论 超声与MRI检查均可有效诊断眼内或眶内占位病变,但两者联合检查可综合其影像学表现,对眼内或眶内占位病变的诊断价值也更高。Objective To explore the value of color Doppler ultrasound and MRI dynamic enhancement in the diagnosis and monitoring of intraocular or intraorbital space-occupying lesions.Methods The clinical data of 106 patients with intraocula r or intra orbital space-occupying lesions admitted to our hospital from September 2018 to September 2019 were retrospectively analyzed.The accuracy,sensitivity and specificity of different examinations in the diagnosis of intraocular or intraorbital space-occupying lesions were compared,and the imaging signs of the lesions were summarized.Results The accuracy,sensitivity and specificity of MRI examination in the diagnosis of intraocular or intraorbital spaceoccupying lesions is higher than that of ultrasound.The accuracy,sensitivity and specificity of the combined examination of them were significantly higher than that of single ultrasound examination or MRI examination(P<0.05).Ultrasound showed that the retinoblastoma showed mostly mass-like,the border was not clear,the echo was uneven,and the blood flow signal was rich.Choroidal melanoma was mostly hemispherical,with obvious hollowing symptoms,and the blood flow signal was clearly visible.The orbital inflammatory pseudotumor had an irregular shape and low internal echo.MRI showed that retinoblastoma showed a low signal on TWI;choroidal melanoma showed a high signal on TWI,and both they were enhanced after enhancement.The orbital inflammatory pseudotumor showed a low signal in TWI and TW1,and the enhancement was not obvious after enhancement.Conclusion Ultrasound and MRI examinations can effectively diagnose intraocular or intraorbital spaceoccupying lesions,but the joint exa mination of them can synthesize their imaging manifestations and have higher diagnostic value for intraocular or intraorbital space-occupying lesions.
