目的：探讨视网膜脱离的MRI表现及诊断价值。方法回顾性分析21例(22只眼)视网膜脱离患者的MRI图像特征。结果部分性脱离19只眼，完全性脱离3只；病变信号强度T1WI表现为等略高信号(18/22)为主，3只眼表现为较低信号， T2WI信号均呈高信号，其中1只眼可见分层；合并脉络膜脱离2例，合并晶状体脱位1例，脉络膜黑色素瘤伴继发性视网膜脱离1例，视网膜脱离伴出血1例。结论视网膜脱离的MRI表现较具特征性，伴有出血时可见分层现象，MRI对视网膜脱离的诊断具有重要价值。

Objective To assess the MRI manifestations and diagnostic value in retinal detachment. Methods To retrospectively analyze MRI findings of 21cases(22 eyes) with retinal detachment. Results 19 eyes were found part detachment and 3 complete detachment. On T1WI,lesions mostly presented moderate or slightly high signal intensity(18/22), only 3 slightly hypointensity;Lesion signal intensity was all hyperintensity on T2WI. Only 1 was found layering;2 complicated with choroidal detachment;1 with lens dislocation, 1 melanoma of choroids with the secondary retinal detachment and 1 with hemorrhage. Conclusions The MRI manifestations of retinal detachment reveal some features, the layering effect was found retinal detachment with hemorrhage, they have a high value in clinical diagnosis.
