对曾注射全氟丙烷气体(C3F8)的兔眼进行了磁共振(MR)显微成像，其中有或没有手术造成视网膜脱离。凝固性玻璃体纵向松弛时间(T1)缩短，可用质子密度像和T1加权像鉴别。此外，梯度回波成像还可以检测玻璃体-视网膜牵引线。还可以看到脱离的视网膜本身。此外，质子密度成像但不是T1加权成像显示晶状体混浊表现为高强度区域。MR显微镜是一种对完整眼睛进行大体形态检查的简便方法。
Magnetic resonance (MR) micro-imaging was performed on enucleated eyes from rabbits previously injected with perfluoropropane gas (C3F8), with or without the surgical creation of retinal detachment. Condensed vitreous, which exhibited shortened longitudinal relaxation time (T1), could be differentiated with proton-density and T1-weighted imaging. Gradient-echo imaging could in addition detect vitreo-retinal tractions. The detached retina itself was also seen. Further, proton-density but not T1-weighted imaging showed lens opacities appearing as high-intensity regions. MR microscopy is a convenient method for gross morphological examination of intact eyes.
