将硅胶带、硅胶海绵、人工晶状体、甲基纤维素和硅油置入４只兔的８眼内和眼球周围，探讨其ＣＴ和ＭＲＩ表现。植入物置入后２ｈ内完成ＣＴ和ＭＲＩ。ＭＲＩ选用ＳＥ序列Ｔ１ＷＩ、ＰＤＷＩ、Ｔ２ＷＩ和Ｆｌａｓｈ２ｄ序列。结果：３枚硅胶带和２枚人工晶状体ＣＴ未显示，ＭＲＩ呈低信号全部显示；３枚硅胶海绵ＣＴ显示低密度，ＭＲＩ呈低信号，均被检出；玻璃体内硅油ＣＴ呈高密度，Ｔ１ＷＩ和ＰＤＷＩ呈高信号，Ｔ２ＷＩ和Ｆｌａｓｈ２ｄ序列呈低信号而被检出；眼房和玻璃体内甲基纤维素ＣＴ和ＭＲＩ均未显示。结果提示：ＣＴ和ＭＲＩ均是检出玻璃体内硅油和眶内硅胶海绵的有效方法，检出眶内硅胶带和眼内人工晶状体以ＭＲＩ为优；ＣＴ和ＭＲＩ难以发现眼内甲基纤维素
Silicone tape, silicone sponge, intraocular lens, methylcellulose and silicone oil were placed in 8 rabbits and 4 eyes around the eye, to explore the CT and MRI findings. CT and MRI were completed within 2 h after implant placement. Selective T1 sequence MRI T1WI, PDWI, T2WI and Flash2d sequence. Results: Three silicone strips and two intraocular lenses were not shown. All the MRI showed low signal intensity. Three silicone sponge CT images showed low density and MRI showed low signal, all of them were detected. Vitreous silicone oil CT showed high density, T1WI And PDWI showed high signal, T2WI and Flash2d sequences were detected as low signal; intraocular and intravitreal methyl cellulose CT and MRI were not shown. The results suggest that both CT and MRI are effective methods to detect intraosseous silicone oil and intraorbital silicone sponge. The detection of intraorbital silicone tape and intraocular lens is superior to MRI. CT and MRI are difficult to find intraocular methylcellulose
