摘要
目的：探讨磁共振成像（ｍａｇｎｅｔｉｃｒｅｓｏｎａｎｃｅｉｍａｇｉｎｇ，ＭＲＩ）在眼内肿瘤诊断中的价值及成像方法。方法：４６例眼内肿瘤，包括脉络膜黑色素瘤２０例，视网膜母细胞瘤１８例，Ｃｏａｔｓ病６例和脉络膜血管瘤２例，进行ＭＲＩ检查，并将检查结果与各自的Ｂ型超声波和其中３２例的ＣＴ检查资料对比分析。结果：在眼内肿瘤的发现方面，Ｂ型超声波、ＣＴ、ＭＲＩ三者间无显著差异（Ｐ＞０．３，χ２＝１．０７１６）。在定位和定性方面三者有非常显著的差异（Ｐ＜０．０１，定位χ２＝３．６５９，定性χ２＝２９．８３１４）。结论：眼内肿瘤的定位定性和肿瘤继发损害的检查中，ＭＲＩ较优于ＣＴ和超声检查。
OBJECTIVE:To investigate the diagnostic meaning of MRI in intraocular tumors.METHODS:Forty six cases of confirmed intraocular tumors,including choroidal melanoma(20 cases),retinoblastoma(18 cases), Coats disease(6 cases)and choroidal hemangioma(2 cases), were studied with MRI and compared with ultrasonography and CT. RESULTS:In making discoveries about intraocular tumors,there were no significant difference between MRI and B ultrasonography or CT (P>0.3,χ 2=1.0716)while there were highly statistic significance in deciding characters and position (P<0.01,deciding character χ 2=29.8314,position χ 2=13.659)of them. CONCLUSION:Among the examinations to find out about the position,character and secondary pathological insults of intraocular tumors MRI might be more available than CT and ultrasonography.
