Abstract
OBJECTIVE
To evaluate the diagnostic value of magnetic resonant imaging (MRI) for choroidal melanoma.
METHODS
12 cases of choroidal melanoma were diagnosed by means of B-ultra-sonography, computed tomography (CT), MRI and pathology.
RESULTS
The MRI features of melanoma were: T(1)WI shows high signal, and T(2)WI shows low signal.
CONCLUSION
Besides B-ultra-sonography and CT, MRI is also valuable in the diagnosis and differential diagnosis of choroidal melanoma.
摘要
目的
评估磁共振成像（MRI）对脉络膜黑色素瘤的诊断价值。
方法
采用B超、计算机断层扫描（CT）、MRI及病理检查对12例脉络膜黑色素瘤进行诊断。
结果
黑色素瘤的MRI表现为：T(1)WI呈高信号，T(2)WI呈低信号。
结论
除B超和CT外，MRI对脉络膜黑色素瘤的诊断及鉴别诊断也具有重要价值。
