title: [Magnetic resonant imaging diagnosis and differential diagnosis in choroidal melanoma].
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.
  
  
  CONCLUSIONS
  Besides B-ultra-sonography and CT, MRI is also valuable in the diagnosis and differential diagnosis of choroidal melanoma.
