title: Serial dynamic magnetic resonance imaging of orbital cavernous hemangioma.
abstract: OBJECTIVE
  To assess serial dynamic magnetic resonance imaging after rapid intravenous injection of contrast material as a tool for diagnosing orbital cavernous hemangioma.
  
  
  METHODS
  Two patients with orbital cavernous hemangioma were studied. Gadolinium-DTPA, 0.1 mmol/kg, was injected intravenously in 10 seconds.
  
  
  RESULTS
  On early imaging after the injection, one small point of enhancement was initially noted, and then the tumor was homogeneously enhanced. The initial enhancement point represented the connecting point of feeding vessels to the lesion.
  
  
  CONCLUSIONS
  Dynamic magnetic resonance imaging is useful for diagnosing cavernous hemangioma and for estimating the connecting point of feeding vessels.
