title: [Brain abscesses in diffusion-weighted imaging (DWI)--comparison to cystic brain tumors].
abstract: OBJECTIVE
  The clinical usefulness of diffusion-weighted imaging (DWI) was evaluated in patients with brain abscesses in comparison to patients with cystic brain tumors.
  
  
  METHODS
  Five patients with surgically confirmed brain abscesses underwent beside a brain MRI examination with contrast media application diffusion weighted imaging. Apparent diffusion coefficients (rADC) in three orthogonal diffusion gradient were calculated. The same protocol was used to examine 5 patients with cystic brain tumors.
  
  
  RESULTS
  Showing an rADC of 0.33 x 10(-3)/mm(2)/s abscesses have a highly restricted diffusion in comparison to cystic brain tumors with an rADC of 1,67 x 10(-3)/mm(2)/s.
  
  
  CONCLUSIONS
  Diffusion weighted imaging is a usefull diagnostic tool in the work up of brain abscesses.
