MRI Brain - Axial T2 - Cerebellar infarct

  • This patient presented with a sudden onset cerebellar syndrome
  • An area of high signal (bright area) in the right cerebellar hemisphere represents oedema
  • In this clinical context the oedema indicates a posterior circulation infarct
  • (Same patient as image below)

DWI/ADC - Cerebellar infarct

  • (Same patient as image above)
  • Confirmation of a recent ischaemic event can be gained by performing Diffusion Weighted Imaging (DWI) and the Apparent Diffusion Coefficient (ADC) images which are viewed together
  • The area of high signal on the DWI image correlates with an area of low signal on the ADC image
  • This pattern indicates restricted diffusion – a sign of recent ischaemia
