TIA x RIND x completed stroke
 35% of TIA’s have DWI MR lesions
 Same mortality and morbidity as minor
stroke
 AHA-ASA 2009 new definition of TIA:
= tissue definition

 No signs of acute MR or CT lesion
ischemie
hemorhagie
• Gold standard
• ischemic / hemorhagic
+ availability, speed, senzitivity for hemorhagy,...
- negative first 3-6 hours, poor for brainstem
Native CT – markers of early ischaemia:
Early hypodenzity
Lower difference between gray x white matter
Lost gyrification (SA space)
Dense artery sign (MCA)
