• No restricted diffusion.  • No focal masses, focal atrophy, or foci of restricted water diffusion.  • No evidence for acute ischemia on the diffusion weighted images.	• There is no acute territorial infarct. • No acute territorial infarct. • There is no decreased diffusion to indicate an acute infarct.
Mayo – WMD	TMC – WMD
• Mild leukoaraiosis  • Minimal leukoaraiosis  • Moderate leukoaraiosis	• There are scattered foci of hypodensity in the subcortical and periventricular white matter, a non-specific finding but likely reflecting the sequela of chronic microangiopathy • Areas of white matter hypodensity are a non-specific finding but may represent the sequela of chronic microangiopathy • There are multiple foci of t2 flair hyperintensity in the periventricular, deep and subcortical white matter, a non-specific finding but likely reflecting the sequela of chronic microangiopathy
