DWI MRI
•
Differential diagnosis of cerebral abscess,
epidermoid cyst, traumatic shearing injury,
toxic and infectious encephalitis, immediate
post brain injury
•
Postoperative ischemia
•
Accurate interpretation of new abnormal
contrast enhancement developing soon after
tumor resection
PITFALL
: Para or ferromagnetic materials such
as blood products or calcium within the brain
can simulate pathology on DWI as well as
perfusion MRI
Brain abscess
Epidermoid
