Brain Tumours

PHYSIOLOGICAL IMAGING 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
