Positron emission tomography in Rasmussen's encephalitis.

This report presents unusual positron emission tomography findings in an 11-year-old male with Rasmussen's encephalitis. This patient underwent fluorine-18 fluorodeoxyglucose positron emission tomography to localize his ictal focus before surgical consideration. Positron emission tomography disclosed marked hypermetabolism in the left cerebral hemisphere and basal ganglia with subnormal right cerebral activity and crossed cerebellar diaschisis.

Low-dose P32 therapy in essential thrombocythemia.

We present a case of an 85-year-old woman with medically refractory essential thrombocythemia and subsequent venous thrombosis. She received conservative phosphorus-32 sodium phosphate therapy for 3 mCi, approximately half the usual dose. One month later, she received a second intravenous phosphorus-32 treatment of 3.

Diffusion tensor imaging as potential biomarker of white matter injury in diffuse axonal injury.

Background And Purpose: Multiple biomarkers are used to quantify the severity of traumatic brain injury (TBI) and to predict outcome. Few are satisfactory. CT and conventional MR imaging underestimate injury and correlate poorly with outcome.
