Background: Patterns of altered cerebral perfusion and cognitive dysfunction have been described in Bipolar Disorder (BD) acute episodes and euthymia. Knowledge of the relationship between cognitive function and perfusion in a manic state and status when followed up is still limited.
Objective: To describe brain perfusion alterations and its relationship with cognitive impairment in patients with BD during manic episodes and after 6 months.
Background: We aimed to describe orbital positron emission tomography/computed tomography (PET/CT) imaging findings, both structural and metabolic, in different clinical stages of Graves ophthalmopathy (GO). This prospective, observational, cross-sectional study examined 32 eyes of 16 patients with GO.
Methods: Patients were assessed with a complete ophthalmological evaluation and assigned a VISA classification for GO.
Objective. To compare 18-fluorodeoxyglucose (FDG) uptake by positron emission tomography (PET) in extraocular muscles (EOMs) of patients with Graves' ophthalmopathy (GO) versus patients without GO. Design.

Material And Methods: Three Wistar adult male rats were studied in three different protocols: no fasting group, fasting group over a period of 12 hr before the study with only water provided ad libitum, and fasting group by the same time receiving an oral 50% glucose solution. Thirty-minute acquisition images were obtained with a micro-PET, thirty and sixty minutes after the administration of 370-555 MBq 18F-FDG.
Objective: To evaluate the role of PET and MRI fused image study inpatients with primary brain tumors previously treated, to determine the presence of radionecrosis vs residual tumor viability.
Methods: Primary brain tumors were diagnosed by biopse and MR. 18FDG-PET scan and T1 enhanced MRI follow-up studies were performed between 3 and 5 months after treatment.
