Effect of Piracetam on Cerebral Glucose Metabolism in Alzheimer's Disease as Measured by Positron Emission Tomography

Cerebral glucose metabolism on positron emission tomography of children.

Establishing the normative range of age-dependent fluorodeoxyglucose (FDG) uptake in the developing brain is necessary for understanding regional quantitative analysis of positron emission tomography (PET) brain images in children and also to provide functional information on brain development. We analyzed head sections of FDG PET/computed tomography (CT) images for 115 patients (5 months to 23...

The effect of fasting on Positron Emission Tomography (PET) imaging

As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...

Positron emission tomography studies of abnormal glucose metabolism in schizophrenia.

Schizophrenia, a devastating disease characterized by a combination of various types of disturbed behaviors, thoughts, and feelings, may likewise be heterogeneous in etiology. Recent advances in neuroscience and psychopharmacology have suggested a wide array of competing mechanisms that may be involved in schizophrenia, including but not limited to deficits in one or more neurotransmitters and ...

The cerebral metabolism of glucose and oxygen measured with positron tomography in patients with mitochondrial diseases.

Cerebral oxygen and glucose metabolism have been studied in 8 patients with biochemically defined mitochondrial myopathies and 7 normal control subjects using positron emission tomography. Four patients had myopathy alone and 4 had predominantly central nervous system (CNS) disease. Cerebral oxygen and glucose metabolism were measured concurrently in the two groups of patients with 15O, 11C and...
