Methods Nine patients with Alzheimer's disease and nine age-matched normal controls
were imaged using 18F-labeled deoxyglucose and 15O-labeled gases. Results Regional …

PET and SPECT using appropriate radioligands allow imaging of certain critical components
of neurotransmission such as presynaptic transporters and postsynaptic receptors in living …

An ideal hypoxia imaging agent should have high membrane permeability for easy access
to intracellular mitochondria and low redox potential to confer stability in normal tissue, but it …

In order to clarify the roles played by the primary motor cortex and the supplementary motor
area in the execution of complex sequential and simple repetitive finger movements, …

A parallel neural network has been proposed for processing various types of information
conveyed by faces including emotion. Using functional magnetic resonance imaging (fMRI), we …

The primary visual cortex (V1) in congenitally blind humans has been shown to be involved
in tactile discrimination tasks, indicating that there is a shift in function of this area of cortex, …

11 C-Acetate can act as a probe of tissue metabolism through entry into catabolic or anabolic
metabolic pathways as mediated by acetyl–coenzyme A. The uptake of 11 C-acetate in …

To obtain a better understanding of the cortical representation of bimanual coordination, we
measured regional cerebral blood flow (rCBF) with 15 O-labeled water and positron …

The present study was designed to assess glucose metabolism in hepatocellularcarcinoma (HCC)
with PET and [18Flfluoro deoxyglucose (FDG) and to compare the results withthe …

It has been proposed that motor imagery contains an element of sensory experiences (kinesthetic
sensations), which is a substitute for the sensory feedback that would normally arise …
