Bayesian image reconstruction for emission tomography based on median root prior
The aim of the present study was to investigate a new type of Bayesian one-step late reconstruction method which utilizes a median root prior (MRP). The method favours images which have locallyExpand

Glucose-free fatty acid cycle operates in human heart and skeletal muscle in vivo.
Positron emission tomography permits noninvasive measurement of regional glucose uptake in vivo in humans. We employed this technique to determine the effect of FFA on glucose uptake in leg, arm, andExpand
