Page 2095
Zanzonico and colleagues investigate the effects of continuing antithyroid drugs at a reduced dosage during 131I therapy to reduce extrathyroid radiation without significantly reducing the target tissue dose.
Page 2102
Shin and colleagues develop a dual-imaging reporter gene system and examine the correlation between cancer cell number and signals from 2 reporter genes, a method that could be used to evaluate the effects of various therapeutic approaches.
Page 2109
Bergmann and colleagues elucidate the tumor cell transport mechanism for a novel 18F-labeled phenylalanine derivative that is presented as a potential PET tracer for imaging of amino acid transport intumors.

| ON THE COVER
This whole-body PET image of a healthy male volunteer shows that most of the radioactivity is distributed in the urinary bladder, indicating prompt excretion through the renal system. Renal pelvis, stomach, salivary glands, liver, kidneys, spleen, and vertebral column were also clearly visualized. However, uptake in myocardium, pancreas, and lungs was low. The distribution of 11C-MP4B in the brains of patients with Alzheimers disease appears to be in accordance with the distribution of butyrylcholinesterase seen in postmortem studies of human brain, except for an observed higher activity in striatum than in cortex
