Abstract See Fujita and Eidelberg (doi: 10.1093/brain/awx305) for a scientific commentary
on this article. Focal dystonias are the most common type of isolated dystonia. Although their …

INTRODUCTION: Carbon-11-labelled positron emission tomography (PET) tracers
commonly used in biomedical research expose subjects to ionising radiation. Dosimetry is …

Before a new tracer can be used in clinical research, it is customary to perform dosimetry
scans in animals and humans to assess whether the radiation exposure is acceptable. The …

Abstract Purpose Methyl-11 C-choline ([11 C] choline) is a radiopharmaceutical used for
oncological PET studies. We investigated the biodistribution and biokinetics of [11 C] choline …

Dear Sir, Before a new radioactive tracer can be used in humans, many national as well as
local Institutional Radiation Safety Committees often require that a biodistribution study be …

The present study estimated the biodistribution and radiation-absorbed dose of epidermal
growth factor receptor (EGFR) radioligand 11C-PD153035 in whole-body PET examinations …

Our laboratory developed (S)-3-(2′-fluoro-6′, 7′-dihydrospiro [piperidine-4, 4′-thieno
[3, 2-c] pyran]-1-yl)-2-(2-fluorobenzyl)-N-methylpropanamide (11C-NOP-1A), a new …

Purpose The positron emission tomography (PET) radiotracer 11 C-(R)-PK11195 allows the
in vivo imaging in humans of the translocator protein 18 kDa (TSPO), previously called …

Dopamine is a small molecule traditionally regarded as a brain-derived neuronal modulator
implicated in many neurological and psychiatric disorders. Outside the brain, dopamine …

Objective To evaluate the biodistribution of radiation-absorbed doses of 13 N-ammonia in
healthy people. Methods Five healthy human subjects underwent whole-body PET and CT …
