The Chemical Eyes of PET (Positron Emission Tomography)

How Chemistry Has Enhanced Scientists’ Ability To See Inside The Brain And Image Studies In Addiction. ‘Molecular imaging using positron emission tomography (PET) continues to provide new knowledge about how brain circuits are altered by addictive drugs. Chemist Joanna Fowler, Director of the Center for Translational Neuroimaging at the U.S. Department of Energy’s Brookhaven National Laboratory and a pioneer in the development of radioactively “tagged” molecules used with PET, gave a talk on these radiotracers at the 232nd national meeting of the American Chemical Society in San Francisco, California, on September 14, 2006, the Moscone Convention Center.’

Positron Emission Tomography (PET) Is The Most Sensitive And Specific Technique For Imaging Molecular Pathways In Vivo In Humans. ‘Research and Markets has announced the addition of “Cytogenetics” to their offering. This report deals with cytogenetics in a broader sense rather than the classical use mainly to describe the chromosome structure and identify abnormalities related to disease. In the age of molecular biology, it is also referred to as molecular cytogenetics. Technologies encompassed within molecular imaging include optical imaging, magnetic resonance imaging (MRI) and nuclear medicine techniques. Positron emission tomography (PET) is the most sensitive and specific technique for imaging molecular pathways in vivo in humans. Cytogenetics can be refined by application of cytogenetics at single molecule level.’
