"Advances in Polarized Nuclear Imaging"


David Keder , University of Virginia - Physics
[Host: Gordon Cates]
ABSTRACT:

Polarized Nuclear Imaging (PNI) is a novel modality in which images of certain radioactive tracers are formed using conventional Magnetic Resonance Imaging (MRI) techniques by detecting asymmetries in gamma ray emission rates with respect to the nuclear magnetic moments of the tracer.  This modality combines the spatial resolution and contrast provided by MRI with the detection sensitivity of nuclear imaging, allowing for the production of an image using many orders of magnitude fewer nuclei than would be necessary with conventional MRI.  However, many challenges remain in bringing PNI from the laboratory to practice in a clinical setting.  For example, the first PNI image produced took 60 hours to acquire.  In my talk I will describe some novel techniques in currently in development intended to bridge the gap between laboratory and clinic.
