| CBIC-A2 ... MRI Safety for Imaging/Healthcare Personnel
Recommended reading for anyone working in the MRI environment
‘The MRI suite poses special safety risk since the magnet is over... [60,000 at 3T]... times the earth’s natural magnetic pull. Because the magnet is always “on” those who approach the magnetic field must have training. This module discusses the special considerations of MRI safety that Radiographers, Nurses, Patient Transport, Custodial care professionals and the like should understand and practice concerning MR safety. Patient safety concerns such as pacemakers and metallic devices related to imaging are also discussed.

| Simultaneous microPET/microMRI Imaging Development and Applications
The ideal biological imaging system would provide non-invasive, high-resolution, high-sensitivity, three-dimensional (3D) images of living systems. Positron Emission Tomography (PET) offers high sensitivity to a range of biological processes through the use of targeted radiolabeled probes. Unfortunately, precise signal localization can be extremely difficult due to low spatial resolution and the lack of anatomical information. Magnetic Resonance Imaging (MRI) can provide high spatial resolution and excellent soft tissue contrast, but suffers from poor signal strength leading to low sensitivity. The specific aim of this proposal is to combine the best features of each modality into a single imaging instrument that will record data in both imaging modalities simultaneously. Moreover, we will develop labeled probes that can be detected in both PET and MRI to aid in the interpretation of complex biological processes.
