Imaging comes of age in biomedical research

March 10, 2008 Imaging comes of age in biomedical research Philip Ward Radiologists must develop strategies for participating in the new age of imaging-based research. They need to join interdisciplinary teams, develop core imaging facilities for host institutions, involve themselves in small-animal imaging facilities, enter clinical research programs, and learn about PET and molecular imaging, which are at the core of pharmaceutical development. This was the advice of Prof. James H. Thrall,… Continue
