As physicians strive for earlier and more accurate detection of neurological disorders, cardiovascular disease and cancers, positron emission tomography/computed tomography (PET/CT) molecular imaging innovations play an essential role in revealing the complete picture of the disease. Unlike conventional anatomic medical imaging, PET/CT enables physicians to visualize biological processes at the cellular level, where disease begins. The widespread availability of PET/CT technology has led to the significant growth and acceptance of molecular imaging over the past several years, according to Michael Casey (60), a developer of PET devices. Casey has helped to create numerous inventions relating to PET/CT, many of which have accelerated patient scan times and improved image quality—contributing to enhanced patient care. Casey works at Siemens Healthcare in Tennessee, U.S.
