ABSTRACT
Ensuring safety while maximizing the imaging efšciency (i.e., clinically useful imaging information over time) is an integral part of diagnostic imaging. Safety standards have been set by regulatory agencies and recommended by additional scientišc groups to ensure safety during imaging. This chapter reviews the existing safety standards and their rationale for the commonly used diagnostic imaging modalities in omics of positron emission tomography (PET), single-photon emission computed tomography (SPECT), computed tomography (CT), and magnetic resonance imaging and spectroscopy (MRI and MRS). Current knowledge gaps and research opportunities are discussed to maximize imaging efšciency safely.
