Positron emission tomography: Evolving modalities, radiopharmaceuticals and professional collaboration

Abstract

Abstract Positron emission tomography (PET) as an imaging modality has undergone considerable innovation over the past few decades. Hybrid anatomical and functional imaging has become commonplace (initially PET/CT but now also PET/MRI) with improvements in imaging technology continually delivering studies with increasing diagnostic accuracy and decreasing radiation dose to the patient. More and more radiopharmaceuticals have emerged from the research sphere into clinical practice, with the traditional PET workhorse tracer 18F‐FDG accompanied by a range of novel radiopharmaceuticals with specific molecular targets. Imaging facilities offering PET/CT and PET/MRI provide a unique collaborative environment for the medical imaging multidisciplinary team. Diagnostic radiographers and nuclear medicine technologists especially have the opportunity to not only work together but also share knowledge and technical skills, ultimately benefitting the quality of patient care.
