The document discusses the benefits of PET/CT imaging over PET-only or CT-only imaging. PET/CT provides both anatomical and functional information in a single exam, improving diagnostic accuracy and treatment planning. It allows physicians to better detect, diagnose, and monitor a variety of cancers and other diseases. The document provides several clinical cases that demonstrate how PET/CT altered patient management decisions and led to improved outcomes.
