This Research Topic is the Second Volume of the Research Topic Advances in PET-CT ImagingPositron emission tomography combined with computed tomography (PET-CT) is an advanced medical imaging technique that allows the visualization of molecular processes and anatomical structures within the body. PET-CT is primarily applied for the diagnosis and staging of various types of cancers, as well as for clinical examinations of inflammatory, cardiac, and neurodegenerative diseases. While PET-CT offers numerous advantages, such as high accuracy and efficiency in the diagnosis of diseases, it also presents some limitations, including a spatial resolution of 4 to 5 mm, which hinders the detection and characterization of small lesions, as well as artifacts caused by respiratory motion, contrast medium, and metal. Additionally, the high cost of equipment and radiotracers poses another challenge that needs to be overcome.This Research Topic focuses on developing and implementing innovative approaches within clinics and research settings to overcome the current challenges in PET-CT scanning. It involves the optimization of current PET-CT protocols, hardware upgrades, the design and implementation of new algorithms in the software, the integration of artificial intelligence techniques, as well as the development and application of novel radiotracers.This Research Topic aims to explore the advancements and challenges in PET-CT imaging, with a focus on innovative approaches to overcome current limitations. We encourage contributors to address topics such as the optimization of PET-CT protocols, hardware upgrades, the development and application of new algorithms in software, and the design of novel radiotracers. We welcome studies that present novel techniques, share clinical experiences, discuss technological advancements, and propose future directions for PET-CT imaging. Authors are encouraged to provide insights into the impact of these advancements on patient outcomes, early disease detection, personalized treatment strategies, and the expansion of PET-CT applications in clinical practice.
