Title: Introduction and clinical application of PET/CT for oncologists
Biography: Jae Pil Hwang
In recent decades, 18F–fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) is non-invasive imaging modality and has been routinely used for diagnosis, staging, restaging, assessing treatment response, detecting recurrence after treatment and evaluating prognosis of patients in various malignancies.
Because tumor FDG uptake is associated with tumor aggressiveness, positive tumor FDG uptake on visual analysis and intensity of uptake, expressed as maximum standardized uptake value (SUVmax), volumetric parameters including metabolic tumor volume (MTV), total lesion glycolysis (TLG) and intratumoral heterogeneity reflecting the biological tumor conditions such as metabolism, hypoxia, necrosis, and cellular proliferation.
In this forum, we overview the introduction and clinical applications of oncologic PET/CT that investigated metabolic characteristics on various cancers, and we discuss the clinical roles of PET/CT for patients with malignant disease and for clinical oncologists. Although FDG continues to be the most widely used radiotracer for PET imaging, some of the another or newer PET imaging agents that have been studied in humans will also be announced
