In this review, the fundamental principles of fluorodeoxyglucose (FDG) positron emission tomography (PET) and FDG PET/computed tomography (CT) imaging have been described. The basic physics of PET instrumentation, radiotracer chemistry, and the artifacts, as well as normal physiological or benign pathological variants, have been described and presented to the readers in a lucid manner to enable them an easy grasp of the fundamentals of the subject. Finally, we have outlined the current developments in quantitative PET imaging, including dual time point and delayed PET imaging, time-of-flight technology in PET imaging and partial volume correction, and global disease assessment with their potential of being incorporated into the assessment of benign and malignant disorders.
