Abstract
Positron emission tomography (PET) scanning, a functional imaging technique, is playing a more and more important role in modern medical science compared to the conventional anatomy imaging technologies such as X-ray and computed tomography (CT), ultrasound, and magnetic resonance imaging (MRI).Though with the help of modern computer technology, the CT, MRI, and ultrasound have begun to be used for functional imaging, the PET scan still has advantages over other imaging modalities.

Many evidences have shown that FDG-PET can be used for diagnosis, staging, and monitoring the treatment of cancers, in Hodgkin's lymphoma, Non-Hodgkin’s lymphoma [4], lung cancer [5], and other solid tumors [4]
Summary
Positron emission tomography (PET) [1] scanning, a functional imaging technique, is playing a more and more important role in modern medical science compared to the conventional anatomy imaging technologies such as X-ray and computed tomography (CT), ultrasound, and magnetic resonance imaging (MRI). Though with the help of modern computer technology, the CT, MRI, and ultrasound have begun to be used for functional imaging, the PET scan still has advantages over other imaging modalities. The most useful application of FDG PET-CT for cancer patients is could detect recurrence, especially in asymptomatic patients with rising tumor marker levels and those with negative or equivocal conventional imaging findings [6].
