PET instrumentation and methodology

PET. It also has a relatively long half-life of 110 minutes, which means that it is practical to use and particularly well suited to clinical application. FDG is by far the most popular tracer used for current clinical applications, primarily because it can exploit the fact that malignant tumors tend to exhibit elevated glucose metabolism compared with normal tissue. However, a major strength of PET is the potential for the development of new tracers that will satisfy evolving clinical needs and research interests. Increasingly, new radiotracers labeled with 18F are being developed with the potential for more widespread distribution than the shorter-lived positron emitters.
