The Current Role of PET/CT in Radiotherapy Planning.

Positron Emission Tomography (PET) is increasingly being used in radiotherapy planning, with the development of hybrid imaging technology such as PET/CT allowing more accurate volumes being generated for treatment with external beam radiation. This article will discuss the use of FDG PET in radiotherapy planning of various types of malignancies, as well as some pitfalls and practicalities of integrating PET/CT into radiotherapy planning.
