Pet-Ct Based Radiotherapy Planning

With the advent of advanced imaging techniques such as positron emission topography/computed topography, use of radiotherapy in the management of various cancers has become more effective and is shown to have better outcomes. PET/CT scanning is useful for evaluating tumour biological heterogeneity of malignant lesions providing comprehensive information regards the tumour’s metabolism, hypoxia, and proliferation. Integration of PET/CT imaging in radiotherapy helps in assessing tumour volume to achieve effective tumour control by adjusting radiation dose. Literature is extensive on PET/CT based radiation planning and here we aim to provide a brief review of PET/CT use in different malignancies.
