Application and development of PET/CT in radiotherapy for non-small cell lung cancer / 中国医学装备

ABSTRACT

Radiation therapy is one of the main means of treatment for non-small cell lung cancer (NSCLC). With the rapid development of modern technology, three dimensional conformal radiotherapy, intensity modulated radiotherapy, stereotactic radiotherapy play a very important role in this field. The use of the state-of-art radiation modality can definitely improves the accuracy of the treatment, which results in improving the local control rate of tumor and reducing the adverse reaction of normal tissue. Advances in modern imaging device and its clinical application is the premise of precise radiotherapy. Positron emission tomography and computed tomography (PET-CT) can effectively provide anatomical and functional information; it plays a more and more important role in the diagnosis of NSCLC before radiotherapy, the process of precise target delineation and also the evaluation of therapeutic efficacy after radiotherapy.
