PET/CT in Radiation Therapy Planning for Breast Cancer

PET/computed tomography-based imaging is a valuable and useful test in the staging and restaging of breast cancer, especially in patients who have recurrent or locally advanced breast cancer. Its greatest clinical applications are in the detection and definition of the extent of recurrent or metastatic disease. However, the potential to improve radiation treatment planning by allowing for the tailoring of comprehensive radiation portals, particularly for locally advanced or recurrent breast cancer, makes it one of the most promising tools in the era of image-guided radiation therapy.
