摘要: Molecular imaging, in particular, PET, has brought an additional dimension to management for patients with cancer. 18F-FDG, which is the most widely available tracer, been shown be of value selection target volumes radiation oncology. Depending on its sensitivity and specificity, 18F-FDG influence non-small cell lung cancers (NSCLC) or esophageal tumors. On other hand, tumors such as head neck squamous carcinomas (HNSCC) rectal carcinomas, convincing data volume are still lacking. For delineation, given that adequate method used segmentation, added demonstrated HNSCC NSCLC. both types tumors, modifications delineation translated into differences dose distribution compared results CT scan-based plans. Studies progress Novel markers tumor hypoxia proliferation have potential modify volumes, allowing "dose painting" selected subvolumes. Finally, variations viability during radiotherapy also under intense investigation, potentially paving way so-called "theragnostic" adaptive treatment. This review discusses how PET/CT might current state art planning.
