This prospective study sought to determine how the use of combined PET/CT for radiotherapy treatment planning of oesophageal cancer would alter the delineation of tumour volumes compared to CT alone if PET/CT is assumed to more accurately represent true disease extent.All patients underwent FDG-PET/CT scanning in the radiotherapy treatment position. For each patient, two separate gross tumour volumes...
Tumor hyperoxygenation results in high response rates to ARCON (accelerated radiotherapy with carbogen and nicotinamide). The effect of hyperoxygenation on tumor metabolism using [ 18 F]fluorodeoxyglucose (FDG) positron emission tomography (PET) was investigated.Within one week, FDG-PET was performed without and with hyperoxygenation by carbogen breathing and/or nicotinamide administration...
