SUVmax is an index of accumulation in FDG-PET, and is expected to be a prognostic factor of various cancer. However, it is a relative index and is affected by tumor size, respiratory movement, tumor background, instrument and so on. We made an experiment using moving phantom and tried to correct SUVmax modified with tumor size and respiratory movement. Next, availability of the corrected SUVmax was investigated on the treatment results data of stereotactic body radiotherapy for patients with non-small cell cancer.As results, actual SUVmax and corrected SUVmax were correlated well with local control and disease-free control. However, corrected SUVmax was not shown to be more correlated with those outcomes.
