PD-0467: Adaptive, preoperative radiotherapy with image guided Tomotherapy concomitant with chemotherapy in rectal cancer (original) (raw)

S230 3rd ESTRO Forum 2015 Conclusions: This meta-analysis demonstrates Level-II evidence of the high diagnostic performance of MRI in staging hilar/mediastinal LNs in NSCLC on both per-patient and pernodal basis. Relative to FDG-PET/CT, pulmonary MRI is able to reach higher sensitivity at similar specificity, encouraging future prospective studies on treatment decision-making and selective nodal irradiation in NSCLC. However, before pulmonary MRI can replace FDG-PET/CT in NSCLC radiotherapy, thorough assessment of geometric distortion in MR images is mandatory.
