Role of PET-CT in the optimization of thoracic radiotherapy

Abstract

PET-CT is an exciting new imaging technology that simultaneously acquires detailed structural and functional imaging information. PET is having an increasing inpact on the management of locoregionally advanced non-small cell lung cancer with radiotherapy. PET combined with CT is much more accurate than CT alone in staging lung cancer and patients treated with radical radiotherapy or chemoradiotherapy have better outcomes because of superior patient selection. PET also has the potential to improve radiotherapy planning by minimizing unnecessary irradiation of normal tissues and by reducing the risk of geographicmiss. PET influences treatment planning in a high proportion of cases and therefor..
