“Hyperpolarized 129Xe Magnetic Resonance Imaging for Evaluation of Radiation-Induced Lung Injury in Subjects Undergoing Thoracic Irradiation”
The purpose of this work is to perform hyperpolarized (HP) 129Xe MRI in human subjects undergoing thoracic radiation therapy (RT), both before, during and following RT. HP 129Xe MR images will be analysed to provide maps of ventilation (V), perfusion (Q), apparent diffusion coefficient (ADC) and gas exchange. These results will be combined to yield a new measure of RILI, (i.e. dose volume histograms; DVHV/Q) and compared with conventional dose volume histograms (DVH), pulmonary function tests (PFTs), quality of life (QOL) questionnaire and CT measurements for assessment of RILI at each time point. The aim is to development a novel method for early and more sensitive method of detecting RILI before irreversible lung damage happens.
