Scientific summary
During my 1992-1996 PhD program, I developped and validated on test object (ie EUROSPIN) and in vivo, a rapid relaxation times measurement method by MRI (MRI-quantitative method) and a simulation method to evaluate the contrast in MRI with the aim to optimize the use of contrast media in clinical imaging. In collaboration with INRA-Theix, these method were applied to characterize in vivo rabbit muscle fiber types. Since 2000, I developped and applied the MRI-quantitaive method in two ways : (i) to verify the 3D dose distribution delivered by radiotherapy beams using a new 3D chemical dosimeter with MRI reading in collaboration with French national laboratory of metrology (LNHB) and Paul Sabatier University ; this method will be able to measure precisely (2 mm) the 3D dose for new treatment modalities such as IMRT and stereotactic conditions (Euramett Project, JPR14 2012 accepted) and (ii) to develop and validate by multicenter clinical trial a physiological tumor parameters quantification by dynamic relaxometry MRI ; the objective of this method is to have a more effective prediction of tumour response to radiation therapy and to improve efficiency of MRI diagnosis : benign vs malignant tumour. In CREaT team, this MRI approach contributes to the spatial tumour targeting in combination with biological targeting.
