Diffusion weighted MRI in head-and-neck cancer: geometrical accuracy.

INTRODUCTION The aim of this study is to assess the geometric accuracy of diffusion weighted (DW)-MRI by quantification of geometric distortions in the gross tumor volume (GTV) in head and neck (HN) cancer. MATERIALS & METHODS A retrospective analysis was performed on the data of 23 patients (with 24 lesions). For these patients, magnetic field maps and… CONTINUE READING
