In this study, we evaluate the role of diffusion kurtosis imaging (DKI) and MR spectroscopy (MRS), two advanced imaging techniques in magnetic resonance (MR) in grading and detection of microscopic infiltrating tumour in gliomas. These parameters are of utmost importance in optimal choice and planning of treatment.

Patients treated with gliomatous brain tumours are included voluntarily. They undergo one imaging session on a 3T MR scanner prior to treatment.

DKI data are quantitively analyzed in order to estimate specific parameters in normal appearing white matter, grey matter, tumor and peritumoral edema. MRS data are analyzed quantitatively and qualitatively with peak integration, ratio calculation and classification algorithms. Histological confirmation is obtained at subsequent surgery.

Information from this study can be of significant importance in avoiding brain biopsies. Furthermore, information on microscopic tumour spread can be used during neurosurgery or in radiotherapy planning. An important advantage of these advanced MR techniques is the non-invasivity and the lack of ionizing radiation, two important issues in this relatively young patient population.
