The differences of MR spectroscopic imaging and MR diffusion weighted imaging parameters in different subtypes of grade 3 gliomas

In this study, we analyzed the MR spectroscopic and MR diffusion weighted imaging parameter differences among the subtypes of grade 3 brain tumor patients (anaplastic astrocytoma, oligodendroglioma, and oligoastrocytoma). We observed higher lipid values in the tumor regions of oligodendrogliomas than both astrocytomas and oligoastrocytomas. According to these results, there were not significant MR spectroscopic or MR diffusion differences between the subtypes of grade 3 brain tumors for this patient population and except lipid it would be acceptable to combine the data of these subgroups for future studies.
