　　The ongoing development of advanced anatomical and physiological MRI techniques continues to aid in the diagnosis and management of primary brain tumors.Anatomical MRI continues to improve, for example with 3D volumetric imaging and semiautomated tumor volume calculations.Physiological MRI techniques such as perfusion imaging, diffusion imaging, and MR spectroscopy contribute to initial diagnosis and grading.These techniques hold promise in predicting tumor biological activity to rival or surpass histopathological grading.For example, data suggest that the relative cerebral blood volume parameter of perfusion imaging (rCBV) predicts time to progression in gliomas independent ofhistopathological findings (M.Law et al., Radiology 2008:247:490-498).
