GROUP 1: All patients with newly diagnosed intra-axial brain neoplasms undergo volumetric MRI study with contrast for surgical planning or clinical diagnosis. Diffusion, diffusion tensor imaging and perfusion imaging are often performed as a part of standard clinical imaging. In addition to these acquisitions, the research 3D-MRF acquisition through the entire tumor will be acquired. The imaging parameters will be correlated individually and in combination with biopsy/ resection outcomes.
