Advanced MR techniques in brain tumor imaging
Tomography, X-Ray Computed
Advanced magnetic resonance imaging (MRI) techniques, such as spectroscopy, perfusion, and functional imaging, have improved the imaging of brain tumors. In addition to the anatomic or structural information available with conventional MRI, advanced MRI techniques also provide physiologic information about tumor metabolism and hemodynamics. The authors review the physiology, techniques, and clinical applications of perfusion MRI, spectroscopy, functional MRI, and diffusion tensor imaging in the setting of neuro-oncology.
