Glioblastoma is a malignant primary brain tumor that is highly invasive and infiltrative. Surgical resection and radiation therapy are not able to remove all tumor cells. Consequently, residual tumor is found in the majority of patients after surgery, causing early recurrence and decreased survival. Magnetic Resonance Imaging (MRI) is routinely used in the diagnosis, treatment planning and monitoring of glioblastoma. The contrast-enhancing region identified with MRI is generally used to guide surgery and to provide a reference for radiotherapy planning. While edema and non-enhancing regions surrounding the tumor are
potential sites of tumor infiltration, usually they are not included in surgical resection as routine MRI cannot differentiate tumorous tissues in those regions.
UC Berkeley researchers have developed a novel MRI technique that can identify, non-invasively and in-vivo, areas of altered iron metabolism associated with tumor activities in the edema tissue surrounding glioblastoma. The technique uniquely delineates a hyperintense area within the edema. The method can be used to guide surgery and radiotherapy and to monitor treatment response.
