Despite the extensive research efforts over the past century, glioblastoma multiforme (GBM) remains an ominous diagnosis leading fast to progressive disability and death despite the aggressive treatment including microsurgical resection, chemotherapy, radiotherapy and stereotactic radiosurgery. Advanced neuroimaging techniques, such as volumetric acquisitions, spectroscopy, diffusion and perfusion studies added to conventional imaging, provide in selected cases a non-invasive alternative to pathological diagnosis but they are also precious tools to define the boundaries of image-guided microsurgical resection and/or radiosurgical ablation. This paper reviews the role of advanced neuroimaging techniques in the diagnosis and treatment of GBM.

Glioblastoma multiforme (GBM) is the most common and most malignant primary brain tumor occurring during adulthood. The incidence of GBM is nearly 5 cases per 100,000 population per year. ⋯ Imaging modalities used in nuclear medicine, namely positron emission tomography (PET) and single-photon emission computed tomography (SPECT) have been employed towards the evaluation of brain tumors. Herewith, we discuss the value of the above imaging techniques in the assessment of GBM aggressiveness, in the distinction of treatment induced necrosis from glioma recurrence, in the estimation of overall prognosis and in the evaluation of treatment response in patients with GBM.
