Differentiation of radiation necrosis (RN) from recurrent tumor (RT) in treated patients with glioblastoma remains a diagnostic challenge. The purpose of this study is to evaluate the diagnostic performance of multiparametric MRI in distinguishing RN from RT in patients with glioblastoma, with the use of a combination of MR perfusion and diffu-sion parameters. MATERIALS AND METHODS.

MR perfusion imaging will be performed in addition to the routine neuronavigational sequence obtained from re-operative/therapy planning. Following MR examination, yielding valuable diagnostic information in differentiating radiation necrosis from tumour recurrence,

36 Keywords: glioblastoma, MR diffusion, MR perfusion, posttreatment change, radiation necrosis Radiation therapy is part of the standardized treatment of patients with glioblastoma and can lead to radiation necrosis (RN) that may manifest as progressive contrast enhancement on follow-up MRI [2, 3]. Radiation necrosis in the brain commonly occurs in three distinct clinical scenarios, namely, radiation therapy for head and neck malignancy or intracranial extraaxial tumor, stereotactic radiation therapy (including radiosurgery) for brain metastasis, and radiation therapy for primary brain tumors.

Radiology 2009; 253:486–96. Purpose: This meta-analysis examined roles of several metabolites in differentiating recurrent tumor from necrosis in patients with brain tumors using MR perfusion and spectroscopy. Methods: Medline, Cochrane, EMBASE, and Google Scholar were searched for studies using perfusion MRI and/or MR spectroscopy published up to March 4, 2015 which Corpus ID: 209314940.

The distinction between radiation necrosis and recurrent high-grade glioma remains a challenge despite advanced imaging techniques such as perfusion- and diffusion-weighted MR imaging (1–5), MR spectroscopy , and positron emission tomography (7–9). Advanced imaging modalities such as diffusion tensor imaging and perfusion MR imaging (with calculation of certain specific parameters such as apparent diffusion coefficient ratios, relative peak height, and percentage of signal recovery), MR spectroscopy, and positron emission tomography can be useful in differentiating between recurrent tumor and radiation necrosis.
