متن کاملComparison of brain SPECT with 99mTc-MIBI and CT-scan in discriminating of radiation necrosis and brain tumor recurrence [Persian]
Introduction: 99mTc-MIBI has been proposed for use as an imaging agent for various tumors, including breast cancer, lung cancer, lymphomas, melanomas and brain neoplastic lesions. Brain tumors are very common and radiotherapy being major part of treatment following surgery. After radiotherapy, deteriorating clinical status can be due to either radiation necrosis or recurrent tumor. Comput...
متن کاملDifferentiation of Tumor Recurrence from radiation-induced Necrosis Using Diffusion Tensor Imaging
Introduction: Surgical resection and chemotherapy alone have proven to be insufficient in treatment of patients with primary and metastatic brain tumors. As a result, the various forms of radiotherapy, such as external-beam radiation, radiosurgery have become important therapeutic adjuncts. The appearance of a new enhancing lesion after radiation treatment may represent tumor recurrence, radiat...
متن کاملComparison of 11C-Methionine, 11C-Choline, and 18F-Fluorodeoxyglucose-Positron Emission Tomography for Distinguishing Glioma Recurrence from Radiation Necrosis
The aim of this study is to assess the different metabolic activities characteristic of glioma recurrence and radiation necrosis (RN) and to explore the diagnostic accuracy for differentiation of the two conditions using (11)C-methionine (MET), (11)C-choline (CHO), and (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET). Fifty patients with lesions suggestive of recurrent glioma b...
متن کاملToward distinguishing recurrent tumor from radiation necrosis: DWI and MTC in a Gamma Knife--irradiated mouse glioma model.
PURPOSE Accurate noninvasive diagnosis is vital for effective treatment planning. Presently, standard anatomical magnetic resonance imaging (MRI) is incapable of differentiating recurring tumor from delayed radiation injury, as both lesions are hyperintense in both postcontrast T1- and T2-weighted images. Further studies are therefore necessary to identify an MRI paradigm that can differentiall...
