Diagnostic accuracy of 11C-methionine PET for differentiation of recurrent brain tumors from radiation necrosis after radiotherapy.
UNLABELLED We evaluated the diagnostic accuracy of PET with l-methyl-(11)C-methionine ((11)C-MET) for the differentiation of recurrent brain tumors from radiation necrosis. METHODS Seventy-seven patients who had been previously treated with radiotherapy after primary treatment for metastatic brain tumor (n=51) or glioma (n=26) were studied to clarify the diagnostic performance of (11)C-MET PE...
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 کاملDifferentiation of Brain Tumor Recurrence from Post-Radiotherapy Necrosis with 11C-Methionine PET: Visual Assessment versus Quantitative Assessment
PURPOSE The aim of this multi-center study was to assess the diagnostic capability of visual assessment in L-methyl-11C-methionine positron emission tomography (MET-PET) for differentiating a recurrent brain tumor from radiation-induced necrosis after radiotherapy, and to compare it to the accuracy of quantitative analysis. METHODS A total of 73 brain lesions (glioma: 31, brain metastasis: 42...
متن کاملComparison of magnetic resonance spectroscopy and diffusion weighted imaging in the differentiation of glioma recurrence from radiation necrosis: meta-analysis
Aim: The purpose of this study was to compare the diagnostic accuracy of diffusion-weighted magnetic resonance imaging (DWI) and magnetic resonance spectroscopy (MRS) for the diagnosis of differentiating glioma recurrence from radiation necrosis through a meta-analysis. Methods: We performed a meta-analysis of all available studies of the diagnostic performance of DWI and MRS for differentiatin...
متن کاملExploration of the recurrence in radiation brain necrosis after bevacizumab discontinuation
OBJECTIVE The aim of the paper was to investigate the recurrence and its causes of radiation brain necrosis following bevacizumab discontinuation. METHODS This study included 14 patients with radiation brain necrosis (confirmed through imaging) after stereotactic radiotherapy for a primary or metastatic brain tumor and who received bevacizumab treatment from June 2011 through December 2014. T...
