IVIM Diffusion MRI analysis and biomarkers for chemotherapy

MR perfusion imaging, techniques and role in differentiating radiation necrosis and tumor recurrence. Zakaria R(1), Mubarak F(1), Shamim MS(1). Author information: (1)Department of Surgery, Aga Khan University Hospital, Karachi. 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 Differentiating Radiation-Induced Necrosis from Recurrent Brain Tumor Using MR Perfusion and Spectroscopy: A Meta-Analysis. Ming-Tsung Chuang, Yi-Sheng Liu, Yi-Shan Tsai, Ying-Chen Chen, and Chien-Kuo Wang * Jeroen Hendrikse, Editor 2016-01-07 In patients with a history of radiation therapy for extracranial or extraaxial tumors, radiation necrosis in the brain may be identified using magnetic resonance (MR) imaging supported by perfusion MR imaging, MR spectroscopy, and positron emission tomography (PET), … 2019-04-15 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.

Calling it "one-stop shopping" imaging, researchers at NYU's Kaplan Comprehensive Cancer Center are touting perfusion-based MRI as an effective method for distinguishing recurrent brain tumors from radiation necrosis.

MR perfusion imaging, techniques and role in differentiating radiation necrosis and tumor recurrence. 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.

This approach allows hemodynamic measurements to be obtained within the brain as the relative cerebral blood volume (rCBV) to complement the anatomic information obtained with conventional contrast enhanced MR imaging. 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 Objective: 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 diffusion parameters. These maps can also potentially be used to localize areas of tumor more likely to yield positive results on stereotactic biopsy and to noninvasively differentiate radiation necrosis from recurrent tumor in circumstances in which conventional MR findings are equivocal [45, 46] (Figs.

In contrast, tumor recurrence promotes angiogenesis and microvascular proliferation, helping to sustain tumor growth. 2009-09-01 2018-09-01 2019-02-06 Arterial spin labeling (ASL) magnetic resonance (MR) perfusion imaging has been proposed as an effective method to measure brain tumor perfusion.
