The meningioma brain tumor detection is more important than the other tumor detection such as Glioma and Glioblastoma, due to its high severity level. The tumor pixel density of meningioma tumor is high and it leads to sudden death if it is not detected timely. The meningioma images are ...
Meningiomas are the most commonly reported intracranial tumor. They represent approximately 38% of all intracranial neoplasms in females and 20% in males. Meningiomas are also the most common extra-axial tumors in the brain and the most frequently occurring tumors of mesodermal or meningeal origin. ...
Magnetic resonance imaging (MRI) of the brain (Fig.1) revealed a nodular mass involving the left cavernous sinus extending to the Meckel cave and the pituitary gland. The mass was isointense to gray matter in T2- and T1-weighted images and enhanced homogeneously in postcontrast T1-weighted ...
Recently, the role of NRF2 and its regulatory mechanisms in the ferroptosis of the most malignant brain tumors, glioblastoma (GBM), has garnered significant attention. NRF2 expression in gliomas were found positively correlated with WHO grades [37]. Several mechanisms regulating NRF2 or the KEAP1/...
Magnetic resonance images (MRI) of the brain showed inhomogeneously enhancing mass in the right frontoparietal area which has irregular margin and perilesional edema. Based on the radiological findings, a preoperative diagnosis was an intraaxial tumor, such as pilocytic astrocytoma or dysembryoplastic ...
Second, 68 Ga-DOTA(TOC/NOC/TATE) PET-CT provides high-contrast images of meningiomas due to the abundance of somatostatin receptor 2 in meningiomas but not in brain (except the pituitary gland) and bone. PET-CT has shown to be more sensitive than MRI to detect meningiomas [194, 195] and...
Hyperacute changes in glucose metabolism of brain tumors after stereotactic radiosurgery: A PET study Cultured tumor cells show a marked increase in deoxyglucose uptake as early as 3 h after single high-dose irradiation, reflecting hyperacute response of th... I Maruyama,N Sadato,A Waki,... ...
Preoperative and noninvasive prediction of the meningioma grade is important in clinical practice, as it directly influences the clinical decision making. What’s more, brain invasion in meningioma (i.e., the presence of tumor tissue within the adjacent brain tissue) is an independent criterion for...

摘要: We describe a patient with metastatic disease to an intracranial meningioma in which MR images showed multiple foci of intense enhancement within a background of moderate enhancement. The discrete foci proved to be metastatic disease from the patient's known breast carcinoma....
