The brain tumor is abnormal growth of cells inside skull which causes damage of the other cells necessary for functioning human brain. The brain tumor detection is challenging task due to complex structure of human brain. MRI images generated from MRI scanners using strong magnetic fields and radio waves to form images of the body which helps for medical diagnosis. This paper gives the overview...

Primary malignant brain tumors account for 2 percent of all cancers in U.S. adults. The most common malignant brain tumor is glioblastoma multiforme, and patients with this type of tumor have a poor prognosis. Previous exposure to high-dose ionizing radiation is the only proven environmental risk factor for a brain tumor. Primary brain tumors are classified based on their cellular origin and hi...

Glioblastoma (GBM), the most common and lethal primary brain tumor in adults, requires multi-treatment intervention which unfortunately barely shifts needle overall survival. The treatment options after diagnosis surgical resection (if possible) include irradiation, temozolomide (TMZ) chemotherapy, now treating fields (TTFields). TTFields are electric delivered locoregionally to head/tumor via ...

Brain tumors are one of the deadliest cancers in world. Researchers have conducted a lot research work on brain tumor segmentation with good performance due to rapid development deep learning for assisting doctors diagnosis and treatment. However, most these methods cannot fully combine multiple feature information their performances need be improved. This study developed novel network fusing l...

The use of quantitative mapping diffusion characteristics carries great potential for diagnosis and therapy brain diseases, since it potentially allows to classify tumors, determine the degree their malignancy, differentiate various morphological structures tumor non-tumor pathologies (such as stroma, necrotic zones, cysts, types edema, etc.), predict course outcome in particular, a clinical re...

Introduction: The most common primary tumors of brain are gliomas and tumor grading is essential for designing proper treatment strategies. The gold standard choice to determine grade of glial tumor is biopsy which is an invasive method. The purpose of this study was to investigatethe role of fiber density index (FDi) by means of diffusion tensor imaging (DTI) (as a noninvasive method) in glial...

We describe a 51-year-old woman with a cerebral infarction that showed transient accumulation of thallium-201. On admission, this lesion was well-enhanced by gadolinium injection and gradually expanded, mimicking a malignant brain tumor. A cerebral angiogram, however, did not indicate the presence of a malignant brain tumor. Ethyl cysteinate dimer single photon computerized tomography showed pe...

Abstract BACKGROUND Differentiating neoplastic and non-neoplastic brain lesions is essential to make management recommendations convey prognosis, but the distinction between tumors their mimics in practice may prove challenging. The aim of this study provide incidence tumor neuro-oncology setting describe patient subset. METHODS Retrospective adult patients referred Division Neuro-oncology for ...

Introduction Brain tumor is due to the growth of abnormal cells in the brain. Brain tumor in its final stage is converted as brain cancer, which leads to death. Survival rate can be increased if the tumor is detected and diagnosed in the initial stages. The detection of the tumor in MR images of the brain can be done using segmentation. These brain tumors exist in different types which make the...
