A brain tumor is an excessive development of abnormal and uncontrolled cells in the brain. This growth considered deadly since it may cause death. The controls numerous functions, such as memory, vision, emotions. Due to location, size, shape these tumors, their detection a challenging complex task. Several efforts have been conducted toward improved yielded promising results outcomes. However,...

This Brain tumors are the mechanisms to control normal cells randomly and uncontrolled multiplication of cells in which growth is an abnormal mass of tissue. A tumor growth takes place within the skull and interferes with normal brain activity. Therefore, the first step is very important in tumor detection. Various techniques have been developed to detect tumors in the brain. Most crucial task ...

Brain tumor is the most common and deadliest disease that can be found in all age groups. Generally, MRI modality adopted for identifying diagnosing tumors by radiologists. The correct identification of regions its type aid to diagnose with followup treatment plans. However, any radiologist analysing such scans a complex time-consuming task. Motivated deep learning based computer-aided-diagnosi...

purpose: to report a case of spinal cord tumor with visual symptoms and papilledema due to increased intracranial pressure. patient and findings: a 24-year-old woman was referred because of recent blurred vision in both eyes. visual acuity was 20/25 and 20/20 in the right and left eyes, respectively. fundoscopy revealed bilateral papilledema. other ophthalmic examinations were normal. visual fi...

The 2021 World Health Organization (WHO) classification of brain tumors,[1] as a follow-up to the 2016 update, incorporates validated molecular markers previously established histomorphological features and has led significant shift in diagnosis management adult diffuse gliomas. provides distinction between astrocytoma Isocitrate Dehydrogenase (IDH) mutant grade 4 IDH-wildtype glioblastoma, whi...

Using image segmentation techniques to assist physicians in brain tumor diagnosis is a hot issue computer technology research. Although most networks date have been based on U-Net, the prediction results are depending which not well generalized and need be further improved. As depth of network increases, gradients vanish together with decrease accuracy; meanwhile, large number parameters will c...

Glioblastoma is one of the most common and lethal primary neoplasms brain. Patient survival has not improved significantly over past three decades patient median just year. Tumor heterogeneity thought to be a major determinant therapeutic failure reason for poor overall survival. This work aims comprehensively define intra- inter-tumor by mapping genomic mutational landscape multiple areas IDH ...

 Primary and secondary malignant central nervous system (CNS) tumors are devastating invasive tumors able to give rise to many kinds of differentiated tumor cells. Glioblastoma multiform (GBM), is the most malignant brain tumor, in which its growth and persistence depend on cancer stem cells with enhanced DNA damage repair program that also induces recurrence and resists current chemo- and radi...

Today, high mortality rates due to brain tumors require early diagnosis in the early stages to treat and reduce mortality. Therefore, the use of automatic methods will be very useful for accurate examination of tumors. In recent years, the use of FMRI images has been considered for clarity and high quality for the diagnosis of tumor and the exact location of the tumor. In this study, a complete...
