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...

background: central nervous system (cns) tumors have accounted for approximately one fourth of all pediatric malignancies. cns tumors have been the most common solid malignancies among the children. in this study, we have evaluated survival and prognostic factors in children with non-brain stem astrocytoma. methods: children with non-brain stem astrocytoma, referring to radiation oncology cente...

background: the touch preparation technique is an accurate and rapid method, and when used as intraoperative consultation examination technique it preserves a good amount of tissue for paraffin embedded sections. this study aimed at examining the accuracy of the touch preparation technique by comparing its diagnosis with that of final pathological diagnosis made by microscopic examinations. met...

A brain tumor consists of cells showing abnormal growth. The area the significantly affects choosing type treatment and following course disease during treatment. At same time, pictures Brain MRIs are accompanied by noise. Eliminating existing noises can impact better segmentation diagnosis tumors. In this work, we have tried using analysis eigenvalues. We used MSVD algorithm, reducing image no...

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...

Brain tumor refers to the formation of abnormal cells in brain. It can be divided into benign and malignant. The main diagnostic methods for brain tumors are plain X-ray film, Magnetic resonance imaging (MRI), so on. However, these artificial diagnosis easily affected by external factors. Scholars have made such impressive progress classification using convolutional neural network (CNN). there ...

Artificial intelligence (AI) is rapidly integrating into diagnostic methods across many branches of medicine. Significant progress has been made in tumor assessment using AI algorithms, and research underway on how image manipulation can provide information with diagnostic, prognostic treatment impacts. Glioblastoma (GB) remains the most common primary malignant brain tumor, a median survival 1...

Glioma is the most common type of brain tumor and according to the 2016 WHO classification, based on invasion level, it is divided into four categories. The most severe and invasive type is grade IV glioma or glioblastoma (GBM), which has a very poor prognosis and a survival rate of only 15 months. However, the molecular pathway of invasion in malignant glioma tumors has not yet been clearly el...

OBJECTIVE Tumors of the central nervous system are now thought to be the most common form of childhood malignancies. Previous studies suggested that delays might exist between symptom onset and the diagnosis of pediatric brain tumors. In the Maritime Provinces of Canada (New Brunswick, Nova Scotia, and Prince Edward Island), there are only two pediatric neurosurgical centers; therefore, the Mar...
