BACKGROUND: The main reason for the development and implementation of artificial intelligence (AI) technologies in neuro-oncology is high prevalence brain tumors reaching up to 200 cases per 100,000 population. incidence a primary focus 5%10%; however, 60%70% those who die from malignant neoplasms have metastases brain. Magnetic resonance imaging (MRI) most common method non-invasive diagnosis ...

In the last few years, a very huge development has occurred in medical techniques using artificial intelligence tools, especially diagnosis field. One of essential things is brain tumor (BT) detection and diagnosis. This kind disease needs an expert physician to decide on treatment or surgical operation based magnetic resonance imaging (MRI) images; therefore, researchers focus such images anal...

Brain tumors are deadly but become deadliest because of delayed and inefficient diagnosis process. Large variations in tumor types also instigate additional complexity. Machine vision brain addresses the problem. This research’s objective was to develop a classification model based on machine techniques using Magnetic Resonance Imaging (MRI). For this purpose, novel hybrid-brain-tumor-classific...
