Detection of brain tumors in MRI images is the first step in brain cancer diagnosis.The accuracy of the diagnosis depends highly on the expertise of radiologists.Therefore,automated diagnosis of brain cancer from MRI is receiving a large amount of attention.Also,MRI tumor detection is usually ...
All MRI images are resized to a standard dimension to ensure uniformity in input size for the model. This is essential because convolutional neural networks (CNNs) require a fixed input size. Rescaling the pixel values to a range of 0 to 1 assists in stabilizing the training process as it ...

Brain cancer, also known as brain tumors, refers to a complex group of diseases that arise from abnormal cell growth in the brain. These tumors can be classified based on the type of cells they originate from, as well as their molecular features and aggressiveness. While the exact causes of...
Secondary tumors most commonly arise from the lungs or breast. Other cancers, especiallymelanoma(a type of skin cancer), renal cell cancer (a type ofkidney cancer), andlymphoma(a cancer of the immune system) can spread to the brain. When this happens, the cancer is the same as the origin...

Researchers from the School of Biomedical Engineering & Imaging Sciences (BMEIS) have published a systematic review in Neuro-Oncology Advances exploring the use of MRI imaging techniques to identify non-invasive biomarkers in brain cancer.
They employed a two-channel CNN, a low-complexity framework that increases accuracy by 98.21%, to classify between melanoma and healthy tumor MRI images. Then, a melanoma MRI dataset that had been classified from a previous phase was used to detect cancer locations using this architecture as a...
Although brain cancer rarely spreads to other organs, it can spread to other parts of your brain and central nervous system. Secondary brain tumors are malignant tumors that started in other cells of your body. They come from cancer that started somewhere and spread (metastasized) to your brain...
