Biomedical images are the core of medical science. Magnetic Resonance Imaging (MRI) Clear images of the human brain's internal structure or of other parts of the body are provided by scans. Segmentation of brain tumors by MRI data is a rather important task, but it is done manually by medical experts which is very cumbersome and time-consuming. Several methods for the automated identification of brain tumor and brain segmentation have been suggested for MRI images. The goal is the separation by brain tumor from normal brain tissue White Matter (WM), Gray Matter (GM) or brain spinal fluid (CSF), in the different tube tissues such as active cells, the necrotic core as well as edema. Because of non-invasive visualization and the strong comparison of soft tissues in MRI images, MRI-based brain tumor segmentation work has drawn more interest in recent years. As the brain tumor section is built over nearly 20 years, novel methods using computer-aided techniques are maturing and closer to standard clinical applications. The purpose of this paper is to provide an overview of MRI segmentation approaches for brain tumors. To begin with, a short introduction to brain tumors and imaging methods of brain tumors is given. Then pre-processing techniques or state-of-the-art MRI segmentation methods are applied.
