Background: This paper endeavors to identify an expedient approach for the detection of the brain tumor in MRI images. The detection of tumor is based on i) review of the machine learning approach for the identification of brain tumor and ii) review of a suitable approach for brain tumor detection. Discussion: This review focuses on different imaging techniques such as X-rays, PET, CT- Scan, and MRI. This survey identifies a different approach with better accuracy for tumor detection. This further includes the image processing method. In most applications, machine learning shows better performance than manual segmentation of the brain tumors from MRI images as it is a difficult and time-consuming task. For fast and better computational results, radiology used a different approach with MRI, CT-scan, X-ray, and PET. Furthermore, summarizing the literature, this paper also provides a critical evaluation of the surveyed literature which reveals new facets of research. Conclusion: The problem faced by the researchers during brain tumor detection techniques and machine learning applications for clinical settings have also been discussed.

Brain tumors have different characteristics such as shape, size, location, and image intensities. Magnetic-resonance images (MRIs) typically have a degree of noise and randomness associated with the natural random nature of brain structure. MRI is a profoundly created medical imaging strategy giving a range of data about the individual’s delicate tissue structure. Even though it gives a rich data, the complex dynamics of the tumor evolution cannot be captured perfectly because of the uncertainty in the tumor segmentations. Different methods are available to identify and segment a brain tumor. Stages of medical image processing in brain tumor detection are discussed in this paper and overview of the analogous papers is quoted by analyzing several research papers. This paper provides delving of technologies which can be used to prognosticate brain tumor.

<p class="Abstract">Even with the enormous progress in medical technology, brain tumor detection is still an extremely tedious and complex task for the physicians. The early and accurate detection of brain tumors enables effective and efficient therapy and thus can result in increased survival rates. Automatic detection and classification of brain tumors have the potential to achieve efficiency and a higher degree of predictable accuracy. However, it is well established that the accuracy performance of automatic detection and classification techniques varies from technique to technique, and tends to be image modality dependent. This paper reviews the state-of-the-art detection techniques and highlights their pros and cons.</p>
