Brain magnetic resonance images (MRI) is crucial in modern medical diagnoses. However, there is usually a time delay between images acquisition and interpretation of radiologists and/or doctors who prescribe the images, which may contribute to clinical exacerbation of the patients. In this preliminary study, we use symmetry index to discriminate between normal brain structures and intracranial pathologies, and to provide a foundation for images auto-alarm system in the future. Experimental results of the proposed algorithm on 24 MR images (11 pathological, 13 healthy), show that the symmetric index can help differentiate the normal and abnormal brain structures with promising performance.
