A Review on Volume Calculation of Brain Abnormalities from MRI of Brain using CAD system

Brain abnormalities and the tumor segmentation using computer aided design (CAD) is a challenging task because of the high diversity in the appearance of abnormal and tumor tissues among different patients and in many cases similarity with the normal tissues. Magnetic resonance imaging (MRI) is advanced medical imaging technique from which a lot of information about human soft tissue is gathered. Using this MRI of brain volume measurement by the CAD system is more realistic for diagnosis of tumor or abnormalities. Here these volume measurement approaches are reviewed with an importance placed on enlightening the advantages and drawbacks of these methods for brain abnormality and tumor quantification.
