These show up on conventional MRI scans, but it is often difficult to identify the exact type of the pathology from the grayscale image. We employ the use of Support Vector Machines (SVM) to work on the MR Spectroscopy [6, 12] data and correctly identify the condition-especially in seemingly vague cases where radiologists cannot rule out high uncertainty in their conclusion. The SVM trains on data sets collected for different patients and optimizes its hyperplanes based on eight input variables – T2, CHO, ADC, CR, CHO/NAA, CR/NAA, LIP/LAC, MI, CH/CR, T2 periphery [6] and Refractive index. Refractive index is an additional parameter which we include to get better boundary lines and accuracy, as shown in our prior works [10]. We test this SVM on a set of 19 patients’ data and achieve 100% accuracy in predictions. The training and testing is carried out in MATLAB.</p>}, number={3}, journal={British Journal of Healthcare and Medical Research}, author={Jain, Sparsh and Biswas, Tapan Krishna and Bandyopadhyay, Rajib}, year={2018}, month={Jul.}, pages={19} }
