Distinguishing Parkinson's disease from atypical parkinsonian syndromes using PET data and a computer system based on support vector machines and Bayesian networks Segovia Román, Fermín Álvarez Illán, Ignacio Gorriz Sáez, Juan Manuel Ramírez Pérez De Inestrosa, Javier Rominger, Axel Levin, Johannes Bayesian network Support vector machine 18F-DMFP PET Parkinson's disease Multivariate analysis Differentiating between Parkinson's disease (PD) and atypical parkinsonian syndromes (APS) is still a challenge, specially at early stages when the patients show similar symptoms. During last years, several computer systems have been proposed in order to improve the diagnosis of PD, but their accuracy is still limited. In this work we demonstrate a full automatic computer system to assist the diagnosis of PD using 18F-DMFP PET data. First, a few regions of interest are selected by means of a two-sample t-test. The accuracy of the selected regions to separate PD from APS patients is then computed using a support vector machine classifier. The accuracy values are finally used to train a Bayesian network that can be used to predict the class of new unseen data. This methodology was evaluated using a database with 87 neuroimages, achieving accuracy rates over 78%. A fair comparison with other similar approaches is also provided. 2015-12-10T13:23:50Z 2015-12-10T13:23:50Z 2015 info:eu-repo/semantics/article Segovia, F.; et al.
