Prostate cancer (PCa) is the second most frequently
diagnosed cancer and the sixth leading cause of cancer
death among men worldwide [1]. Several studies [2-4]
have proven that the diagnostic accuracy of PCa
detection can be significantly improved by combining
different MR sequences, and several computer-aided
diagnosis (CAD) systems have been proposed to integrate
the MR information. However, no comparison has been made
to find out which system performs better. In this study,
we evaluate the performance of four widely used
classifiers using leave-one-out (LOO) method. MLP and
SVM classifiers which have been successfully applied in
many branches of medical diagnostics seem promising
here. Because of their abilities to resolve nonlinear
complex relations among input variables, without the
need for any prior assumptions about these relations,
MLP and SVM models are more advisable for PCa detection.
