Abstract

Magnetic Resonance Imaging (MRI) has been widely applied to various medical procedures. The daily growth of medical data leads to human mistakes in manual analysis; and increases the need for automatic analysis.  Therefore, applying tools to collect, classify, and analyse medical data automatically is essential. Medical imaging issues are extremely complex, due to the high importance of correct diagnosis and treatment of diseases in healthcare systems. For these reasons, automatic medical image analysis algorithms are used to help increase the reliability and accurate understanding of medical images. The objective of this paper is to investigate the use of Artificial Neural Network (ANN) algorithms, such as multilayer perceptron (MLP), Jordan/Eleman network, Self-Organizing Feature Map (SOFM) and Support Vector Machine (SVM), to early detect bladder cancer (diagnosis), to determine tumour staging (for the sake of prognosis), and to assess the accuracy of MRI in T staging bladder cancer. A set of functional images, taken by Magnetic Resonance (MR), was used. It was found that multilayer perceptron (MLP) neural network gave better results than all other algorithms. We developed a model that defines cancer level in order to enhance its treatment. Experimental results show that the devised approach increases the accuracy of bladder cancer diagnosis to 81.8% using Generalized Feed Forward (GFF) after processing for more than 40 hours.
