C omputer method development for early diagnosis of Alzheimer’s disease (AD) is one of the helpful ways in its prevention.
Computer aided diagnosis system (CADS) based on magnetic resonance (MR) image processing can improve medical
analysis and interpretation. Mental status in AD can be recognized by related biomarkers such as involvement of white matter
(WM) and gray matter (GM) atrophy. WM volume in AD changes more than controls and it can show the reduction of GM
also. An automatic system to measure WM atrophy from MR images can support the neuropsychological tests and be helpful
in treatment. We developed a CADS that allows segmentation of WM by a novel method in a reliable way to extract the features
of the extracted volume. We assume that all datasets were analyzed including a preprocessing. The method consists of a series
of morphological operations on the binary images to extract WM volume, feature extraction from images using single level
discrete wavelet transform, feature reduction using principle component analysis (PCA). The extracted features are used to
identify the characteristics of segmented WM. This system has the possibility to classify these features with a support vector
machine (SVM). This classification is helpful to categorize specifications of WM in different types of AD. This method was
applied to a reference public dataset (OASIS). The accuracy of our system to extract WM was 85%. Therefore, with this system,
WM volume segmentation, assessment of its features and classifying them were feasible and trustable in MR images of AD.
This result is a marked improvement on the state-of-the-art in the prognostic precision of AD.
