Machine learning-based Alzheimer’s disease Designation (MAD)

This SPM extension evaluates whether the given brain FDG PET images “look like” an Alzheimer’s disease (AD) patient’s or not (non-AD).

The brain FDG PET images must be already pre-processed (normalized and smoothed with [8 8 8]mm Gaussian filter) using SPM12 (with “old normalize” routine on to a PET template). Please note that the original study was conducted without structural MRI co-registration.

The program computes subject scores and labels (AD vs. non-AD) estimated by 5 different algorithms described in [1].

1. General Linear Model

2. Scaled Subprofile Modeling - single principal component

3. Scaled Subprofile Modeling - linearly regressed principal components

4. Support Vector Machine – Iterative Single Data Algorithm

5. Support Vector Machine – Sequential Minimal Optimization

The package contains MAT file (~1GB). Please contact us for further instructions on how to download the software package.

Requirement: SPM12 must be installed running on MATLAB (with statistics toolbox).
