50) for the majority of individual cases (128/131) and for the majority of selected regions of Results: The t-map and z-map calculated with SPMGrid and BRASS, respectively, showed a good correlation Three independentĮxpert readers blindly assigned a diagnosis based on the two map sets. Tested by correlating the quantitative parameters (z- and t-values), calculated by the two software tools,Īnd by measuring the topographical overlap of the abnormal regions (Dice score). MCI and elderly healthy controls from the EADC PET dataset.

Methods: SPMGrid and BRASS (Hermes Medical Solutions, Stockholm, Sweden) were tested on 131 To evaluate the impact of the analysis method on FDG-PET diagnostic performance.

We compared the accuracy of twoĬlinically validated tools for their ability to identify those MCI subjects progressing to AD at followup, Typical of Alzheimer’s Disease (AD) on FDG-PET brain scans. Objective: Automated voxel-based analysis methods are used to detect cortical hypometabolism
