Abstract

The purpose of the paper is to research the influence of quality control (QC) on image retrieval applied to longitudinal images for Alzheimer’s Disease. In fact, structural Magnetic Resonance Images (MRI) used in Alzheimer’s Disease studies usually undergo the fully automated image processing pipelines. This process is prone to errors that can bias the results of the subsequent examination. The main goal of the paper is investigated whether the quality control of the automatically processed images can impact the retrieval performance. The research includes all subjects from the ADNI database with MRI scans available for four consecutive time points, scans at baseline, and 6, 12, and 24 months later. Hence, 267 in total are selected. All scans are processed using Freesurfer’s longitudinal stream. Measurements of cortical and subcortical brain structures such as volumes and cortical thickness of the brain regions were estimated and used as features. The retrieval results were evaluated with and without QC. According to the results, the QC phase significantly improves the retrieval. As a result, it can be concluded that QC influences the overall retrieval performance and is extremely important in this context.
