Brain Scans

The AIVO database is a retrospective “pseudo-biobank” type collection of brain scans acquired at the Turku University Hospital and Turku PET Centre. This project is conducted in the context of register study, and the image data are linked with a variety of medical and socioeconomic registers.

Because the image data have to be identified and processed retrospectively, the database is constantly updated. Below is a summary of the images we have in the database so far, grouped by higher-order systems under scrutiny. The Available scans column indicates the total number of scans theoretically available for each ligand. The Processed scans column indicates the number of scans that have been evaluated as adequate for inclusion in the database, and that has subsequently been processed with the MAGIA pipeline.
