CATI was born out of a consortium of neuroimaging research laboratories with complementary expertise : NeuroSpin (the French high-field MR imaging center of the CEA) and four teams located in La Pitié-Salpêtrière Hospital: ARAMIS and CENIR (the neuroimaging analysis research team and the neuroimaging platform of the Paris Brain Institute), IM2A (the Institute for Memory and Alzheimer’s disease) and LIB (an INSERM/Sorbonne Université unit focusing on research on functional imaging). These teams have been collaborating for several years, and in 2011, they were granted €9m by the French Alzheimer’s disease initiative to create CATI – a national platform aiming to support multicenter neuroimaging studies.
