I. Introduction
In modem health care, the integration of multi-center and multi modal medical image data into comprehensive archives is an important issue for indexing an ever increasing amount of information and represents the foundation for fostering medical collaboration. Systems for collecting and integrating multi-source and multivariate data are already known in the literature such as the Cardiac Atlas Project system [1]. In the field of neuroimaging, examples also exist witnessing the importance of data sharing, such as the INDI Project collecting resting state functional Magnetic Resonance (MR) images [2], the ADNI Project addressing the Alzheimer disease [3], or the Function BIRN investigating the causes of schizophrenia [4]. All those systems envision a network of clinical sites that share images and clinical data fed by multiple repositories and datasets. They leverage systems already available, such as the LONI Image Data Archive (IDA) [5] or the eXtensible Neuroimaging Archive Toolkit (XNAT) [6] which facilitate the data storage, management and sharing. In this perspective the work illustrated in the paper represents the first Italian infrastructure for collecting, sharing and processing MR images and associated clinical data. The aim is to create an archive with information about pediatric subjects including both healthy ones and others affected by rare diseases.
