We are the users of the XNAT data management system that has been established within NHS GG&C. We are very pleased with the system as it allows swift and easy access to our clinical trial and research project imaging data. We recognize that the system greatly improves the efficiency with which we can conduct our work. The system also aids our work by organising and storing imaging data in a logical and clear manner that is intuitive for users to work with. We would therefore encourage this application to be more comprehensively supported, developed and managed such as to extract the maximum possible benefit from this excellent tool.
