We
have verified thanks to a specific common quality control that 7 MRI devices
included in a multicenter clinical project, had homogenous and acceptable
characteristics to allow quantification and comparison between parameters
extracted from different patient images acquired on different sites and to
permit correlation with biopsies. This quality control was established with
sequences from the MRI protocol. The studied parameters slightly varied
depending on the different sites and MRI manufacturers and were in the
awaiting of the project. This kind of quality control procedure should be
included at the early beginning of any multicenter clinical projects
involving quantitative MRI.
