MRI acronyms : cross-vendor comparison

On the basis of data collected from the main manufacturers present on the French MRI market, we offer you a classification of the different sequences and options present in this field.

This classification is based on the fundamental and specific physical principles of MRI

Its purpose is to be a teaching aid in learning MRI thanks to the scheduling of data in the form of families. It is also used as a tool for exchange and communication between MRI professionals by highlighting equivalences from one manufacturer to another.
