The main objective of the research is to compare by two blind evaluators new MRI techniques with routinely used sequences.
"The main evaluation criterion will be the choice of the two (or three) evaluators as to the best sequence between the new sequence and the standard sequence. The decision criterion for considering a new sequence as superior to the standard sequence will be based on two measures: 1. The proportion of patients for whom the new sequence was preferred, which must be greater than or equal to 75%; 2. Inter-observer agreement (Cohen's Kappa coefficient), which must be greater than or equal to 0.8; When these two criteria are met, the new sequence will be considered superior to the standard sequence"
