Secondary |
Acceptability of the examination for the patient: leackertLikert scale |
will be assessed by a Likert scale. which is a psychometric tool for measuring an attitude in individuals. It consists of one or more statements (statements or items) for which the respondent expresses her degree of agreement or disagreement (5 items from 1 to 5 points : from "very poor", "poor", "average", "good", "very good"). A scale of several items can be summarized by the average of the item scores. |
Through MRI study completion an average of 6 months |

Reproducibility of the examination analysis |
will be assessed by means of Kappa coefficient |
After study completion, an average of one year |
