Brief summary
Breast MRI is performed in prone position which causes a number of questions. Indeed, the correlation with mammography and echography and the identification of preoperative lesions can be complex as echography and surgery are carried in supine position while mammography is performed in standing position. Moreover, the prone position is often considered as uncomfortable by the patients. However, there is few publications in the literature on breast MRI in decubitus position.
Interventions
PROCEDUREPosition for the 3.0 Tesla in Magnetic Resonance Imaging
Eligible patients will have a standard MRI in prone position. At the end of this examination, all patients will have an other standard MRI in supine position. This examination is then extended by 10 minutes without additional injection of contrast medium

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of lesions where the topography is discordant between the positions (prone and supine). | 1 day | The topography is considered discordant if the location of the lesion is different between prone and supine positions (location will be described as the positions on a clock) and / or the distance from the nipple to the lesion is greater than 2cm between prone and supine positions. |
Secondary
| Measure | Time frame |
|---|---|
| distance from lesion to pectoralis major muscle in supine position compared to the prone position | 1 day |
| Quandrant of the lesions and positions on a clock in supine position compared to the prone position | 1 day |
| Comfort patient in supine position compared to the prone position using a self-administered questionnaire | 1 day |
| distance from the anterior border of the lesion to the nipple in supine position compared to the prone position | 1 day |
| distance from cutaneous projection of the lesion to the nipple in supine position compared to the prone position | 1 day |
