Breast MRI is increasingly important in breast screening imaging. It is currently based on dynamic sequences after contrast injection whose temporal resolution must be less than 90 seconds with dynamic acquisitions at different times. These curves profiles are designed to differentiate benign from malignant lesions. Recently, Mann et al, (2014) showed that increasing the temporal resolution of dynamic acquisitions; lesion enhancement curves over time were more accurate than the curves usually performed. It seems necessary to work on sequences having better temporal resolution without compromising however spatial resolution.

Eligible patient will have a standard MRI. The images taken before 4min30 and after 6min after to the injection of gadolimium contrast medium will be carried out with the standard image acquisition. The images taken between 4min30 and 6min after the injection of gadolimium contrast medium will be carried out with the compressed sensing image acquisition.

Agreement between compressed sensing and standard image acquisition
Agreement between compressed sensing and standard image acquisition is defined by percentage of lesions detected by both modes of acquisitions
