Diagnostic screening. The normal eligible screening population will first undergo a mammography, then an echography screening followed by a fast MRI screening.

Diagnostic screening. The normal eligible screening population will first undergo a mammography, then an echography screening followed by a fast MRI screening.

Two views (craniocaudal and mediolateral oblique) will be obtained of each breast with digital mammography by using a commercially available system. The reader will first interpret the digital mammography using a dedicated workstation.The radiologist will rate the images from each examination by using a standardized ACR five-point rating scale. Furthermore, if a reader records a positive score (>2), mammographic features have to be specified (localization, number of ACR>2 lesions,using predefined evaluation form). Scores are recorded directly into the PACS database and locked after each reading session.

After the digital mammography, the same reader will perform Ultrasound of both breasts using the transmitter of 10-13 MHertz (Acuson Antares (Siemens)). The reader will then interpret the ultrasound images using the same methodology as for digital mammography, described above (ACR five point rating scale).

The same day, the Ultra FAST Breast Magnetic Resonance will be performed on 3T unit with 8 channel dedicated breast coil. Sequences: 3 Dimensional Gradient echo with Fat Saturation before and after Gadolinium injection (acquisition time 2 minutes). Initial post processing: MPR and automatic subtraction. The reader has to assess the MRI images using the same methodology as for digital mammography, according to the American College of Radiology Breast Imaging Reporting and Data System.
