Biopsy of Calcifications Under Contrast Enhancement Guide (BoCCE)

Calcification clusters are 30-40% of recalls in mammographic screening, but have a low positive predictive value (\~15%) for ductal cancer in situ (DCIS) or invasive cancer. These calcifications often need histological assessment with stereotaxic guided biopsy (Mammotome). With extended calcifications, choosing the best area to biopsy may be challenging. The main objective of this 1:1 randomized controlled clinical trial is to compare the accuracy of the CESM guide (study arm with biopsy under CESM guidance) with the traditional Mammotome (control arm with biopsy under stereotactic guidance) in conducting the biopsy in the area of greatest malignancy/grade of the lesion, using as gold-standard the histological exam of the operating piece. Women recalled with indication to perform stereotactic biopsy for clusters of suspicious calcifications on mammography (BIRADS R3 or R4 or R5) not mass-associated will be included. Anticipated sample size is 100 women per arm.
