Assessment of the extent of microcalcifications to predict the size of a ductal carcinoma in situ: comparison between tomosynthesis and conventional mammography.

Objectives: The objective was to determine if digital tomosynthesis of the breast (DBT) assesses the extension of ductal carcinoma in situ (DCIS) with higher precision than mammography (MG).

Material And Methods: The local ethics committee approved this retrospective study including 26 patients with DCIS, which were rated by three radiologists. Statistics were performed using intraclass correlation (ICC) for interreader agreement and the Pearson correlation for correlation of MG and DBT.
