[Stereotactic vacuum core biopsy of clustered microcalcifications classified as B1-RADS 3].

Purpose: Evaluation of stereotactic vacuum core biopsy of clustered microcalcifications categorized as BI-RADS 3.

Material And Methods: 86 patients with microcalcifications BI-RADS 3 (probably benign, < 3% malignant) underwent a stereotactic vacuum core biopsy (Mammotome, Fa. Ethicon Endo-Surgery Breast Care) using a digital stereotactic unit (Mammotest, Fa.

[Full-field digital mammography: dose-dependent detectability of breast lesions and microcalcinosis].

Objectives: The study compares contrast-detail and microcalcification detectability of a full-field digital mammography (FFDM) to a state-of-the-art conventional screen-film mammography (SFM) by using different doses in the digital system.

Materials And Methods: The investigations were performed with an FFDM (Senographe 2000 D, GEMS) and an SFM system (Senographe DMR, GEMS) using a contrast-detail mammography phantom (CDMAM) and an anthropomorphic breast phantom with superimposed microcalcifications. The digital detector was exposed with standard dose of SFM and with a dose reduction of up to 75%.
