Aim: Ultrasonography for the evaluation of hyperechoic breast lesions. Material and methods: The retrospective clinical study was conducted, after ethical permission from the institution. An ultrasonographically guided core needle biopsy was performed on 980 of 1000 subjects, with 51 percent (n=510) of lesions being benign, 41 percent (n=410) being malignant, and 8 percent (n=80) being high risk. A single radiologist with expertise in the field performed the ultrasonographically guided core needle biopsy, ultrasonographic imaging, and associated interpretation. Two orthogonal views were captured for documentation. Clinical and mammography parameters and clinical aspects, as well as additional radiologic imaging reports, were evaluated for all research individuals
