Multi-Reader, Multi-Case, Cross-Over, Retrospective Study to Evaluate Effectiveness of Lunit INSIGHT DBT

This study aims to evaluate Effectiveness of Lunit INSIGHT DBT in the assistance of detection and diagnosis of breast cancer during 3D mammography interpretation

Inclusion Criteria:[For All Subject Groups]Female22 years old or older[For 'Control (Non-cancer)' Group]Negative Cases Interpreted as BI-RADS 0 (Assessment Incomplete) or BI-RADS 1 (Negative) with no cancers on the DBT exam and confirmed as BI-RADS 1 (Negative) on the further diagnostic imaging (e.g., MMG, DBT, MRI, CT and Ultrasound) taken at least after 1 year of the DBT exam.Benign Cases Interpreted as BI-RADS 0 (Assessment Incomplete) or BI-RADS 2 (Benign) with a visible lesion on the DBT exam and confirmed as BI-RADS 2 (Benign) on the further diagnostic imaging (e.g., MMG, DBT, MRI, CT and Ultrasound) taken at least after 1 year of the DBT exam without a further breast biopsy.Or for the biopsy-proven benign exams, interpreted as BI-RADS 0 (Assessment Incomplete), BI-RADS 3 (Probably Benign), 4 (Suspicious) or 5 (Highly Suggestive of Malignancy) with a visible suspicious lesion for breast cancer on the DBT exam but confirmed as benign through subsequent biopsy conducted within following 1 year of the DBT exam.[For 'Condition (Cancer)' Group] Interpreted as BI-RADS 0 (Assessment Incomplete), BI-RADS 3 (Probably Benign), 4 (Suspicious) or 5 (Highly Suggestive of Malignancy) with a visible suspicious lesion for breast cancer on the DBT exam and confirmed as a cancer (malignant) through the subsequent biopsy conducted within following 1 year of the DBT exam.Exclusion Criteria:Previous breast cancerPrevious vacuum-assisted biopsy, surgical biopsy or surgery in breastPresence of a breast implant or pacemaker on the required images: 4 views (RCC, RMLO, LCC, LMLO) images of Screening or diagnostic DBT exams with a FFDM (Full-Field Digital mammography) image or with a synthetic 2D image
