Brief Summary

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

Detailed Description

The primary objective of the trial is to evaluate the effectiveness of Lunit INSIGHT DBT in the assistance of detection and diagnosis of breast cancer by comparing the clinical performance of radiologists before and after using Lunit INSIGHT DBT in their DBT reading and secondarily examining the use of Lunit INSIGHT DBT to shorten DBT reading time.

Conditions

Breast Cancer

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: RETROSPECTIVE

Study Groups

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.

Digital Breast Tomosynthesis

Intervention Type: RADIATION

Digital Breast Tomosynthesis (DBT) is a type of 3D mammography that creates detailed images of the breast tissue. It uses X-rays to take multiple images at different angles and combines them to create a clear, layered view of the breast tissue. DBT is used for breast cancer screening and diagnosis and provides a more accurate view of the breast tissue compared to traditional 2D mammography.

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.
