Indications for Use
DenSeeMammo is a software application intended for use with digital mammography systems. DenSeeMammo estimates BI-RADS breast density value by analyzing processed digital 2D mammograms using a fully automated comparison procedure. DenSeeMammo provides a BI-RADS breast density 5th Edition category to aid radiologists in the assessment of breast density. DenSeeMammo produces adjunctive information. It is not an interpretive or diagnostic aid when the final assessment of breast density category is made by an MQSA qualified interpreting physician. DenSeeMammo core software has been built and tested on OS X based computers. DenSeeMammo graphical use interface software has been built and tested on Windows, OS X and Linux based computers. DenSeeMammo is compatible for images obtained from GE Senographe Essentials systems.
Device Story
DenSeeMammo is a software application for digital mammography; processes DICOM images from GE Senographe Essentials systems. Operates via client-server architecture on local networks; server performs computations and hosts GUI; user accesses via web browser. Uses proprietary comparison algorithms against qualified databases of images previously assessed by MQSA radiologists. Outputs BI-RADS 5th Edition breast density category per patient (based on maximum density of both breasts). Used by radiologists in clinical settings; provides adjunctive information only; not for primary interpretation or diagnosis. Benefits include standardized, automated breast density assessment to assist radiologists in clinical decision-making.
Clinical Evidence
Bench testing only. Verification included reproducibility testing (running software twice on datasets), comparison of left/right breast density, and comparison of software results against visual assessments by MQSA radiologists. Clinical validation consisted of beta site testing to assess integration into existing systems and usability for target users. All testing met established acceptance criteria.
Technological Characteristics
Software-only device; client-server architecture. Core software runs on OS X; GUI compatible with Windows, OS X, and Linux. Developed using Java 1.8; MVC architectural pattern. Compliant with IEC 62304 (software lifecycle) and ISO 14971 (risk management). Connectivity via local network; web-browser interface.
Indications for Use
Indicated for symptomatic and asymptomatic women undergoing mammography to provide BI-RADS 5th Edition breast density category estimates as an adjunctive tool for radiologists.
Regulatory Classification
Identification
A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.
Special Controls
