Intended Use
DM-Density is a software application intended for use with compatible full field digital mammography systems. DM-Density calculates percent breast density defined as the ratio of fibroglandular tissue to total breast area estimates. DM-Density provides these numerical values for each breast as well as a density category to aid interpreting physicians in the assessment of breast tissue composition. DM-Density produces adjunctive information. It is not a diagnostic aid.
Device Description
DM-Density is a standalone software application that automatically analyzes "for presentation" full field digital mammograms to calculate breast tissue composition. The software processes full field digital mammograms according to proprietary algorithms and generates a Breast Density Grade in accordance with the American College of Radiology's Breast Imaging Reporting and Data System (BI-RADS) density classification scales. DM-Density has been validated on Hologic's Selenia Dimensions and Lorad Selenia systems. DM-Density data output is packaged for viewing on a mammography workstation or PACS as a DICOM mammography Structured Report or Secondary Capture. Output may also be transmitted to a RIS.

No
The summary describes proprietary algorithms and validation against expert radiologist assessments, but there is no mention of AI, ML, deep learning, or neural networks. The performance metrics (Pearson's Correlation, Kappa) are also not typical for evaluating AI/ML models in this context.

No
The device is a software application that calculates percent breast density to aid interpreting physicians in the assessment of breast tissue composition. It provides adjunctive information and is explicitly stated as "not a diagnostic aid." It does not provide any treatment or direct therapy.

No.
The "Intended Use / Indications for Use" section explicitly states: "It is not a diagnostic aid." The device provides adjunctive information and aid in the assessment of breast tissue composition, but does not diagnose.

Yes

The device is explicitly described as a "standalone software application" that processes digital mammograms. While it interacts with mammography systems and workstations, the device itself is solely the software component.

Based on the provided information, yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use states that the software "calculates percent breast density defined as the ratio of fibroglandular tissue to total breast area estimates." This calculation is performed on data derived from the patient (the mammogram images).
  • Device Description: The device "automatically analyzes 'for presentation' full field digital mammograms to calculate breast tissue composition." Again, this analysis is performed on patient-derived data.
  • Nature of the Data: Mammogram images are a form of in vitro diagnostic data, as they are obtained from the patient's body and analyzed outside of the body to provide information about the patient's health status.
  • Purpose: While the device is described as providing "adjunctive information" and "not a diagnostic aid," the act of calculating breast density from a mammogram falls under the umbrella of in vitro diagnostics. It's providing objective measurements derived from a biological sample (the image representing the breast tissue) to aid in the assessment of a patient's condition (breast tissue composition).

Even though the software itself doesn't directly diagnose a disease, the process of analyzing the mammogram to determine breast density is an in vitro diagnostic procedure. The software is a tool used within that process.

The fact that it's a software application analyzing images doesn't preclude it from being an IVD. Many IVDs are software-based, analyzing data from various sources like imaging, genetic sequencing, or laboratory tests.

BI-RADS 4th Edition
For each breast:

  • Area of fibroglandular tissue (cm²)
  • · Area of breast (cm2)
  • Area-based breast density (%)
    For each patient: DM-Density breast density grade and percent breast density

BI-RADS 5th Edition For each patient: DM-Density breast density grade

Alternative configuration options are available to match user preferences.

DM-Density can process approximately 600 cases per hour.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-Clinical Performance Data:
Results from internal verification and validation testing performed in accordance with Densitas' design control processes confirm that DM-Density product specifications have been met. Supporting documentation is included in this 510(k) Premarket Notification and supports the claims of substantial equivalence to the predicate device.

Verification testing consisted of unit and integrated system level testing. A risk analysis in accordance with ISO 14971 was completed as part of the software design and development effort. Validation testing relied on expert radiologist visual assessments of mammography density, and is summarized as follows:

  • Reliability was assessed using the Pearson's Correlation Coefficient by comparing the DM-Density percent density, dense breast area and total area measurements for Left and Right breasts as well as for CC and MLO views.
  • Accuracy was assessed by validating DM-Density percent density and total area measurements. The . accuracy of DM-Density dense breast area measurements follows by implication.
  • . Accuracy was further assessed by validating the Breast Density Grade assessments to known Breast Density Grade assessments using the Kappa statistic.
  • Reproducibility was assessed with the Pearson Correlation Coefficient using a dataset from subjects . who had two mammograms acquired on compatible mammography acquisition systems within a two year time period.
  • • The inverse relationship between breast density and age was assessed by calculating the Pearson's Correlation Coefficient between DM-Density percent density measures and age at time of screening.

DM-Density provides these numerical values for each breast as well as a density category to aid interpreting physicians in the assessment of breast tissue composition. DM-Density produces adjunctive information. It is not a diagnostic aid.

Substantial Equivalence Discussion:

DM-Density and iReveal (formerly M-Vu Breast Density) calculate breast density as a ratio of fibroglandular tissue and total breast area estimates. Both devices are not to be used as diagnostic aids, but to provide adjunctive information only. Users in both cases must be qualified medical practitioners and exercise their professional judgment when formulating diagnostic decisions and selecting appropriate treatment paths that are supported by breast density data. Both devices are DICOM-compliant and rely on DICOM imaging data from digital mammography systems (data input).
