Intended Use
The MicroDose SI (model L50) is indicated for generating mammographic images that can be used for screening and diagnosis of breast cancer. The MicroDose SI (model L50) is intended to be used in the same clinical applications as traditional film/screen systems.
Device Description
This application is to add functionality to the previously cleared MicroDose SI, Model L50, (K123995) that allows for breast density measurements. The L50 submission described that the detector electronics have been modified to do spectral imaging through the functionality to discriminate between high and low energy photons based on an energy threshold. The first application of this technology is Spectral Breast Density Measurement where breast glandularity and thickness is measured simultaneously by the spectral difference in X-ray attenuation between adipose and fibroglandular tissue. The MicroDose'Sl can thereby measure volumetric glandularity and breast thickness for each pixel in the image. Total breast volume is calculated by integrating the breast thickness over the breast region. taking pixel size and beam geometry into account. Fibroglandular thickness is calculated as the product of breast thickness and volumetric glandularity for each pixel. Total fibroglandular volume is then calculated by integrating the fibroglandular thickness over the breast region. The total breast volumetric glandularity is then given as the ratio of fibroglandular to breast volume.

More Information

No
The description focuses on spectral imaging and calculations based on X-ray attenuation properties of different tissues, not on learning from data or using AI/ML algorithms for image analysis or density assessment. The performance studies evaluate the correlation of the device's measurements with existing methods and expected biological trends, not the performance of an AI/ML model.

No
The device is indicated for generating mammographic images for screening and diagnosis of breast cancer, and for measuring breast density. It does not provide any form of therapy.

Yes

The device is indicated for generating mammographic images for screening and diagnosis of breast cancer and measures breast density, which are diagnostic purposes.

No

The device description explicitly states that this application is an addition of functionality to a previously cleared hardware device, the MicroDose SI, Model L50. It describes modifications to the detector electronics and the use of spectral imaging technology, which are hardware-based functionalities.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
  • Device Function: The MicroDose SI (model L50) is a medical imaging device that generates mammographic images and performs breast density measurements based on the spectral properties of X-rays passing through the breast tissue. It analyzes the physical properties of the breast in vivo (within the living body) using imaging technology.
  • Lack of Specimen Analysis: The device does not analyze biological specimens (like blood, tissue samples, etc.) collected from the patient.

Therefore, based on the provided information, the MicroDose SI (model L50) is a medical imaging device, not an In Vitro Diagnostic.

The verification and validation activities confirm that the established acceptance criteria were met.

G. CONCLUSION

The breast density measurement functionality that is the subject of this application relies on the technology of a FFDM device which has already been cleared by the FDA (MicroDose SI, K123995). Breast density assessments have previously been introduced by Quantra (K120472) and Volpara (K102556). These devices provide information that is very similar to that generated by the MicroDose SI (Model L50), and are intended for the same purpose, i.e. to generate adjunctive information regarding breast density. Like the breast density functionality of the predicate devices Volpara and Quantra, the MicroDose Breast Density Measurement aids the clinician in the assessment of breast tissue composition. The Breast Density Measurement functionality is well characterized by the design control process and the physical laboratory tests show results that are comparative to the predicate devices.

Dear Mr. Lins:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
