Explanation: The "Intended Use / Indications for Use" section explicitly states "Genius AI Detection is a computer-aided detection and diagnosis (CADe/CADx) software device". The "diagnosis" component directly indicates its function as a diagnostic device.
Yes
The device description explicitly states "Genius Al Detection is a software device intended to identify potential abnormalities in breast tomosynthesis images." and details its function as analyzing images and producing CAD results, which are then packaged into a DICOM object for display on review workstations. There is no mention of accompanying hardware components.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze biological samples: In Vitro Diagnostics are designed to examine specimens taken from the human body, such as blood, urine, tissue, etc., to provide information about a person's health.
- This device analyzes medical images: The Genius AI Detection software analyzes digital breast tomosynthesis images, which are medical images, not biological samples.
- The intended use is image interpretation aid: The intended use clearly states that the device is a computer-aided detection and diagnosis (CADe/CADx) software intended to aid in the interpretation of digital breast tomosynthesis exams. This is a function related to medical imaging analysis, not in vitro testing.
Therefore, based on the definition and intended use, this device falls under the category of medical imaging software, not an In Vitro Diagnostic.
No
The provided text does not contain any explicit statement that the FDA has reviewed and approved or cleared a Predetermined Change Control Plan (PCCP) for this specific device.

Device Description
Genius AI Detection is a software device intended to identify potential abnormalities in breast tomosynthesis images. Genius AI Detection analyzes each standard mammographic view in a digital breast tomosynthesis examination using deep learning networks. For each detected lesion, Genius AI Detection produces CAD results that include the location of the lesion, an outline of the lesion and a confidence score for that lesion. Genius AI Detection also produces a case score for the entire tomosynthesis exam.
Genius AI Detection packages all CAD findings derived from the corresponding analysis of a tomosynthesis exam into a DICOM Mammography CAD SR object and distributes it for display on DICOM compliant review workstations. The interpreting physician will have access to the CAD findings concurrently to the reading of the tomosynthesis exam. In addition, a combination of peripheral information such as number of marks and case scores may be used on the review workstation to enhance the interpreting physician's workflow by offering a better organization of the patient worklist.

Summary of Performance Studies
The study was successfully executed with all 17 readers; the results below represent a per-protocol analysis of the 390 cases (106 cancers, and 284 negative cases) included in the MRMC where both rounds of reading were completed.
Based on analyses that do not control type I error and therefore cannot be generalized to specific comparisons outside this particular study, in this study:
- The average observed AUC was 0.825 (95% Cl: 0.783, 0.867) with CAD and 0.794 (95% Cl: 0.748, 0.840) without CAD. The difference in observed AUC was +0.031 (95% Cl: 0.012, 0.051).
- The average observed reader sensitivity for cancer cases was 75.9% with CAD and 66.8% without CAD. The difference in observed sensitivity was +9.0% (99% Cl: 6.0%, 12.1%).
- The average observed recall rate for non-cancer cases was 25.8% with CAD and 23.4% without CAD. The observed difference in negative recall rate was +2.4% (99% Cl: 0.7%, 4.2%).
- The average observed case read-time was 52.0s with CAD and 46.3s without CAD. The observed difference in read-time was 5.7s (95% Cl: 4.9s to 6.4s).
Hologic conducted an MRMC reader study to assess the safety and efficacy of Genius AI Detection on Hologic's high resolution tomosynthesis images, where 3D data sets are reconstructed at 70μm. Parallel to the MRMC study, a standalone study was conducted to establish equivalence of Genius AI Detection performance on Hologic's standard resolution tomosynthesis images, where 3D data sets are reconstructed at ~100um compared to the performance on the high resolution tomosynthesis images. The standalone study was conducted on paired high resolution and standard resolution 3D data sets, where each high-resolution reconstructed 3D volume had a counterpart standard resolution 3D volume, both acquired from a single exposure and under the same compression.
All the results of the standalone study confirmed that Genius AI Detection when operating under the Hologic's standard tomosynthesis acquisition mode performs comparably to when operating under the high-resolution mode.
Using an overall data set of 764 cases including 106 cancers and 658 non-cancer cases, Genius AI Detection demonstrated comparable detection performance on both Hologic's standard and high-resolution acquisition modes as observed by fROC analysis.
No significant differences were observed in the number and type of cancers detected by Genius AI Detection in either acquisition mode.
Stratified fROC analysis using lesion type as well as breast density also showed comparable performance of Genius AI Detection operating in either acquisition mode.

- The average observed reader sensitivity for cancer cases was 75.9% with CAD and 66.8% without CAD. The difference in observed sensitivity was +9.0% (99% Cl: 6.0%, 12.1%).
- . The average observed recall rate for non-cancer cases was 25.8% with CAD and 23.4% without CAD. The observed difference in negative recall rate was +2.4% (99% Cl: 0.7%, 4.2%).
- . The average observed case read-time was 52.0s with CAD and 46.3s without CAD. The observed difference in read-time was 5.7s (95% Cl: 4.9s to 6.4s).
Standalone Testing:
Hologic conducted an MRMC reader study to assess the safety and efficacy of Genius Al Detection on Hologic's high resolution tomosynthesis images, where 3D data sets are reconstructed at 70μm. Parallel to the MRMC study, a standalone study was conducted to establish equivalence of Genius Al Detection performance on Hologic's standard resolution tomosynthesis images, where 3D data sets are reconstructed at ~100um compared to the performance on the high resolution tomosynthesis images. The standalone study was conducted on paired high resolution and standard resolution 3D data sets, where each high-resolution reconstructed 3D volume had a counterpart standard resolution 3D volume, both acquired from a single exposure and under the same compression.
All the results of the standalone study confirmed that Genius Al Detection when operating under the Hologic's standard tomosynthesis acquisition mode performs comparably to when operating under the high-resolution mode.
Using an overall data set of 764 cases including 106 cancers and 658 non-cancer cases, Genius AI 1. Detection demonstrated comparable detection performance on both Hologic's standard and highresolution acquisition modes as observed by fROC analysis.
No significant differences were observed in the number and type of cancers detected by Genius Al 2. Detection in either acquisition mode.
- Stratified fROC analysis using lesion type as well as breast density also showed comparable performance of Genius Al Detection operating in either acquisition mode
Assessment of Benefit-Risk, Safety and Effectiveness, and Substantial Equivalence:
As a part of the submission, we have demonstrated the probable benefits of the device through clinical study including reader accuracy as assessed by AUC (i.e. diagnostic performance and improved assistedread detection from the sensitivity analysis. In totality, Hologic finds that the proposed device has a positive balance in terms of probable benefits vs probable risks and thus may be considered safe and effective based on the special controls established in DEN180005 such that "the device will provide improved assisted-read detection and diagnostic performance."
Conclusion:
Based on the information submitted in this premarket notification, the Genius Al Detection device and its predicate device, PowerLook® Tomo Detection V2 both have a similar intended use and are devices which aid in the detection, localization, and characterization of disease specific findings on acquired medical images. The differences discussed are not significant to the technology and clinical application of the device. The proposed Genius Al Detection device has been found to be substantially equivalent to the predicate PowerLook® Tomo Detection V2 device (K182373).
