Technical Questions

CAD stands for Computed Assisted Detection. As such, traditional CAD used for breast cancer screening are designed to detect suspicious findings. However, they can’t discriminate between benign and malignant patterns. Using machine learning, a subset of artificial intelligence (train a machine to learn from data) and the most advanced data science techniques (reproduce human intelligence from radiologists), MammoScreen® can detect and also characterize the level of suspicion of findings. Consequently, MammoScreen® can display only the suspicious findings on the interface and don’t overwhelm the work space with benign findings. MammoScreen® provides actionable information to support your interpretation of the exam by giving you a level of suspicion at the mammogram, breast and lesion levels.

In the US, MammoScreen® is intended for use as a concurrent reading aid for interpreting physicians, to help identify findings on screening FFDM acquired with compatible mammography systems and assess their level of suspicion. Output of the device includes marks placed on findings on the mammogram and level of suspicion scores. The findings could be soft tissue lesions or calcifications. The level of suspicion score is expressed at the finding level, for each breast and overall for the mammogram. Patient management decisions should not be made solely on the basis of analysis by MammoScreen®.

MammoScreen® is intended to be used with screening FFDM acquired with compatible mammography systems.

One should not use MammoScreen® information (even if a report is generated on the interface) to guide clinical decision for:

  • poor quality images (e.g. blurry images, bad acquisition, etc.)
  • non-standard mammographic views (e.g. projections, magnifications, compressions, etc.)
  • synthetic 2D images
  • women with previous breast surgery or breast implants or internal breast markers
  • women with a pacemaker

Remember that MammoScreen® only uses the mammogram, and no additional information available to the interpreting physician. As a consequence, some detected findings may not be relevant for the user (False Positive). Some soft tissue lesions or calcifications may also be missed or undervalued (False Negative).

MammoScreen’s users should refer to the User Manual for a complete list of indications of use.

MammoScreen® detects all the potential cancer lesions and displays differently t2 subgroups:

  • Soft tissue lesions including mass, asymmetries, distortions, and lymph nodes
  • Cluster of calcifications

The soft tissue lesions are represented by a circle and the calcifications are represented by a triangle.


Integration in your practice

Processing time is very quick and mostly depends on your network speed to send the mammogram to our cloud and receive the report. Usually it takes less than 2 minutes overall and is used in centers where mammograms are interpreted immediately after acquisition.

MammoScreen® has not been designed to be integrated into your mammography reader. Placed on a separate screen, it enables each radiologist to look at the AI information when he/she needs it during the interpretation process. If the display as an overlay in your viewer is a prerequisite for you, please contact us via our contact form by clicking here to discuss feasibility.

Yes. Depending on your IT infrastructure, we can easily deploy at one or multiple sites. Please contact us to together define the best IT strategy. Please send us a message via our contact form by clicking here and the right person will come back to you.

We are HIPAA compliant and we are a HIPAA compliant cloud host to ensure maximal protection. Moreover we systematically de-identify every DICOM image leaving your practice and systematically delete images from our cloud as soon as the output report has been successfully received (a few minutes). If you have any questions, don’t hesitate to ask our Data Protection Officer (DPO) directly by sending an email to “dpo @ therapixel.com”


Underlying AI technology & Clinical validation

MammoScreen® is a concurrent read software and as such had to demonstrate an increase of performances of radiologists when using the software while interpreting cases in order to receive FDA clearance. Standalone performances can’t be directly translated into an increase of performance of radiologists.

In a Multi-Reader, Multi-Case study, we have shown that MammoScreen® improves radiologists cancer detection rate by 5 percentage points while lowering their false positive rate by 6 percentage points. The paper of this study was published in Radiology: Artificial Intelligence.

Our database is made  of over 1 million screening mammograms coming from 15 sites both in the EU and the USA, and from both private and public health institutions. The diversity of sources ensures a fair representation of populations of all origins living in these countries (Caucasian, African American, Hispanic, etc.). It is also largely enriched with cancers to cover a multitude of different lesion types (invasive, in situ, masse, calcification, asymmetry, distortion). Among these cases, there is a natural distribution of density type for these  population.

We have tested our algorithms on 2 different data sets never used by the algorithm for training (one US, one EU). This dataset of screening mammograms is composed of 1,700 cancers (positive biopsy within 3 months of the screening exam) and 20,000 true negatives (confirmed negative on the next screening, no cancer found in the life of the woman). Note that only one exam per patient was used.


Patients FAQs

Artificial Intelligence is the ability of a computer to do tasks that are usually done by humans by mimicking  human intelligence and judgement. Although there are no AIs that can perform the wide variety of tasks an ordinary human can do, some AIs can match humans in specific tasks.

The AI is initially trained by being presented with many thousands of confirmed cases of cancer and normal exams, from which the algorithm learns to recognize areas of concern on the image. The AI is then validated on very large numbers of exams it has never seen to verify it has learned properly. Then, when your mammogram is processed by the AI it can detect and characterize suspicious areas for the radiologist to check.

Yes, a radiologist will continue to read your mammogram. AI software assists the radiologist by giving them a second set of eyes on your mammogram. This assures you that your radiologist has all the latest advanced tools to provide an accurate diagnosis.

Please check with your provider. Different insurance groups cover different things so please check with your insurance provider to see if this is covered. A basic cost is covered under the screening mammogram coding; however, some facilities may add an additional charge that may or may not be covered by your insurance provider.

AI works with your radiologist when reading the mammogram. It requires that you still have your routine screening mammogram performed. This is a software solution that helps your radiologists read the exam with more accuracy.

Automated breast density assessment is a type of AI that gives a specific breast density value, an important risk factor to consider. MammoScreen® provides an overall assessment on your mammogram and analyzes all aspects of the mammogram including breast density. It does not give a breast density assessment value but provides a level of the suspicion for the lesions it finds.

No, this is strictly a computer software solution  that analyzes your mammograms, after the images have been taken.

Mammography is the best tool to screen for breast cancer in the general population. However, mammography alone can still miss cancer.  Physicians are human and due to human error, some cancers could be missed. MammoScreen® is a tool that assists the radiologist in finding cancers that can sometimes be missed.

MammoScreen® works with your radiologist when reading your mammogram to find small subtle suspicious lesions.  Some cancers can look like a snowflake in a snowstorm so this is a tool that helps the radiologist see the smallest or the most difficult cancers to catch. Suspicious lesions will have to be biopsied to confirm if this is cancer or not (about one in ten biopsies come back positive for cancer).

As a human would, AI learns by seeing data. AI can see and learn from hundreds of thousands of mammographic images in a few hours, something that a human could not do. AI learns from many more cases than a radiologist would see in their entire career.

Newer cars are built to incorporate AI. The most common use case for this particular question is that it is a software  capable of autonomous movement. In order to be autonomous, it must be able to make decisions of its own. AI is the technology behind driverless cars that are being tested at this very moment.

Not all cell phones have AI; however, more and more mobile phones incorporate processors with AI  capacity. This technology allows your cell phone to choose how to manage its resources to achieve greater speed, reduce energy consumption, track your workouts, etc.

MammoScreen® AI  software has deep learning capacity meaning that it is trained to look for non typical discrepancies such as cancer on your mammogram by analyzing thousands of mammograms. Medical imaging AI uses a different category of AI algorithms than a car or a smartphone, but more importantly is rigorously checked and independently examined by the FDA before being used on patients.

No, AI is strictly regulated and medically tested. In addition, the radiologists will remain the sole decision maker. AI is used strictly as an additional tool to assist them in reading your mammogram.

AI is a new technology so many facilities do not have this technology yet. If you are interested in finding out more, call your facility and ask if they do have AI for screening mammography.
