Improving detection of Breast Cancer with compression at optimal pressure

Worldwide, over 150 million mammograms are performed every year. Recent studies demonstrate that a too low pressure leads to a higher recall rate and false positives. Too high pressure reduces detectability of breast cancer. The only way to achieve pressure guidance in a consequent way during mammographic positioning is by using the Sensitive Sigma Paddle.

Optimize your compression

The relationship between pressure applied during compression of the breast and screening performance was recently investigated in the study “Performance of breast screening and cancer detection depends on mammography compression,” which was presented at the 13th International Workshop of Mammographic Imaging in Malmö, June 2016, and published in Breast Imaging (DOI:10.1007/978-3-319-41546-8_24). Researchers computed the compression pressure applied to a series of 113,464 screening mammograms. Screening performance measures were determined for each group. Cancer detection rate and the positive predictive value were optimal in the middle compression category.

 

We are driven to improve mammography and make it more woman-friendly. Our new Sensitive Sigma Paddle ensures that no excessive pressure is applied to the breast, thus improving detection of breast cancer and making the procedure more predictable, year after year.

 

Integrated design for any mammography system

The new innovative Sensitive Sigma Paddle is designed to seamlessly integrate with existing and new mammography systems. Therefore, the design looks much like the existing paddles. The paddle interface differs per mammography unit and must meet strict standards and regulations. The Sensitive Sigma Paddle is open to any mammography system. Please contact us to discuss the opportunities for your system.


Better quality and therefore clinical benefits

Successful clinical trials and experience with > 3.000 patients


Current breast compression guidelines and protocols are based on force. Indicated on the mammography unit in Newtons (N or daN). This results into a large variety of interpretations and a wide range of applied forces, where smaller breasts are relatively more compressed.


Graph breast compression current situation


The Sensitive Sigma Paddle has clear benefits

The Sensitive Sigma Paddle solves the current problems of under- and over-compression, by standardization on 75mmHg pressure. Under-compression results in images with too low contrast, motion artefacts and a higher average glandular dose (AGD). Over-compression results in unnecessary discomfort, vanishing tumors and negative patient or client perception. Clinical trials show positive results and improved experience1 with the use of Sensitive Sigma Paddle.


Compression with the Sensitive Sigma Paddle

 

75 mmHg as clear guideline

The procedure of breast positioning is exactly the same as usual, but when our paddle touches the breast, innovative sensors collect information about the breast which was not available before. This allows us to personalise breast compression and to take breast size and tissue stiffness into account. LED light indicators on the paddle light up while the pressure on the breast increases until the optimal pressure is reached. The radiographer is always in control of the compression, the Sensitive Sigma Paddle provides real-time visual feedback. If preferred, the last part of the compression can be done manually.

Optimal compression at 75mmHg

At a glance you can see when the optimum pressure is reached, preventing under- or over-compression. Standardization to75 mmHg is a clear guideline, resulting in the same physical experience without unnecessary pain, year after year.


Personalized compression

 

 

Personalized compression

The Sensitive Sigma Paddle measures each breast independently and optimizes the compression for each breast to 75 mmHg.

 

No unnecessary discomfort

 

No unnecessary discomfort or pain

At a glance you can see when the optimum pressure is reached. This information provides clear feedback and avoids excessive pressure being applied.

 

Standardize on pressure

 

 

Same physical experience
Pressure-standardized compression to 75 mmHg results in the same physical experience. The client or patient experience is more predictable, year after year.

Measure size and shape

 

Individual measurement
Innovative sensors measure each breast independently. Based on breast-size and tissue properties we are able to calculate the pressure to optimize the breast compression.

Similar Image Quality

 

Similar Image Quality
Scientific studies have shown that standardization based on pressure results in high quality x-ray images at least as good as before. Mammograms are excellent comparable, year after year.

Optimal compression

 

Avoidance of extreme pressures
A pressure-standardized protocol will avoid pressures that are too high or too low. This results in a more woman-friendly and optimized breast examination.
