How mammography displays impact a radiologist’s reading routine
In a previous article, we focused on the importance of display resolution and luminance. These characteristics have an enormous impact on the way breast radiologists interpret mammograms and other breast images. When you’re buying a new mammography display, you should also think about the impact on ergonomics and productivity. In this article, we will look at multimodality workflow and reading ergonomics. With the right medical display, you can go a long way.
Multimodality workflow in breast imaging
Several studies have shown that detection of breast cancers is more accurate when combining multiple types of breast studies. When screening dense breasts, for example, mammography alone is not enough. Additional imaging methods, such as breast tomosynthesis, breast MR or ultrasound are required. And in some places it is now a requirement to use an imaging technique other than 2D mammography alone.
Viewing color modalities such as breast ultrasound and MRI requires a color mammography display system. In addition, the colors presented on screen need to be consistent and calibrated. This is already the case for grayscale images where DICOM GSDF defines the accuracy of the image. Barco has developed a special calibration technology for color displays called SteadyColor™ which assures that color images on Barco mammography displays are consistent and distinguishable.
Barco’s Nio 5MP and Coronis Uniti® displays offer color calibration to ensure confident multimodality breast imaging.
2D vs 3D mammography
You should also verify that the display is designed for 3D mammography. It can take more time to diagnose digital breast tomosynthesis studies than 2D mammography exams because radiologists must scroll or cine through many images or slices.
At the same time, it is more challenging to clearly detect microcalcifications in moving images. Our displays have proven to ensure 10% higher detection while scrolling digital breast tomosynthesis images compared to traditional mammography displays.1 With our RapidFrame™ technology, moving through DBT datasets is crisp and in-focus , with no blurring.
Reduced eye fatigue
Another big challenge for radiologists today is reading ergonomics. Eye fatigue is one of the most prevalent problems for radiologists. Barco displays offer a high calibrated brightness as well as integrated features to optimize the ambient environment in the reading room, ensuring the best possible reading conditions.
Another major cause of discomfort is neck strain, which results from frequent head movements when viewing images on multiple screens. That’s why the design of the unique 33” screen of Barco’s Coronis Uniti® eliminates the distraction of the center bezel present on a dual 5MP display system. It is designed to mirror a human’s natural field of vision to minimize head, neck and eye movement.
A display design that matches the human’s natural field of vision can minimize head, neck and eye movement for radiologists.
Radiologists need a smooth and efficient reading routine. To achieve this, use a mammography display fit for multimodality imaging. It means you’ll be able to read any type of breast image, in color or grayscale, on the same screen. Ideally, the color display not only ensures calibration of grayscale images but of colors as well. With additional built-in features designed to improve ergonomics, you can truly perfect your reading routine during breast screening.
