How more pixels get more out of a mammogram

Breast imaging is about the details. Studies report that 70% of radiology errors directly result from the failure to perceive a radiographic abnormality. Apparently, mammographs and chest radiographs expose radiologists to the greatest risk in this regard2. In fact, breast cancer seems to be the most frequently missed diagnosis in radiology!3

No wonder there are strict guidelines in place when it comes to mammography imaging. To ensure that the smallest details in a digital mammogram are visible on your screen, the ACR (American College of Radiology) guideline recommends that display device specifications should match the acquisition software resolution matrix as closely as possible.

Why? At acquisition, the native resolution of digital mammography images is so high (see table below) that you need at least 5 million pixels (or 5 megapixels) per display to effectively view them. Only then, enough of the picture elements – and hence important image details such as subtle masses and calcifications – will be reproduced when viewed on screen.

For digital breast imaging, a dual-head 5MP display is only the absolute minimum. Providing additional pixels can lead to even better detection. This is confirmed by a 2014 study about the wants and needs of radiologists where 80% of radiologists said that higher spatial resolution would improve their reading experience4.

Resolution is one thing, but clinical accuracy is another. There's so much more to consider when it comes to breast screening. Read the full story in the Why you need a 5MP display for mammography screening ebook and learn how to:
