Radiology with less radiation: accurate low-dose mammography

Medical Imaging & workflows 2 min read last updated on: Aug 23, 2018

For women over 45, annual breast screening is recommended. However, the impact of radiation dose is a concern for most healthy women. What if radiologists could get the same results with less radiation? Well, they can, thanks to a clinical tool called SpotViewTM.

Producing high-quality breast images with less radiation can take away some of the concerns women have about breast screening. That’s why manufacturers are investigating new ways to reduce the radiation dose of image acquisition, which are just as reliable as conventional tools.

In line with this evolution, Barco continuously optimizes the image quality of its medical display systems and also develops clinical tools to increase visibility of subtle details in breast images.

A lower radiation dose

One of these tools is SpotView, which increases medical display luminance in a region of interest to help radiologists detect small details. A new clinical study, conducted by Dr. Elizabeth A. Krupinski, found that with SpotView it may be possible to reduce mammography radiation dose without impacting diagnostic accuracy.

Compared to a mammography display with a calibrated luminance of 420 candela (recommended by the American College of Radiology), radiologists using SpotView get the same percent correct (Pc) with a lower radiation dose.1

"SpotView can decrease errors of perception and I have found it to be helpful in maintaining my focus when scanning patterns are made difficult by distractions or eye fatigue. I have found abnormalities using SpotView even though I thought I had finished searching a case."
Dr. James Ruiz, Radiologist and Breast Imaging Specialist at Woman’s Hospital in Baton Rouge

Faster, more accurate detection

The study also indicates that SpotView positively impacts interpretation efficiency. On a typical mammography display, SpotView increases the reading accuracy by 6% and decreases the reading time by 16%. Imagine how this might help radiologists with their heavy workload, not to mention the impact on the detection of hard to find cancers.
