A Catholic University of Korea research team will present its research examining the visually lossless threshold for compressing full-field digital mammography (FFDM) images.

To estimate the acceptable compression ratio for FFDM images, the researchers performed JPEG 2000 lossy compression of 80 images at eight compression ratios, according to co-author Sung Hun Kim, MD.

The researchers found that all 80 studies were indistinguishable at 20:1 and 40:1 compression. At 60:1, 77 (96.2%) of 80 were indistinguishable.
