Radiology resident recognized for research into compressing mammograms for accurate and speedy electronic transmission.
Research aimed at improving early breast cancer detection by making mammogram images easier to transmit via the Internet has earned a fourth-year radiology resident the 2014 Residents in Radiology Executive Council Award.
This award, given to only three residents, was presented to Mark Kovacs, a resident at the Santa Barbara Cottage Hospital, at the American Roentgen Ray’s annual meeting in San Diego, where he presented his research.
Kovacs investigated a method that would allow mammograms to be easily transmitted electronically and without affecting diagnostic accuracy. Kovacs found the solution in lossy data compression, a technique that removes data from files and reduces the file size to one-eightieth of its original size. A typical four-view mammogram is 200 megabytes, but the reduced size with lossy data compression was only 2.5 megabytes, which is about the size of a cell phone photo and easily transmittable via the web.
To confirm the compression didn’t affect diagnostic accuracy, Kovacs conducted a study of 194 patients, which revealed that participating mammographers were able to accurately detect the presence of early stage breast tumors as small as 1 centimeter in diameter in mammograms that received the lossy data compression.
“Studies show that the number one factor in increasing breast cancer detection rates is the experience of the physician reading the mammogram,” Kovacs said in a release. “One of the limiting factors in getting screening mammograms to expert readers is the enormous file size of full-field digital mammograms. If the Federal Drug Administration allowed the use of lossy compressed mammograms for primary interpretation, it could usher in a new era of practical tele-mammography that could help improve early detection rates for breast cancer.”

The Reading Room Podcast: Current and Emerging Insights on Abbreviated Breast MRI, Part 2
July 23rd 2025In the second part of a multi-part podcast episode, Stamatia Destounis, MD, Emily Conant, MD and Habib Rahbar, MD, discuss key sequences for abbreviated breast MRI and how it stacks up to other breast cancer screening modalities.
Considering Breast- and Lesion-Level Assessments with Mammography AI: What New Research Reveals
June 27th 2025While there was a decline of AUC for mammography AI software from breast-level assessments to lesion-level evaluation, the authors of a new study, involving 1,200 women, found that AI offered over a seven percent higher AUC for lesion-level interpretation in comparison to unassisted expert readers.
Can Contrast-Enhanced Mammography be a Viable Screening Alternative to Breast MRI?
June 17th 2025While the addition of contrast-enhanced mammography (CEM) to digital breast tomosynthesis (DBT) led to over a 13 percent increase in false positive cases, researchers also noted over double the cancer yield per 1,000 women in comparison to DBT alone.
