The findings support guidelines encouraging individual patient decisions based on health status.
A study published in the American Journal of Roentgenology found that radiologists who compare prior mammograms with more than one image have better true-positive outcomes and fewer false-positives. This reduction in recall rates can lead to a decrease in anxiety, radiation exposure, biopsies, and healthcare costs for patients.
