AB - Purpose: This study assessed whether varying the color of the display improves the detectability of
microcalcifications on mammography.
Materials and Methods: The American College of Radiology (ACR) 156 mammographic phantom was
imaged under three different conditions. Ten observers evaluated the depiction of 30 phantom
microcalcifications presented in six color-scales: red, green, yellow, blue, and cyan. Differences in the
detectability of macrocalcifications and eye and psychological fatigue among the different color scales were
assessed.
Results: Yellow-scale images improved the detectability of microcalcifications to a significantly greater
extent than did the other colors: relative to blue and red, P < 0.01; relative to gray, green, and cyan, P <
0.05. The cyan display induced the least eye fatigue. While no difference in eye fatigue induced by the
yellow and gray displays was found, displays of these colors were associated with significantly less eye
fatigue than the green-scale (P < 0.01), red-scale, and blue-scale displays (P < 0.001).
Conclusion: The detectability of microcalcifications on mammography can be improved by changing the
color scale in which mammograms are visualized from gray to yellow.
