ABSTRACT

Objective: The patients having breast cancer increase, and the mortality from breast cancer increases, too. As for breast cancer, early detection is important, and mammography is the most common as this examination. A monitor diagnosis is common now for the interpretation of the mammogram. It is often diagnosed by gray indication in many institutions. However, there are some reports that the color display is higher in the detectability of the lesion than gray indication. As for the mammography, detection of the calcification is associated with detection of breast cancer. Also, a directly mass lesion may be detected. Therefore, the detectability was compared with the calcification and the mass lesion using ROC analysis for gray indication and color display. Methods: The 44 diagnosed oblique presentation images (five calcification, mass lesion three) in the past 3 years. In addition, we obtain the consent of the Ethical Review Board of the institution before a study. Each image was monitor interpretation and was gray by a color display and was changed the six kinds of yellow, green, cyan, blue, rainbow, and ROC analysis was performed about the presence of the lesion by the observer of six radiologists. Statistical analysis was conducted in the area AUC under the ROC curve and was compared about the lesion detectability of each color. Results: The AUC was significantly higher in yellow and cyan as compared with other colors.
