概要 OBJECTIVE:To assess the clinical performance of three-dimensional stereoscopic digital mammography (3DsDM) compared with two-dimensional digital mammography (2DDM) for breast lesion diagnosis with jackknife free-response receiver operating characteristics (JAFROC) observer study.METHODS:Forty pairs of standard-dose 2DDM and their 3DsDM images were used for an observer performance study. A total of 18 lesions were identified as the reference standard of actionable breast lesions (BI-RADS category 3 or more) by 2 breast radiologists. Ratings and locations of "lesions" determined by observers were utilized for assessing the statistical significance of differences between 8 radiologists' performances with the 2DDM images and with the 3DsDM images in JAFROC analysis.RESULTS:The average figure-of-merit values for all radiologists increased to a statistically significant degree, from 0.859 with the 2DDM images to 0.936 with the 3DsDM images (P<.001). The average sensitivity for detecting actionable lesions was improved from 74.3 % to 92.4 % at a false-positive rate of 0.2 per case by use of the 3DsDM images. The mean reading time per case with 2DDM images was not significantly different from that with 3DsDM images.CONCLUSION:The use of 3DsDM would improve the observer performance for breast lesion without considerably extending the reading time. Advances in knowledge: Use of 3DsDM improves radiologists' performance for breast lesion detection.
