The time added to radiologists' interpretations of screening mammograms by the use of computer-aided detection is an important consideration in the assessment of the efficiency of digital mammography interpretation
The additional time required to review CAD images represented a 19% increase in the mean interpretation time without CAD.
CAD requires a considerable time investment for digital screening mammography but may provide less measurable benefits in terms of confidence of the radiologists

Purpose: To evaluate the mammographic features of breast cancer that favor lesion detection with single reading and computer-aided detection (CAD) or with double reading
Results: A total of 227 cancers were detected in 28 204 women. A total of 170 cases were recalled with both reading regimens. Lesion types were masses (66%), microcalcifications (25%), parenchymal deformities (6%), and asymmetric densities (3%). The ability of the reading regimens to correctly prompt the reader to recall cases varied significantly by lesion type (P < .001). More parenchymal deformities were recalled with double reading, whereas more asymmetric densities were recalled with single reading with CAD. There was no difference in the ability of either reading regimen to prompt the reader to correctly recall masses or microcalcifications. CAD correctly prompted 100% of microcalcifications, 87% of mass lesions, 80% of asymmetric densities, and 50% of parenchymal deformities. CAD correctly marked 93% of spiculated masses compared with 80% of ill-defined masses (P = .054). There was a significant trend for cancers detected with double reading to occur only in women with a denser mammographic background pattern (P = .02). Size had no effect on lesion detection.
Conclusion: Readers using either single reading with CAD or double reading need to be aware of the strengths and weaknesses of reading regimens to avoid missing the more challenging cancer cases

Our study contributes important information to existing literature in that we identified six performance cut points important for interpretation of screening mammograms and found that most of the cut points we identified would affect between 20% and 49% of interpreting physicians, who might benefit from additional training to improve their mammogram interpretation skills
