Background: A recent study using dedicated contrast-detail phantoms showed that the image quality of a 3-megapixel (M) monitor can approach that of a 5M monitor in digital mammography. Purpose: To compare a 5M cathode ray tube (CRT) monitor with a 3M liquid crystal display (LCD) monitor for soft-copy reading of digital mammography of microcalcifications in a clinical setting. Material and Methods: 100 screen-detected microcalcification lesions (34 malignant and 66 benign) without mass that had been evaluated with 11-gauge stereotactic vacuum-assisted breast biopsy or definitive surgery were recruited into the study. One radiologist analyzed the soft-copy mammograms on a 5M CRT monitor and a 3M LCD monitor with 5 months between interpretations and scored the likelihood of malignancy and calcification distribution on a five-point scale. Calcification morphology and breast density were scored on a four-point scale. Positive predictive value (PPV) and negative predictive value (NPV) were calculated on the basis of a Breast Imaging Reporting and Data System. The interpretation time was also measured. Results: There was no significant difference in the likelihood of malignancy ( P = 0.655), calcification morphology ( P = 0.168), calcification distribution ( P = 0.11), and breast density ( P = 0.0608). The PPV and NPV of soft-copy reading on the 5M CRT monitor was 57% (30/53) and 91% (43/47), respectively, identical to the results using the 3M LCD monitor. The total interpretation time averaged 88 s for the 5M CRT monitor and 67 s for the 3M LCD monitor ( P<0.0001). Conclusion: Soft-copy reading of a digital mammography of microcalcifications with a 3M LCD monitor was similar in diagnostic performance to a 5M CRT monitor in this study.
