Article Synopsis
- The study aimed to investigate differences in diagnostic and perceptual performance among radiologists when detecting left-sided versus right-sided breast cancers and microcalcifications.
- Eight radiologists evaluated 100 digital mammograms over multiple reads, including both original and mirrored images, to assess their performance in cancer diagnosis and microcalcification detection.
- The results indicated no statistically or clinically significant differences in detection rates between left and right sides, with slightly more left-sided cases correctly identified, but these differences were not significant (P-values of 0.28 and 0.74).
Introduction: The purpose of this study was, for a group of experienced radiologists, to identify the magnitude of and statistical significance of intrareader variability in mammographic diagnostic performance or cancer diagnosis and mammographic perceptual performance or microcalcification detection.
Methods: Eight radiologist readers (8-30 years experience in radiology, five current BreastScreen readers) read a set of 100 digital mammograms on two separate reads with random case orders. Twenty-three of the 100 had proven malignancies, and 52 of the 100 had confirmed microcalcifications.
Introduction: Picture archiving and communication systems images designed to be viewed on high-resolution medical-grade monitors are routinely viewed on office-grade monitors on the wards or at home. This study aimed to determine whether a statistically significant difference in diagnostic (cancer detection) and perceptual (microcalcification detection) performance exists between 3MP grade and 1MP office-grade monitors.
Methods: 3MP Dome medical-grade liquid crystal display (LCD) monitors (Planar, Beaverton, OR, USA) were compared to 1MP Dell office-grade LCD monitors (Dell Inc, Round Rock, TX, USA).
