ABSTRACT
Background: A new system for the classification of galactograms is reported. To date, there is no universally accepted classification system. Purpose: To evaluate inter- and intra-observer agreement of the Galactogram Imaging Classification System (GICS) Material and Methods: Six observers with different levels of experience retrospectively evaluated 30 galactograms using the GICS. Images were reviewed independently twice within a four-week period. The kappa statistic was calculated for intra- and inter-observer variability. Results: The kappa for inter-observer agreement was moderate to substantial (range 0.41-0.72). Overall, the intra-observer kappa values were excellent (range 0.80-0.94). Conclusion: The present study shows a good to very good inter- and intra-observer agreement with the GICS. We believe the GICS can be incorporated into daily practice.
