Aim: To investigate how breast radiologists from Jordan and Australia differ in accuracy when examining the set of test screening cases. Materials & methods: A total of 27 Jordanian and 115 Australian breast radiologists were requested to read 60 mammographic images and to indicate the location of any perceived lesion and record a confidence level ranging from 1 to 5. Jackknife alternative free-response receiver operating characteristic, location sensitivity and specificity were calculated and compared for both Australian and Jordanian readers. Results: Australian readers achieved significantly higher readings accuracy than Jordanian readers retrospectively in terms of Jackknife alternative free-response receiver operating characteristic (75th percentile values: 0.863 vs 0.600; p = 0.001) and location sensitivity (75th percentile values 0.673 vs 0.571; p = 0.022). Conclusion: Australian radiologists achieved higher performance in reading breast mammograms than Jordanian radiologists.
