Conclusion

The AI-based lesion detection shows high sensitivity with an acceptable level of false positives, potentially supporting the radiologist’s workflow. By adjusting the cut-off value, false positives can be reduced but sensitivity also decreases. Thus, different operating points may be appropriate depending on the expected prevalence of cancer in the studied cohort.
