Abstract

High-quality radiographic positioning is essential for accurate diagnosis in knee imaging. Although artificial intelligence (AI) can assess image quality with high accuracy, its influence on radiographers' clinical decision-making remains unclear. This study examined whether AI feedback affects radiographers' acceptance or rejection of lateral knee radiographs.
Eighty-nine participants at European Congress of Radiology 2025 individually assessed 50 lateral knee radiographs (including six repeated cases), with or without AI-generated accept/reject annotations. A pretrained convolutional neural network classified femoral condyle alignment using an expert consensus reference standard. Diagnostic performance, inter-reader agreement (Gwet's AC), and intra-reader reliability (Cohen's kappa) were compared between groups.
Radiographers' sensitivity was identical with and without AI support (0.89), with no significant differences in specificity, PPV, or NPV. Inter-reader agreement was lower when AI annotations were shown (AC 0.233 vs. 0.374). There was a non-significant increase in agreement with AI for AI-experienced users, whereas agreement decreased among those without experience. False AI feedback reduced sensitivity and specificity in repeated cases, indicating susceptibility to incorrect AI advice.
AI feedback did not improve overall performance in assessing lateral knee positioning and may reduce consistency, particularly among users without AI experience. Radiographers demonstrated strong independent assessment skills, highlighting the importance of critical training when implementing AI in radiographic quality assurance.
These findings suggest that AI-based quality feedback should be implemented cautiously in radiographic practice, as it may unintentionally reduce consistency among radiographers, particularly those without prior AI experience. Targeted training in critical appraisal of AI outputs and staged integration into clinical workflows are essential to mitigate automation bias.
