A new paper explores how the position of a lung nodule within a CT scan's reconstruction cycle, known as z-phase, can significantly impact the sensitivity of AI-based detection systems. The study found that when the ratio of the reconstruction interval to the nodule diameter is 1.0 or greater, z-phase becomes a major factor in detection variance, a stochastic effect not captured by current quality metrics or AI confidence scores. This suggests that AI performance in medical imaging can be influenced by subtle, protocol-level variations. AI
