A new research paper highlights a critical, unmonitored variable in medical imaging AI: the acquisition state. The study demonstrates that changes in reconstruction kernels, even when patient and acquisition parameters are identical, can significantly alter AI-measured nodule sizes and even flip classification categories. This instability, invisible to standard DICOM metadata, affects detection confidence and measurement reliability differently based on noise and frequency content, necessitating acquisition-aware validation for AI accreditation.
