Sperimentale: AI-Assisted Preoperative Review
Participants undergo standard preoperative thyroid ultrasonography followed by a standardized AI-assisted repeat examination and surgeon-led review incorporating the locked AI system's thyroid-nodule output.
The AI system does not assess cervical lymph nodes.
All supplementary examinations and final diagnostic and surgical decisions are made by clinicians.
|
After standard preoperative ultrasonography, the same participant underwent a standardized AI-assisted repeat examination.
The locked system identified and classified thyroid nodules and provided malignancy-score information for surgeon-led review.
It did not assess cervical lymph nodes and was not retrained or recalibrated during the study.
Additional fine-needle aspiration, intraoperative pathologic examination, and surgical management were determined by clinicians using the complete clinical assessment.

Each participant is counted once regardless of the number of examinations.
The decision remained clinician led; cervical lymph-node examinations were outside the AI system's task.

Lasso di tempo: From completion of the AI-assisted review through surgery
