Traditional ultrasound examination data from patients with thyroid cancer, including two-dimensional ultrasound images, color Doppler flow images, and detailed characteristics of thyroid nodules and lymph nodes such as number, size, morphology, echogenicity, margins, calcifications, and aspect ratio, will be collected. Prior to surgery, a reassessment will be conducted using AI-assisted ultrasound technology, and the detection and diagnostic results of thyroid nodules and lymph nodes by the AI system will be recorded. In cases where there is discrepancy between the results of two-dimensional ultrasound and the AI system, fine needle aspiration biopsy or intraoperative biopsy will be performed for further confirmation of their nature. Post-surgery, the pathological results of each nodule will serve as the \"gold standard\" for comparative analysis between the AI system and traditional two-dimensional ultrasound examinations. The accuracy of the AI system in detecting and localizing nodules will be analyzed, and its sensitivity, specificity, and accuracy will be calculated to evaluate its diagnostic efficacy and reliability in the preoperative assessment of thyroid cancer. Through this research, a more accurate and reliable adjunctive diagnostic method for the preoperative assessment of thyroid cancer is aimed to be provided to assist clinical decision-making.
