Development of a nomogram for preoperative prediction of malignant risk in thyroid follicular tumors based on multimodal ultrasound and clinical features: A retrospective observational study
Background Preoperative differentiation of thyroid follicular tumors remains challenging because cytology has a limited ability to assess capsular and vascular invasion. This study aimed to develop a nomogram integrating multimodal ultrasound and clinical features to predict the risk of malignancy in follicular thyroid...
