Abstract Objective: This study investigated the clinical value of ultrasound-guided fine-needle aspiration biopsy (US-FNAB), computed tomography (CT) and BRAFV600E combination for papillary thyroid carcinoma (PTC) diagnosis. Subjects and methods: A total of 300 patients with thyroid nodules were assigned to the PTC group (n = 184) and the nodular goiter (NG) group (n = 116). The positive detection rates of US-FNAB, CT and BRAFV600E gene mutation and their relationship with tumor number, tumor diameter, lymphatic metastasis, capsule invasion and tumor-node-metastasis […]
