Cost calculation of ultrasound-guided thyroid fine-needle aspiration biopsy strategy. Cost of diagnostic steps were summed until a final diagnosis was established for one hundred thyroid nodules for which initial ultrasound-guided thyroid fine-needle aspiration biopsy was performed by simulating American Association of Clinical Endocrinologists thyroid nodule management guideline. Strategy cost was calculated by dividing the total cost to 100. FNA: fine-needle aspiration biopsy, USG: ultrasonography.
