OBJECTIVES To determine the optimal needle size (23-gauge or 27-gauge) for ultrasound-guided fine-needle aspiration biopsy of thyroid nodules and to compare the interoperator yield for this procedure. PATIENTS AND METHOD Over an 11-month period, 123 patients underwent biopsy of a thyroid nodule. Three experienced radiologists were assigned at random to sample the nodules. For each nodule, four passes were performed in random order, two with 23-gauge needles and two with 27-gauge needles. If a… CONTINUE READING
