Fine-needle aspiration biopsy (FNAB) of thyroid nodules has resulted in fewer @entity1 needing thyroidectomy. Nondiagnostic FNAB specimens may require surgery for diagnosis. Ultrasound can help decrease nondiagnostic biopsies by visualizing lesions and guiding biopsy needles. Between 1996 and 1997, 76 @entity1 had ultrasound-guided needle biopsies of thyroid nodules. Sixteen @entity1 had clearly palpable nodules, whereas 19 were described as difficult to palpate. There were 32 @entity1 who presented with either prominent thyroids or enlarged lobes. Six @entity1 presented only with nonspecific symptoms, and 3 had nodules discovered incidentally on imaging studies. Biopsies were diagnostic in 73 of 76 (96%) @entity1 . This varied with the size of the nodule, with the rate of nondiagnostic biopsies being 13 per cent in lesions <1.0 cm and 3 per cent in lesions >2.0 cm. Fifteen @entity1 had surgery based on the FNAB, with a surgical yield of malignancy of 47 per cent. Ultrasound-guided FNAB is extremely useful in evaluating @entity1374 that are difficult to palpate or nonpalpable, as well as the remainder of the gland and surrounding structures. The use of ultrasound guidance in performing FNAB results in a low rate of nondiagnostic biopsies, which may decrease the number of unnecessary thyroidectomies performed to rule out malignancy.
