Background: Ultrasound guided fine-needle aspiration biopsy (UG-FNAB) is the main presurgical, minimally invasive, accurate and generally safe procedure for the diagnosis of thyroid pathology. At present it is recommended as a valuable diagnostic tool for the management of thyroid nodules.
Objectives: This study aimed to evaluate if a radiologist's assistance in the UG-FNAB procedure decreased the rate of unsatisfactory biopsies.
Material and methods: Over a 3-year period, 385 (100%) patients were enrolled to the study. All individuals had UG-FNAB performed for the first time due to multiple nodules of the thyroid gland. Patients with a family history of thyroid cancer, receiving radioactive iodine and other predispositions for thyroid malignancy were excluded. 184 (47.79%) patients were examined using UG-FNAB with a radiologist's assistance (group 1) and 201 (52.21%) without such support (group 2). All biopsies were performed by the same surgeon. All specimens obtained were examined by two cytologists experienced in thyroid pathology.
Results: The specimens from the UG-FNAB were more frequently diagnostic when obtained from procedures performed with a radiologist's assistance (77.8% vs. 56.8%, p < 0.0001). The cellularity of the specimens obtained from the UG-FNAB performed with a radiologist's assistance was higher than those obtained without such support (66.7% vs. 56.9%, p < 0.0001).
Conclusions: UG-FNAB of the thyroid nodules performed with a radiologist's assistance makes it possible to obtain more valuable specimens, which may improve diagnostic accuracy in the preoperative management of thyroid pathology.
