Thyroid gland biopsy


For examination and puncture of the thyroid gland, a linear ultrasound (US) probe with high contrast is ordinarily used (10–15 MHz). Patients with large struma often require a US sound probe with better tissue penetration (lower ultrasound frequency) for a satisfactory result, however, this reduces the contrast detail significantly.

For the cytology biopsy, a 27 G needle is used, or sometimes a 25 G needle is used.

For the histological biopsy, a biopsy gun is used for automatic biopsy taking with a biopsy needle size 16-18 G.
