Replace the needle with the material onto the syringe. 3. Keep the needle tip in contact with the slide’s surface with the bevel facing down at a 45° angle. This maneuver will prevent specimen dispersion and desiccation. 4. Gently express the specimen onto the surface of a nonfrosted glass slide. 5. Place the spreader slide onto the droplet, applying gentle pressure without crushing the droplet. 6. Draw the spreader slide along the length of the lower slide in a constant and steady manner. It is important to remember that the long axes of both glass slides must be perpendicular, but the flat surfaces parallel.
4a, b). Ultrasound features recapitulate the gross anatomy including a well-circumscribed hypoechoic fusiform lesion with well-defined margins and multiple punctate and or linear microreflectors that mimic microcalcifications; however, they show no posterior acoustic shadowing (Fig. 4c). The Patient with Thyroid Nodules Patients with thyroid nodules are candidates for USG-FNA. However, palpable “nodules” are not always true nodules by US in up to 30 % of patients, and a palpable “not nodular” thyroid gland may have a small and/or posterior nodule that may not be palpable, but may be amenable to USG-FNA.
Reposition the US probe over the marked skin to make sure that the biopsy site is centered in the screen display. 10. Clean all US gel from the skin. 11. Thoroughly disinfect the skin with alcohol. 12. Apply local 2 % lidocaine hydrochloride with epinephrine or epinephrine-free 3 % Carbocaine, using equipment available from dental supply stores. The syringe uses a 30-gauge disposable needle, a tubular 2-ml disposable cartridge of lidocaine or Carbocaine, and a reusable metallic injection handle.
