Improving on the Do‐It‐Yourself Ultrasound‐Guided Fine‐Needle Aspiration Simulation Phantom

The increasing use of ultrasound (US) for the diagnostic workup of thyroid lesions has subsequently been met with an increasing demand for effective US and US‐guided fine‐needle aspiration models. Although numerous do‐it‐yourself phantoms have been previously described, to our knowledge, this is the first to describe a more realistic US thyroid model using inexpensive consumer‐grade materials. A simple phantom was developed and successfully used to obtain US images that realistically mimic thyroid anatomy and echogenicity. The phantom was constructed for a total cost of $6.69. It served as an inexpensive and anatomically realistic means to simulate thyroid US and US‐guided fine‐needle aspiration.
