Dr. Theodore Dubinksy reviews the conventional use of ultrasound imaging to detect and diagnose thyroid nodules, including fine needle biopsies. He then explains how ultrasound elastography, a newly developed technique, to analyze the stiffness of non-palpable nodules by measuring the amount of distortion from the carotid artery, an highlights the results of this method, as well as the potential for this technique to replace fine needle aspirations as a means for diagnosing thyroid nodules.
