Ultrasound and SWE examinations were performed before the procedure and again 8 to 10 weeks after FNAB. Nodule stiffness was measured in kilopascals (kPa) during both evaluations, and changes in elasticity were assessed.Results: The mean SWE stiffness of the nodules significantly decreased from 21.80 \u00b1 11.43 kPa before FNAB to 17.83 \u00b1 9.98 kPa after FNAB (p = 0.001). Smoking status and serum free T3 levels were significantly associated with changes in SWE stiffness (p &lt; 0.05). However, no significant difference was observed between TIRADS 3 and TIRADS 4 categories regarding the change in stiffness (p = 0.223).Conclusion: This study demonstrates a significant reduction in thyroid nodule stiffness after FNAB as measured by SWE. These post-biopsy changes may lead to potential misinterpretations in subsequent elastographic evaluations, possibly affecting diagnostic accuracy and clinical decision-making.<\/jats:p>","DOI":"10.11152\/mu-4533","type":"journal-article","created":{"date-parts":[[2025,7,29]],"date-time":"2025-07-29T05:29:30Z","timestamp":1753766970000},"page":"27","source":"Crossref","is-referenced-by-count":0,"title":["Effect of fine needle aspiration biopsy on change in thyroid nodule elasticity"],"prefix":"10.11152","volume":"28","author":[{"given":"Mehmet","family":"Ak\u00e7i\u00e7ek","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nurullah","family":"Da\u011f","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lezan","family":"Keskin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B\u00fclent","family":"Petik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Serkan","family":"\u00dcnl\u00fc","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4840","published-online":{"date-parts":[[2026,3,18]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/4533\/2667","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/4533\/2667","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T17:39:33Z","timestamp":1773855573000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/4533"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,18]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026,3,18]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-4533","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2026,3,18]]}}}
