Methods: Consecutive PsA patients attending our unit were asked to participate. HCs and agonist athletes were enrolled as a control group. A bilateral PDUS evaluation of Achilles tendons was performed in order to evaluate the EF in all patients and controls. Results: In total, 30 PsA patients, 40 athletes and 20 HCs were enrolled. The median (IQR) EF thickness among the PsA patients, athletes and HCs was 0.035 cm (0.028\u20130.04) cm, 0.036 (0.025\u20130.043) cm and 0.030 (0.020\u20130.038) cm, respectively (p = 0.05 between PsA patients and HCs). The intra-reader reliability was excellent [ICC (95% CI) of 0.91 (0.88\u20130.95)] and the inter-reader reliability was good (0.80 (0.71\u20130.86). The assessment of EF was feasible, with a mean time of 2 min. No correlations were found with disease activity indices in PsA patients. Conclusion: The assessment of EF is a feasible and reproducible test and may be explored as a potential imaging biomarker.<\/jats:p>","DOI":"10.3390\/diagnostics13081446","type":"journal-article","created":{"date-parts":[[2023,4,18]],"date-time":"2023-04-18T01:36:45Z","timestamp":1681781805000},"page":"1446","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Ultrasonographic Evaluation of Entheseal Fibrocartilage in Patients with Psoriatic Arthritis, Athletes and Healthy Controls: A Comparison Study"],"prefix":"10.3390","volume":"13","author":[{"given":"Fabio Massimo","family":"Perrotta","sequence":"first","affiliation":[{"name":"Dipartimento di Medicina e Scienze della Salute \u201cVincenzo Tiberio\u201d, Universit\u00e0 degli Studi del Molise,  86100 Campobasso, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Ronga","sequence":"additional","affiliation":[{"name":"Orthopedics and Trauma Operative Unit, Department of Health Sciences, University of Piemonte Orientale, 13100 Novara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Silvia","family":"Scriffignano","sequence":"additional","affiliation":[{"name":"Dipartimento di Medicina e Scienze della Salute \u201cVincenzo Tiberio\u201d, Universit\u00e0 degli Studi del Molise,  86100 Campobasso, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6189-5328","authenticated-orcid":false,"given":"Ennio","family":"Lubrano","sequence":"additional","affiliation":[{"name":"Dipartimento di Medicina e Scienze della Salute \u201cVincenzo Tiberio\u201d, Universit\u00e0 degli Studi del Molise,  86100 Campobasso, Italy"},{"name":"Department of Development and Regeneration, Skeletal Biology and Engineering Research Center, KU Leuven University, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1428","DOI":"10.3899\/jrheum.190054","article-title":"Psoriatic Arthritis, Psoriatic Disease, or Psoriatic Syndrome?","volume":"46","author":"Lubrano","year":"2019","journal-title":"J.
