Shear wave elastography (SWE) and the Belgrade ultrasound enthesitis score (BUSES) may detect PF, but their comparative diagnostic performance is unclear. Objective: To compare SWE with the BUSES for identifying PF in individuals with and without AS. Methods: In this cross-sectional study, 96 participants were stratified into AS and non-AS populations, each further divided based on the presence or absence of clinical PF. Demographic data, the American Orthopedic Foot and Ankle Society Score (AOFAS), and the BASDAI score were recorded. All subjects underwent grayscale ultrasonography, the BUSES scoring, and SWE assessment of the plantar fascia. Logistic regression models were constructed for each population, controlling for age, body mass index (BMI), and fascia\u2013skin distance. ROC curve analyses were performed to evaluate diagnostic accuracy. Results: In both AS and non-AS groups, SWE and the BUSES were significant predictors of PF (p &lt; 0.05). SWE demonstrated slightly higher diagnostic accuracy, with area under the curve (AUC) values of 0.845 (AS) and 0.837 (non-AS), compared to the BUSES with AUCs of 0.785 and 0.831, respectively. SWE also showed stronger adjusted odds ratios in regression models. The interobserver agreement was good to excellent for both modalities. Conclusions: Both SWE and the BUSES are effective for PF detection, with SWE offering marginally superior diagnostic performance, particularly in AS patients. SWE may enhance the early identification of biomechanical changes in the plantar fascia.<\/jats:p>","DOI":"10.3390\/diagnostics15151967","type":"journal-article","created":{"date-parts":[[2025,8,5]],"date-time":"2025-08-05T15:56:16Z","timestamp":1754409376000},"page":"1967","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Diagnostic Accuracy of Shear Wave Elastography Versus Ultrasound in Plantar Fasciitis Among Patients with and Without Ankylosing Spondylitis"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5601-6392","authenticated-orcid":false,"given":"Mahyar","family":"Daskareh","sequence":"first","affiliation":[{"name":"Department of Radiology, University of California San Diego, San Diego, CA 92093, USA"},{"name":"Department of Radiology, Hospital of the University of Pennsylvania, Philadelphia, PA 19104, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahsa","family":"Mehdipour Dalivand","sequence":"additional","affiliation":[{"name":"Guilan Rheumatology Research Center, Department of Rheumatology, Razi Hospital, School of Medicine, Guilan University of Medical Sciences, Rasht 41346-14335, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4368-3772","authenticated-orcid":false,"given":"Saeid","family":"Esmaeilian","sequence":"additional","affiliation":[{"name":"Medical Imaging Research Center, Shiraz University of Medical Sciences, Shiraz 71348-14336, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aseme","family":"Pourrajabi","sequence":"additional","affiliation":[{"name":"Cardiovascular Diseases Research Center, Department of Cardiology, Heshmat Hospital, School of Medicine, Guilan University of Medical Sciences, Rasht 41448-95655, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seyed Ali","family":"Moshtaghioon","sequence":"additional","affiliation":[{"name":"Department of Orthopedic and Trauma Surgery, Shariati Hospital, Tehran University of Medical Sciences, Tehran 14117-13137, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8454-458X","authenticated-orcid":false,"given":"Elham","family":"Rahmanipour","sequence":"additional","affiliation":[{"name":"Immunology Research Center, Mashhad University of Medical Sciences, Mashhad 91779-48564, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmadreza","family":"Jamshidi","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, School of Medicine, Rheumatology Research Center, Shariati Hospital, Tehran University of Medical Sciences, Tehran 14117-13137, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Majid","family":"Alikhani","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, School of Medicine, Rheumatology Research Center, Shariati Hospital, Tehran University of Medical Sciences, Tehran 14117-13137, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad","family":"Ghorbani","sequence":"additional","affiliation":[{"name":"Orthopedic Research Center, Department of Orthopedic Surgery, Mashhad University of Medical Sciences, Mashhad 91379-13131, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2350010","DOI":"10.1142\/S0218957723500100","article-title":"Association among pain, skin blood flow and temperature, planta fascia and flexor digitorum brevis thickness, and foot function index in individuals with plantar fasciitis: A cross-sectional study","volume":"27","author":"Palee","year":"2023","journal-title":"J.
