In a sample of 101 cases selected randomly, the equal sign was clearly visualized in 97% (98\/101) of cases. It was visualized in sequence while examining the face or brain in 88% (89\/101). Mean time to visualize the equal sign was 28\u2009seconds. Total scan time increased by 1.5%. The body mass index had no effect on detection rate. Of the 5301 scans performed during the study period, there were 15 cases where the uvula was abnormal. Ten of these 15 cases had an intact lip. There were no false positive diagnoses of an abnormal uvula.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>It is feasible to image the equal sign at the midtrimester ultrasound with a low false positive detection rate.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jum.70221","type":"journal-article","created":{"date-parts":[[2026,3,8]],"date-time":"2026-03-08T17:07:43Z","timestamp":1772989663000},"page":"1707-1714","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Feasibility of Imaging the Uvula at the Midtrimester Anomaly Ultrasound"],"prefix":"10.1002","volume":"45","author":[{"given":"Anna Rose","family":"Sims","sequence":"first","affiliation":[{"name":"Department Obstetrics and Gynecology University of Stellenbosch  Cape Town South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2964-2237","authenticated-orcid":false,"given":"Lou","family":"Pistorius","sequence":"additional","affiliation":[{"name":"Department Obstetrics and Gynecology University of Stellenbosch  Cape Town South Africa"},{"name":"Panorama Perinatology Mediclinic Panorama  Cape Town South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denise","family":"Sproul","sequence":"additional","affiliation":[{"name":"Department Obstetrics and Gynecology University of Stellenbosch  Cape Town South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0406-8964","authenticated-orcid":false,"given":"Catherine Anne","family":"Cluver","sequence":"additional","affiliation":[{"name":"Department Obstetrics and Gynecology University of Stellenbosch  Cape Town South Africa"},{"name":"Panorama Perinatology Mediclinic Panorama  Cape Town South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,3,8]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/bdr2.2176"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2016.00067"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.6447"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10897-008-9152-5"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.7472"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.24888"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/jum.15163"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.5662\/wjm.v7.i3.93"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.7704"}],"container-title":["Journal of Ultrasound in Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jum.70221","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/jum.70221","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jum.70221","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,12]],"date-time":"2026-07-12T04:49:05Z","timestamp":1783831745000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jum.70221"}},"subtitle":["A Retrospective Study"],"short-title":[],"issued":{"date-parts":[[2026,3,8]]},"references-count":9,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2026,8]]}},"alternative-id":["10.1002\/jum.70221"],"URL":"https:\/\/doi.org\/10.1002\/jum.70221","archive":["Portico"],"relation":{},"ISSN":["0278-4297","1550-9613"],"issn-type":[{"value":"0278-4297","type":"print"},{"value":"1550-9613","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,3,8]]},"assertion":[{"value":"2024-12-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-02-16","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-03-08","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
