Ultrasound signals at a lateral neck site were obtained via a single\u2010element ultrasonic transducer with synchronous videofluoroscopic swallowing studies images of swallows of differing viscosities in 21 adult dysphagia outpatients. Characteristic ultrasound features were extracted to differentiate a bolus\u2010filled from a collapsed esophagus. From 21 subjects, 412 swallows exhibited 4 reproducible waveform patterns associated with bolus transit as displayed in a heatmap: (1)\u00a0<jats:italic>Strong Reflectors<\/jats:italic>; (2)\u00a0<jats:italic>Echo Shifts<\/jats:italic>; (3)\u00a0<jats:italic>Distal Acoustic Enhancement<\/jats:italic>; and (4)\u00a0<jats:italic>Speckling<\/jats:italic>: One or more of these features were observed in the swallow series for all 21 subjects. Distinct acoustic waveform features acquired by single\u2010element ultrasonic transducers can identify bolus transit through the cervical esophagus.<\/jats:p>","DOI":"10.1002\/ohn.746","type":"journal-article","created":{"date-parts":[[2024,4,5]],"date-time":"2024-04-05T06:35:55Z","timestamp":1712298955000},"page":"919-922","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Noninvasive Bolus Transit Detection in Cervical Esophagus Utilizing Ultrasound Characteristics"],"prefix":"10.1002","volume":"171","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9869-8352","authenticated-orcid":false,"given":"Andrew S.","family":"Wilcox","sequence":"first","affiliation":[{"name":"RefloDx, Inc Kaysville Utah USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William D.","family":"Jackson","sequence":"additional","affiliation":[{"name":"University of Utah Primary Children's Hospital Salt Lake City Utah USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0148-0750","authenticated-orcid":false,"given":"Amanda C.","family":"Heller\u2010Stark","sequence":"additional","affiliation":[{"name":"University of Utah Salt Lake City Utah USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elizabeth L.","family":"Lanza","sequence":"additional","affiliation":[{"name":"University of Utah Salt Lake City Utah USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4778-9999","authenticated-orcid":false,"given":"Julia K.","family":"Ellerston","sequence":"additional","affiliation":[{"name":"University of Utah Salt Lake City Utah USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,4,5]]},"reference":[{"key":"e_1_2_7_2_1","unstructured":"JacksonWD.AHSA \u201cAerodigestive Disorders\u201d practice portal.
