Using a 3\u2010 to 5\u2010MHz curvilinear transducer, the transverse section of the collapsed esophagus was imaged in the area behind the heart. The probe was rotated 90 degrees to identify the longitudinal section of the esophagus which was then traced along its entire length.<\/jats:p><\/jats:sec><jats:sec><jats:title>Result<\/jats:title><jats:p>This study shows that the collapsed, echogenic, transverse section of the esophagus was persistently seen in the area behind the heart, in more than 99% of fetuses in both the groups. It was a useful starting point to image the longitudinal section of the esophagus in both the groups, particularly in the 18 \u2010 30 week group. Using this technique, the entire length of the esophagus could be traced in 92.3% of 18 \u2010 30 week fetuses and 88.23% of the 11 \u2010 14 week fetuses.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A collapsed transverse section of the esophagus was persistently and easily seen as a bright echogenic structure in the area behind the heart in more than 99% of fetuses in all 3 trimesters (in both the groups) and, therefore, was an ideal starting point to begin tracing the esophagus in its longitudinal axis.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jum.14646","type":"journal-article","created":{"date-parts":[[2018,4,17]],"date-time":"2018-04-17T04:20:18Z","timestamp":1523938818000},"page":"2863-2872","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Simple and Easy Technique for Imaging the Fetal Esophagus in the First, Second, and Third Trimesters Using the Transverse Section of the Esophagus in the Area Behind the Heart as a Reference Point"],"prefix":"10.1002","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2513-274X","authenticated-orcid":false,"given":"Priti","family":"Venkatesh","sequence":"first","affiliation":[{"name":"Manipal Hospital Bangalore India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,4,16]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/pd.341"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1996.15.5.417"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1998.11020138.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2016.02.001"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1994.13.3.175"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.1091"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gyobfe.2007.01.016"}],"container-title":["Journal of Ultrasound in Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjum.14646","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jum.14646","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/jum.14646","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jum.14646","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,7]],"date-time":"2023-09-07T04:59:56Z","timestamp":1694062796000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jum.14646"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,4,16]]},"references-count":7,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2018,12]]}},"alternative-id":["10.1002\/jum.14646"],"URL":"https:\/\/doi.org\/10.1002\/jum.14646","archive":["Portico"],"relation":{},"ISSN":["0278-4297","1550-9613"],"issn-type":[{"type":"print","value":"0278-4297"},{"type":"electronic","value":"1550-9613"}],"subject":[],"published":{"date-parts":[[2018,4,16]]},"assertion":[{"value":"2017-11-01","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-02-23","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-04-16","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
