We examined the significance of cervical elastography in the last trimester of pregnancy. Cervical elastography was performed at weekly checkups after 36\u00a0weeks of gestation in 238 cases delivered at our hospital from 2017 to 2018. The correlation with the onset time of natural labor, which is an index for judging maternal delivery preparation status, was examined. A total of 765 examinations were conducted, and cervical stiffness determined by cervical elastography was positively correlated with the Bishop score (r\u2009=\u20090.46, p\u2009&lt;\u20090.0001). When examined separately for each week, only the examinations performed at 39\u00a0weeks were associated with the onset of spontaneous labor up to 7\u00a0days later (p\u2009=\u20090.0004). Furthermore, when stratified and analyzed by the Bishop score at 39\u00a0weeks of gestation, cervical elastography was associated with the occurrence of spontaneous labor pain for up to seven days in the groups with Bishop scores of 3\u20135 and 6\u20138 (p\u2009=\u20090.0007 and p\u2009=\u20090.03, respectively). In conclusion, cervical elastography at 39\u00a0weeks of pregnancy is useful for judging the delivery time.<\/jats:p>","DOI":"10.1038\/s41598-020-76753-4","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T11:02:41Z","timestamp":1605178961000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Relationship between cervical elastography and spontaneous onset of labor"],"prefix":"10.1038","volume":"10","author":[{"given":"Yoshie","family":"Yo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasushi","family":"Kotani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reona","family":"Shiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiko","family":"Yamamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Risa","family":"Fujishima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hisamitsu","family":"Takaya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayako","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masao","family":"Shimaoka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noriomi","family":"Matsumura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2020,11,12]]},"reference":[{"key":"76753_CR1","unstructured":"Bishop, E.H.
