We used magnetic resonance imaging (MRI) pelvimetry to predict the probability of vaginal delivery and distinguish the cephalopelvic disproportion risk in women with prolonged active labour. Methods: This prospective cohort study enrolled term nulliparous women willing to undergo MRI pelvimetry and a trial of labour. A nomogram, with vaginal birth as the outcome, was developed and evaluated by calibration curve and decision curve analyses. The pairwise association between maternal and fetal parameters and a prolonged first stage of labour was quantified. Results: Head circumference (HC), abdominal circumference (AC), intertuberous distance (ITD), interspinous diameter (ISD), and body mass index (BMI) were introduced to develop a nomogram with good diagnostic performance (area under the curve = 0.799, sensitivity = 83%, and specificity = 73%). The cephalopelvic index of diameter (CID) in 54 women with a prolonged first stage of labour was much smaller in those who delivered via cesarean section compared with those who delivered vaginally (18.09 \u00b1 1.14 vs. 21.29 \u00b1 1.06; p = 0.046). Conclusions: An MRI pelvimetry-based nomogram may predict the probability of vaginal delivery. Practitioners should reassess the pelvimetry parameters to decide whether the trial of labour should be continued if it is prolonged.<\/jats:p>","DOI":"10.3390\/jcm12020442","type":"journal-article","created":{"date-parts":[[2023,1,5]],"date-time":"2023-01-05T06:31:27Z","timestamp":1672900287000},"page":"442","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Predictive Value of MRI Pelvimetry in Vaginal Delivery and Its Practicability in Prolonged Labour\u2014A Prospective Cohort Study"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1459-5984","authenticated-orcid":false,"given":"Juan","family":"Li","sequence":"first","affiliation":[{"name":"Department of Obstetrics, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"},{"name":"Key Labouratory of Women\u2019s Reproductive Health of Zhejiang Province, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Lou","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"},{"name":"Key Labouratory of Women\u2019s Reproductive Health of Zhejiang Province, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weizeng","family":"Zheng","sequence":"additional","affiliation":[{"name":"Department of Radiology, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"},{"name":"Key Labouratory of Women\u2019s Reproductive Health of Zhejiang Province, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tian","family":"Dong","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"},{"name":"Key Labouratory of Women\u2019s Reproductive Health of Zhejiang Province, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengmeng","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"},{"name":"Key Labouratory of Women\u2019s Reproductive Health of Zhejiang Province, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9526-2278","authenticated-orcid":false,"given":"Baihui","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"},{"name":"Key Labouratory of Women\u2019s Reproductive Health of Zhejiang Province, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiong","family":"Luo","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"},{"name":"Key Labouratory of Women\u2019s Reproductive Health of Zhejiang Province, Women\u2019s Hospital, Zhejiang University School of Medicine, Hangzhou 310006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"219","DOI":"10.12659\/PJR.896380","article-title":"Pelvimetry by Three-Dimensional Computed Tomography in Non-Pregnant Multiparous Women Who Delivered Vaginally","volume":"81","author":"Salk","year":"2016","journal-title":"Pol.
