Clinical characteristics did not differ between groups with normal or abnormal Doppler values; however, among normal Doppler results, SGA pregnancies demonstrated poorer fundal growth (<jats:italic>P<\/jats:italic>=0.006). Significant associations existed between abnormal Doppler results and asymmetric growth, inappropriately advanced placental maturation, and reduced liquor volume (all <jats:italic>P<\/jats:italic>\u22640.04), but with very low sensitivities (3.9%, 4.8%, and 14.5%, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Maternal characteristics and imaging variables did not reliably identify more than one\u2010third of pregnancies with evidence of suboptimal placentation.<\/jats:p><\/jats:sec>","DOI":"10.1016\/j.ijgo.2016.03.038","type":"journal-article","created":{"date-parts":[[2016,7,16]],"date-time":"2016-07-16T18:08:12Z","timestamp":1468692492000},"page":"38-42","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":8,"title":["Placental insufficiency among high\u2010risk pregnancies with a normal umbilical artery resistance index after 32 weeks"],"prefix":"10.1002","volume":"135","author":[{"given":"Lut","family":"Geerts","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elrike","family":"Van der Merwe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anneke","family":"Theron","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kerry","family":"Rademan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2016,12,2]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/ajo.12264"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.7196\/SAMJ.5019"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2458-11-S3-S1"},{"key":"e_1_2_6_5_2","first-page":"CD007529","article-title":"Fetal and umbilical Doppler ultrasound in high\u2010risk pregnancies","volume":"1","author":"Alfirevic Z.","year":"2010","journal-title":"Cochrane Database Syst Rev"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.0960-7692.2001.00590.x"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1080\/14767050601134926"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/uog.6249"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/uog.5377"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/uog.14706"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.2002.00652.x"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/AOG.0b013e31820b0884"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1002\/uog.14818"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2011.03.010"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.7196\/SAMJ.3812"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.placenta.2013.09.018"},{"key":"e_1_2_6_17_2","first-page":"CD007113","article-title":"Regimens of fetal surveillance for impaired fetal growth","volume":"6","author":"Grivell R.M.","year":"2012","journal-title":"Cochrane Database Syst Rev"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.150.2.6691115"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(79)90312-0"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1002\/pd.1868"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1002\/uog.5315"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1067\/mob.2002.127310"},{"key":"e_1_2_6_23_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1994.04010034.x"},{"key":"e_1_2_6_24_2","doi-asserted-by":"publisher","DOI":"10.1002\/uog.4019"},{"issue":"12","key":"e_1_2_6_25_2","first-page":"1289","article-title":"A centile chart for birth weight for an urban population of the Western Cape","volume":"85","author":"Theron G.B.","year":"1995","journal-title":"S Afr Med J"},{"key":"e_1_2_6_26_2","doi-asserted-by":"publisher","DOI":"10.1002\/uog.7738"},{"key":"e_1_2_6_27_2","doi-asserted-by":"publisher","DOI":"10.7196\/SAMJ.6751"}],"container-title":["International Journal of Gynecology &amp;
