Three of the ten women who were correctly diagnosed as having placenta previa had scans that could easily have been misinterpreted as normal. Because a false\u2010negative diagnosis of placenta previa is clinically much more serious than a false\u2010positive diagnosis, these cases are elaborated upon. Recognition of a laterally positioned placenta previa and observation of blood in the region of the internal cervical os should minimize false\u2010negative diagnostic errors.<\/jats:p>","DOI":"10.1002\/jcu.1870090303","type":"journal-article","created":{"date-parts":[[2007,2,28]],"date-time":"2007-02-28T01:37:10Z","timestamp":1172626630000},"page":"109-113","source":"Crossref","is-referenced-by-count":17,"title":["Placenta previa: Avoiding false\u2010negative diagnoses"],"prefix":"10.1002","volume":"9","author":[{"given":"Faye C.","family":"Laing","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,12]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1148\/128.1.177"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1259\/0007-1285-46-544-255"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(70)90274-7"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(79)90680-X"},{"key":"e_1_2_1_6_2","first-page":"707","article-title":"Ultrasonic diagnosis of placenta previa","volume":"42","author":"Scheer K","year":"1973","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1148\/109.1.167"},{"key":"e_1_2_1_8_2","first-page":"706","article-title":"Second trimester placenta previa","volume":"50","author":"Wexler P","year":"1977","journal-title":"Obstet Gynecol"},{"key":"e_1_2_1_9_2","first-page":"538","article-title":"Ultrasonic placentography: A new method for placental localization","volume":"96","author":"Gottesfeld KR","year":"1966","journal-title":"Am J Obstet Gynecol"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1259\/0007-1285-49-587-940"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1148\/131.2.465"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1148\/128.1.255"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1148\/128.1.183"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.1870060119"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1148\/128.1.169"},{"key":"e_1_2_1_16_2","first-page":"745","volume-title":"Textbook of Gynecology and Obstetrics","author":"Wingate MB","year":"1975"},{"key":"e_1_2_1_17_2","first-page":"378","volume-title":"Textbook of Obstetrics and Gynecology","author":"Goplerud CP","year":"1977"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(69)90659-0"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.1870080106"}],"container-title":["Journal of Clinical Ultrasound"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fjcu.1870090303","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jcu.1870090303","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,12]],"date-time":"2023-11-12T05:34:07Z","timestamp":1699767247000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jcu.1870090303"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1981,3]]},"references-count":18,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1981,3]]}},"alternative-id":["10.1002\/jcu.1870090303"],"URL":"https:\/\/doi.org\/10.1002\/jcu.1870090303","archive":["Portico"],"relation":{},"ISSN":["0091-2751","1097-0096"],"issn-type":[{"value":"0091-2751","type":"print"},{"value":"1097-0096","type":"electronic"}],"subject":[],"published":{"date-parts":[[1981,3]]}}}
