The aim of the present study is to investigate the possible association of the presence and type\/location of placenta previa on MRI with PAS and maternal peripartum outcome. One hundred eighty-nine pregnant women (mean age: 35 years; mean gestational age: 32 weeks) at high risk for PAS underwent a dedicated placental MRI. All women underwent a C-section within 6 weeks from the MRI. All MRIs were evaluated by two experienced genitourinary radiologists for presence, type (complete\/partial vs. marginal\/low lying), and location (anterior vs. anterior-posterior vs. posterior) of placenta previa. Statistical analysis was performed for possible association of type\/location of previa with placental invasiveness and peripartum outcomes. Intraoperative information was used as a reference standard. Complete\/partial previa was detected in 143\/189 (75.6%) and marginal\/low lying previa in 33\/189 (17.5%) women; in 88\/189 (46.6%) women, the placenta had anterior\u2013posterior, in 54\/189 (28.6%) anterior and in 41\/189 (21.7%) posterior. Complete\/partial previa had an at least 3-fold probability of invasiveness and was more frequently associated with unfavorable peripartum events, including massive intraoperative blood loss or hysterectomy, compared to low-lying\/marginal placenta. Posterior placental location was significantly associated with lower rates of PAS and better clinical outcomes. In conclusion, the type and location of placenta previa shown with MRI seems to be associated with severity of complications during delivery and should be carefully studied.<\/jats:p>","DOI":"10.3390\/diagnostics14090925","type":"journal-article","created":{"date-parts":[[2024,5,2]],"date-time":"2024-05-02T11:39:42Z","timestamp":1714649982000},"page":"925","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["MRI Assessed Placental Location as a Diagnostic Tool of Placental Invasiveness and Maternal Peripartum Morbidity"],"prefix":"10.3390","volume":"14","author":[{"given":"Charis","family":"Bourgioti","sequence":"first","affiliation":[{"name":"First Department of Radiology, School of Medicine, National and Kapodistrian University of Athens, Aretaieion Hospital, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2678-0845","authenticated-orcid":false,"given":"Marianna","family":"Konidari","sequence":"additional","affiliation":[{"name":"First Department of Radiology, School of Medicine, National and Kapodistrian University of Athens, Aretaieion Hospital, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4967-2505","authenticated-orcid":false,"given":"Makarios","family":"Eleftheriades","sequence":"additional","affiliation":[{"name":"Second Department of Obstetrics and Gynaecology, School of Medicine, National and Kapodistrian University of Athens, Aretaieion Hospital, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8280-7796","authenticated-orcid":false,"given":"Marianna","family":"Theodora","sequence":"additional","affiliation":[{"name":"First Department of Gynaecology and Obstetrics, School of Medicine, National and Kapodistrian University of Athens, Alexandra Hospital, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Evangelia","family":"Nikolaidou","sequence":"additional","affiliation":[{"name":"Department of Gynaecology and Obstetrics, IASO Maternity Hospital, 15123 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Konstantina","family":"Zafeiropoulou","sequence":"additional","affiliation":[{"name":"First Department of Radiology, School of Medicine, National and Kapodistrian University of Athens, Aretaieion Hospital, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chara","family":"Tzavara","sequence":"additional","affiliation":[{"name":"Department of Health, Epidemiology and Medical Statistics School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stavros","family":"Fotopoulos","sequence":"additional","affiliation":[{"name":"Department of Gynaecology and Obstetrics, IASO Maternity Hospital, 15123 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7108-211X","authenticated-orcid":false,"given":"George","family":"Daskalakis","sequence":"additional","affiliation":[{"name":"First Department of Gynaecology and Obstetrics, School of Medicine, National and Kapodistrian University of Athens, Alexandra Hospital, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lia Angela","family":"Moulopoulos","sequence":"additional","affiliation":[{"name":"First Department of Radiology, School of Medicine, National and Kapodistrian University of Athens, Aretaieion Hospital, 11528 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"654","DOI":"10.1097\/AOG.0000000000001005","article-title":"Abnormal Placentation: Placenta Previa, Vasa Previa, and Placenta Accreta","volume":"126","author":"Silver","year":"2015","journal-title":"Obstet.
