MRI Assessed Placental Location as a Diagnostic Tool of Placental Invasiveness and Maternal Peripartum Morbidity.

Placenta accreta spectrum (PAS) disorder is one of the leading causes of peripartum maternal morbidity and mortality; its early identification during pregnancy is of utmost importance to ensure the optimal clinical outcome. 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.

Comparison between 1.5-T and 3.0-T MRI for the diagnosis of placenta accreta spectrum disorders.

Purpose: Accurate antenatal diagnosis of placenta accreta spectrum (PAS) is important for optimal management. The purpose of this study was to compare the respective capabilities of 1.5-T and 3.

Intraplacental Fetal Vessel Diameter May Help Predict for Placental Invasiveness in Pregnant Women at High Risk for Placenta Accreta Spectrum Disorders.

Background Prenatal identification of placenta accreta spectrum (PAS) disorder is essential for treatment planning. More objective means for predicting PAS and clinical outcome may be provided by MRI descriptors. Purpose To investigate the association of intraplacental fetal vessel (IFV) diameter at MRI with PAS and peripartum complications.

Stripped fetal vessel sign: a novel pathological feature of abnormal fetal vasculature in placenta accreta spectrum disorders with MRI correlates.

Abnormal intraplacental hypervascularity is a well-known MRI feature of Placenta Accreta Spectrum (PAS), but the precise nature of these vessels has not yet been specified. Histopathological examination of eleven PAS-hysterectomy specimens and subsequent review of the corresponding MRIs, revealed the presence of large fetal vascular trunks extending deep towards the placental periphery and demonstrating deficient branching along their course ('stripped-fetal-vessel' sign). To our knowledge, this is the first report to describe the pattern of abnormal fetal vasculature in correlation with MRI in PAS.

MRI prognosticators for adverse maternal and neonatal clinical outcome in patients at high risk for placenta accreta spectrum (PAS) disorders.

Background: Placenta accreta spectrum (PAS) disorders may be associated with significant mortality and morbidity for both mother and fetus.

Purpose/hypothesis: To identify MRI risk factors for poor peripartum outcome in gravid patients at risk for PAS.

Study Type: Prospective.

MRI Features Predictive of Invasive Placenta With Extrauterine Spread in High-Risk Gravid Patients: A Prospective Evaluation.

Objective: The objective of our study was to evaluate MRI diagnostic ability in predicting invasive placenta with extrauterine spread in high-risk gravid patients.

Subjects And Methods: Between March 2016 and June 2017, 49 patients (mean age, 35.7 years; mean gestational age, 32.
