Amniotic fluid volume (AFV) measured by maximum vertical pocket (MVP) or amniotic fluid index (AFI), is a key indicator of fetoplacental well-being and is assessed by ultrasound (US) after 20 weeks’ gestational age (GA). Fetal magnetic resonance imaging (MRI) is sometimes performed in isolation, and there is no standard assessment of AFV by MRI. Our purpose is to assess the robustness of US AFV indices and interrater variability by MRI in patients with known normal indices at same day US. Read More

T1-weighted imaging is a routine sequence in fetal MR imaging, which allows vicarious imaging of the fetal colon due to the short T1 signal characteristics of meconium. The purpose of this study was to compare image quality and acquisition time of a T1-mDixon sequence relative to a standard fast T1 gradient echo sequence, and to determine whether bowel pathology (such as colon hernaition in congenitial diaphragmatic hernia) can be more quickly and clearly delineated with T1-mDIXON.

Previous studies show that phase contrast MRI (PC-MRI) can successfully measure fetal blood flow in late gestation singleton fetuses. To date there is a paucity of data quantifying fetal blood flow of twin or early gestational age pregnancies (~19 weeks). Twin-twin transfusion syndrome (TTTS) is a rare complication of monochorionic pregnancies that is believed to result from inequal flow distribution between fetuses. In this novel investigation, we utilized PC-MRI to investigate fetal aortic flow in early gestational age fetuses with TTTS or selective Intrauterine Growth Restriction (sIUGR). We compared flow distribution between the smaller and larger fetus in each twin pair. Read More

Postmortem imaging is increasingly used following stillbirths and neonatal death. Estimating time of death has legal, biological, and ethical implications. This study aims to investigate feasibility of prenatal MRI in estimating time of death in intra-uterine fetal demise (IUFD). Read More

Both placental vascular density and oxygenation can indicate placenta health. MRA is a powerful tool to evaluate tissue vasculature but with limited applications because of the use of contrast agents. T₂* maps can be used to estimate the placental oxygen reserve. In this work, we acquired non-contrast enhanced MRA and T₂* maps to evaluate placental vasculature and oxygenation. Read More

The purpose of this study is to report visualization rates for standard cardiac axial views by FCMR using a prospective ECG pseudogating method and compare visualization rates for acquisitions performed in 1.5 and 3T. Secondary aims include a comparison of image quality between 2 observers and between 1.5 and 3T. Specific absorption rates (SAR) are also compared. Read More

Bladder exstrophy (BE), cloacal exstrophy (CE), and "Omphalocele, Exstrophy of the Cloaca, Imperforate Anus, and Spinal Defects Complex" (OEIS) are very rare conditions. They can present in isolation or as part of a spectrum of congenital malformations involving multiple organ systems. The diagnosis can be missed or misidentified during prenatal imaging due in no small part to the rarity and complexity of these conditions. The purpose of this study is to determine whether prenatal referral to specialty centers improves diagnostic accuracy, with the potential to improve patient counseling through a multidisciplinary approach.
