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

Congenital anomalies causing lower extremity shortening can result from dysgenesis or agenesis of the bones of the thigh, leg or foot; they are generally a very uncommon occurrence, with an incidence on the order of one case per 1,000,000 to one case per 100,000 births. These conditions result in varying degrees of morbidity, ranging from gait dysfunction to complete lack of the ability to ambulate. The accurate characterization of such an anomaly may be challenging prenatally, but can have significant impact on prognosis and treatment planning.
We present a collection of cases depicting the spectrum of prenatally diagnosed anomalies of limb development, including proximal focal femoral deficiency, multiple cases of varying degrees of fibular and tibial hemimelia, amniotic band syndrome, benign uterine packing, neurofibromatosis, clubfoot anomaly and rocker bottom foot, all of which were evaluated on prenatal ultrasound and/or fetal MRI.
Accurate prenatal diagnosis is extremely important for prognosis, treatment planning and risk-stratification for associated congenital anomalies. The purpose of this poster will be to highlight the imaging features by both fetal MRI and prenatal US, discuss potential diagnostic pitfalls and review the clinical implications of this interesting spectrum of congenital disorders. We will describe a methodical approach to assessment of these patients. Our recommendations include: prenatal US to include a complete set of bilateral long bone and foot length measurements; lateral and footprint views of the fetal foot; views of both tibiae and fibulae bilaterally; views of the spine and upper extremities, a thorough search for other abnormalities; fetal MRI for complex cases or when US findings are limited; and a complete family and maternal history, including notation of family stature.
Examples of the classic appearance of these conditions will be presented. Several missed diagnoses and the lessons learned will also be discussed. Counseling points addressed by the orthopedic surgeon will be included. Outcome management will be reviewed. Read More

Atretic cephalocele is a rare type of neural tube defect that occurs in the parietal or occipital scalp. Most cases present postnatally with a scalp nodule which may also have associated skin and hair abnormalities. We will present a case of atretic cephalocele diagnosed with fetal MRI as well as two additional cases of postnatally diagnosed atretic cephalocele in different patients.

A 26 week gestational age male fetus was found to have ventriculomegaly on routine OB ultrasound and was referred to maternal fetal medicine. Further ultrasound imaging demonstrated features suspicious for a posterior fossa encephalocele. A fetal MRI was then performed which demonstrated imaging findings consistent with an atretic cephalocele.

The imaging findings associated with atretic cephalocele including embryologic positioning of the straight sinus, the “spinning top” appearance of the tentorial incisura, and the “cigar shaped” CSF tract in the interhemispheric fissure will be illustrated in the exhibit using both fetal and postnatal MRI. Although the exact embryological development of atretic cephaloceles is not completely understood, the proposed mechanisms will be discussed. A brief summary of the associated syndromes and clinical outcomes reported in the literature will be presented.

Atretic cephalocele is a rare condition that is usually diagnosed postnatally with several characteristic imaging findings. These same abnormalities can also be seen on fetal MRI which can lead to an earlier diagnosis and more appropriate family counseling. Read More

The purpose of this case series is to describe the variable prenatal presentation of lethal and nonlethal hypophosphatasia, obstetrical outcomes, and postnatal course of the nonlethal cases.

5 genetically proven cases of hypophosphatasia were evaluated in our fetal imaging center from 2009 to 2016 and initially imaged between 17 weeks and 34 weeks gestation. The prenatal imaging, prenatal testing, pregnancy outcome, and postnatal or autopsy imaging and genetic testing are reviewed in this case series.

All 5 cases were referred with a high suspicion of a skeletal dysplasia. Fetal sonography demonstrated a spectrum of bowing, shortening, and acute fractures of the long bones, variable involvement of the upper and lower extremities, and axial skeleton involvement.
Of the 5 cases, 3 were nonlethal. Postnatal imaging in these cases was concordant with the prenatal assessment of variable mild limb shortening and bowing and without involvement of the axial skeleton.
Case 4 was terminated at 20 weeks due to severe micromelia and irregular long bones with postmortem radiographs demonstrating shortening and fractures with severe demineralization of the skull.
Case 5, first evaluated at 29 weeks gestation demonstrated severe bowing and shortening of the long bones, a small chest circumference with beading of the ribs. Postnatal radiographs demonstrated spurs in the midshafts of the fibula and ulna with severely demineralized skull. The infant died in the immediate postnatal period. Read More

Fetal demise (FD) occurs in 1/1000 pregnancies after 20 weeks gestation. MRI is increasingly being used after ultrasound to assess fetal pathology. FD may occur in the interval between ultrasound and MRI, and various organ systems have been described as having changes on fetal MRI. Although ultrasound findings of FD have been well described, criteria for FD on MRI have not. Diffusion MRI evaluates Na⁺/K⁺ channel viability and can be used to evaluate tissue death. Flowing blood produces signal loss on MRI, and along with fetal heart activity results in MRI signal loss of the cardiac chambers. FD with no heart motion and increased signal within non-flowing blood in the heart should result in increased signal in the chambers relative to the myocardium. Either of these findings can be seen with different fetal pathology, but the combination of brain and cardiac changes may allow for a diagnosis of FD. We hypothesize that restricted brain diffusion in certain brain lobes along with increased signal within heart chambers is specific for FD. Read More

Fetal intracranial volume is one of the most important parameters used in assessing normal fetal growth. Based on volumetric ultrasound (US), Virtual Organ Computer-Aided-anaLysis (VOCAL^TM) is a commonly used technique for such measurement. Magnetic resonance imaging (MRI) offers better soft tissue contrast for fetal brain imaging and is considered as one of the best tools for tissue volumetry, and as a standard for comparison. In this work we compare fetal intracranial volumes measured from MRI with those obtained from VOCAL^TM measurements in the same fetuses. Read More

As an inexpensive modality that does not require ionizing radiation, ultrasound is the preferred method for screening for fetal anomalies. When an abnormality is detected on ultrasound, the limitations of the modality often elicit further evaluation with MRI, as MRI can provide more detail and information to the radiologist and clinician. Chest and cardiac pathologies are among the most common findings on prenatal ultrasound and often warrant additional imaging. Consequently, an understanding of these findings and how they appear on different modalities is essential to the pediatric imager.
This electronic exhibit features fetal ultrasound and MRI of mediastinal lymphangioma, type I-III congenital pulmonary airway malformations, intralobar, extralobar, and subdiaphragmatic sequestrations, left and right sided congenital diaphragmatic hernias, hypoplastic left heart, heterotaxy, AV canal defect, and rhabdomyoma. In addition to reviewing the correlation of findings on ultrasound and MRI, prognosis as well as conditions and syndromes commonly associated with these chest and cardiac anomalies will be examined.
The goal of this exhibit is to provide an overview of common fetal cardiopulmonary abnormalities on different, complementary imaging modalities. Familiarity with these conditions is necessary for the radiologist to provide critical information to clinicians to allow prompt intervention in the postnatal period. These findings can additionally serve as an indication to the radiologist to search for associated findings, allowing prognostication and appropriate counseling of parents. Read More

Case Presentation
A 27-year-old female patient, primigravida, with no pathological clinical history, and a low risk first-trimester screening for aneuploidy and preeclampsia. Morphological ultrasound was performed at 21 weeks of gestational age, revealing a cystic structure at the lumbosacral spine with bone alteration. Myelomeningocele was suspected, but no associated Chiari type II anomaly was observed. Additional Fetal Magnetic Resonance Imaging (Fetal MRI) was requested.

Findings
At 24 weeks, an obstetric ultrasound was made identifying a cystic image at the lumbosacral level with the absence of a placode. An osseous spur protruding into the medullary canal was observed, dividing the medullary cone in two. Suspicious fatty tissue suggestive of a lipoma was also noted. Fetal MRI confirmed the ultrasound findings, consistent with diastematomyelia (DM) associated with closed meningocele, lipoma, and medullary canal ectasia.

Discussion
Dysraphism are congenital malformations of the spinal canal, with a prevalence of 1 to 3 per 1000 live births, and the lumbosacral spine being the most commonly affected site.
DM is a closed-type dysraphia in which there is a splitting of the spinal cord into two halves separated by a fibrous, cartilaginous, or bony septum. Clinical manifestations are variable and are typically related to orthopedic problems, urinary or fecal incontinence, and characteristic cutaneous abnormalities.
When isolated, DM tends to have a favorable prognosis, but approximately one-third of affected patients have an accompanying dysraphism. Current recommendations include early postnatal surgery to prevent further complications.

Conclusion
DM is a rare disorder of spinal development that can be diagnosed prenatally through imaging. Precise identification of the lesion and the exclusion of other associated structural malformations are crucial for prognosis. Read More

Stillbirth is a sad complication of pregnancy. Establishing the cause of death in intrauterine fetal demise (IUFD) is important to bring psychological closure to the family and crucial for reproductive counseling. The gold standard to establish the cause of IUFD is perinatal autopsy. However, perinatal autopsy rates are falling worldwide, largely attributed to patients and physicians discomfort with death and discussion of postmortem examinations as well as social and religious reasons. There is a lack of experience with minimally invasive perinatal autopsy in the United States and even more limited publications in the subject. Our main goal was to investigate the added value of postmortem MRI to conventional autopsy in the clinical setting. Our program has had successes and failures, of which learning opportunities exist for other institutions that desire to implement similar programs. This paper will discuss the timeline of our progress and share examples of potential roadblocks and keys to success in implementing such a program. Read More

Esophageal atresia (EA) is a relatively rare congenital anomaly. Esophageal pouch (EP) is the only direct sign of EA on fetal MRI, but is not always seen. Distended hypopharynx (DHP) has been reported as a useful prenatal sign of EA, but as EP and DHP are both subjective assessments, the prenatal diagnosis of EA is challenging. The aim of this study was to evaluate whether quantitative measurement of distended pharynx is useful in the diagnosis of EA. Read More

Magnetic Resonance Imaging is a powerful tool for the detection of ferromagnetic components. This property can be used for the early detection of pathologic conditions related to liver iron overload. Neonatal hemochromatosis and hemosiderosis are conditions associated with severe liver disease. Infections like parvovirus and cytomegalovirus, metabolic conditions and gestational allo-immune liver disease can produce neonatal hemochromatosis phenotype.
Fetal iron overload can be detected early by using T₂* multi-echo gradient sequence.

Fetal lung maturity is a key factor determining perinatal morbidity and mortality. Clinicians can perform amniocentesis and evaluate the amniotic fluid for certain surfactant byproducts such as lethicin, sphingomyelin, and phosphatidylglycerol to assess lung maturity. However, amniocentesis is invasive, and its results can be prone to errors. Imaging can offer a reliable non-invasive alternative that can be used for prognostication as well as suggestion of further follow up. Ultrasound is the imaging modality of choice to assess fetal development. It is readily available on widespread scale to assess for various abnormalities that can occur during pregnancy. Parameters used to assess fetal lung maturity on ultrasound include lung to head ratio as well as the observed/expected lung to head ratio. However, ultrasound parameters can be subjective, have inter- and intra-observer variability and depend highly on the imaging technique and quality. The advent of ultrafast MRI sequences expanded its use in fetal imaging offering an alternative to ultrasound. It is generally used as a problem-solving tool due its excellent soft tissue resolution. Two parameters are gaining acceptance as means to assess fetal lung development on MRI: lung volume measurements and lung/liver signal intensity ratio. Our exhibit aims at familiarizing pediatric radiologists with parameters used to assess lung development on both ultrasound and MRI. Read More
