“…Based on this MRI semiology, the small intestine was considered normal when the loops had a subjectively satisfactory quantity in the abdomen and normal diameter for the GA, with physiological fluid in the lumen with T2 signal hyperintensity. On the other hand, it was considered abnormal when the remaining bowel was collapsed, without T2 high signal filling but with either T2 hypointense or isointense contents in the lumen [15].…”

Objective: Bowel obstructions beyond the duodenum represent a heterogeneous group of congenital anomalies with a highly variable prognosis, the main issue being postnatal short bowel syndrome (SBS). The objective of our study was to evaluate the contributions of fetal MRI in cases of bowel obstruction. Materials and Methods: A retrospective analysis of all newborns, for whom both ante-natal ultrasound and fetal MRI were available, referred to our center for suspected bowel obstruction was performed. Examinations were reviewed blinded to the postnatal outcome. Key outcome measures included exact diagnosis and the existence of postoperative SBS. We evaluated the contribution of MRI in determining precise location and etiology of the bowel obstruction, dilatation of the proximal bowel loops, and assessment of the quality of the remaining distal bowel loops. Results: Twenty-five newborns were included. There were 19 single obstructions and 6 complex forms (4 apple peel syndromes and 2 multiple atresias). MRI correctly identified the affected segment of the small bowel in 59.1% of the cases. MRI identified the mechanism of obstruction in 72% of cases. MRI reliably predicted an abnormal appearance of the bowel distal to the obstruction in 100% of the severe cases (3/3) and in 66.7% of complex forms (4/6). Conclusion: Our study suggests that fetal MRI, when done in addition to prenatal ultrasound, is contributory in the management of fetuses with suspected bowel obstruction. MRI may be particularly useful in determining the location and origin of the bowel obstruction and in assessing the quality of the bowel distal to the obstruction, which might assist in the prediction of SBS and more detailed prenatal counseling.

“…Other emerging MRI techniques, such as magnetic sensitive mapping and phase imaging, are expected to help characterize the microstructure of the developing white matter ( 59 , 60 ). In the digestive system, MRI allows for the visualization of the extent and pattern of dilated bowel loops ( 61 ). In the skeletal musculoskeletal system, the length and morphology of the ossified bone can be assessed, and three-dimensional imaging can provide a comprehensive assessment of fetal bone morphology.…”

BackgroundThe development of prenatal diagnosis technology allows prompt detection of severe fetal diseases. To address adverse factors that threaten fetal survival, fetal therapy came into existence, which aims to preserve the function after birth to a higher degree and improve the quality of life.ObjectiveTo conduct a comprehensive bibliometric analysis of studies on fetal therapy in the past decade and explore the research trends and hotspots in this field.MethodsWe conducted a systematic search on the Web of Science Core Collection to retrieve studies related to fetal therapy published from 2012 to 2022. VOSviewer and CiteSpace were used to analyze the key features of studies, including annual output, countries/regions, institutions, authors, references, research hotspots, and frontiers.ResultsA total of 9,715 articles were included after eliminating duplicates. The annual distribution of the number of articles showed that the number of articles published in fetal therapy had increased in the past decade. Countries and institutions showed that fetal therapy is more mature in the United States. Author analysis showed the core investigators in the field. Keyword analysis showed the clustering and emergence frequency, which helped summarize the research results and frontier hotspots in this field. The cocited references were sorted out to determine the literature with a high ranking of fetal therapy in recent years, and the research trend in recent years was analyzed.ConclusionsThis study reveals that countries, institutions, and researchers should promote wider cooperation and establish multicenter research cooperation in fetal therapy research. Moreover, fetal therapy has been gradually explored from traditional surgical treatment to gene therapy and stem cell therapy. In recent years, fetoscopic laser surgery, guideline, and magnetic resonance imaging have become the research hotspots in the field.

“…Fetal MRI can be used to determine the level of congenital gastric outlet obstructions. 10 MRI can also differentiate duodenal atresia from other causes of fetal gastric outlet obstruction, such as enteric duplication cyst and pyloric atresia. Considering that the classical ultrasound findings in gastric obstructions (polyhydramnios, etc) occur in the third trimester, it seems unlikely that pregnant women will undergo MRI for pyloric scanning.…”

Objectives In this study, we hypothesized that the pyloric sphincter can be directly visualized by ultrasonography in the prenatal period. Methods This study was designed as a cross‐section. Single, healthy pregnancies between 18 and 22 weeks of gestation who applied to the Perinatology outpatient clinic for second‐level ultrasonography were included in the study. In addition to the demographic characteristics of the participants, fetal pyloric mucosa, fetal pyloric sphincter length, and fetal pyloric sphincter thickness were measured by ultrasonography. Intrarater variability was calculated. Results A total of 93 eligible patients were evaluated in the study. The mean age of the participants was 27.25 ± 6.23, and the gestational age was 21.18 ± 0.98. Pylorus imaging and measurements were possible in all fetuses that were in the optimal position. Mean pyloric sphincter length (mm) was 5.32 ± 0.93, pyloric sphincter thickness (mm) was 2.13 ± 0.44, and sphincter muscle thickness (mm) was 1.05 ± 0.24. Conclusions The pyloric sphincter can be easily visualized on a second‐trimester ultrasound scan when the appropriate technique is used. This may make an additional contribution to the diagnosis of fetal gastrointestinal tract pathologies.
