Purpose: This study was done to evaluate the role of fetal magnetic resonance imaging (MRI) in the study of gastrointestinal malformations in comparison to prenatal ultrasound (US).
Materials And Methods: A prospective (2010-2012) study of 38 fetal MRI scans was performed on 38 fetuses between 24 and 38 weeks of gestation. All the fetuses had a US diagnosis of gastrointestinal anomalies. T2-weighted HASTE, T1-weighted fast gradient echo, TrueFISP and diffusion-weighted images of the fetal abdomen were obtained on a 1.5-Tesla magnet. All fetal MRI diagnoses were compared with postnatal US findings, autopsy or surgical reports.
Results: Fetal MRI was able to confirm the sonographic findings in nine of 38 fetuses (23.7%), to provide additional information in 23 of 38 fetuses (60.6%), to exclude the US diagnosis in five cases (5.2%) and to change it in two cases (5.2%). It was not able to characterize a case of gastric duplication and a case of abdominal cystic lymphangioma (5.2%).
Conclusions: Fetal MRI can be used as a complementary imaging modality to US in prenatal evaluation of gastrointestinal anomalies and can be considered a valuable tool not only for confirming or excluding but also for providing additional information to fetal ultrasonographic findings.

Various space occupying lesions can arise in the orbit, ranging from developmental anomalies to malignancies, and many of the diseases occurring in children are different from the pathologies in the adult population. As the clinical presentation is frequently nonspecific, radiologic evaluation is essential for lesion detection and characterization as well as patient management. While orbital masses may in some cases involve multiple compartments, a simple compartmental approach is the key for the diagnosis on imaging studies, and MRI is the modality of choice.

Holoprosencephaly (HPE) is a severe and complex congenital brain malformation caused by a defect in the midline cleavage of the prosencephalon during early embryonic development. It is the most common prosencephalic malformation in humans and is categorized into three classical forms based on the severity of this cleavage defect: alobar, semilobar, and lobar HPE. A milder interhemispheric variant, called syntelencephaly, is also considered a form of HPE.

In drug-resistant epilepsy, a visual inspection of intracranial electroencephalography (iEEG) signals is often needed to localize the epileptogenic zone (EZ) and guide neurosurgery. The visual assessment of iEEG time-frequency (TF) images is an alternative to signal inspection, but subtle variations may escape the human eye. Here, we propose a deep learning-based metric of visual complexity to interpret TF images extracted from iEEG data and aim to assess its ability to identify the EZ in the brain.

Objectives: Planning the mode of delivery of a full-term breech singleton remains a challenging task. The aim of this work is to compare the neonatal and maternal short-term outcomes after planned vaginal delivery and caesarean section and to evaluate the influence of an MRI pelvimetry on the short-term outcomes in order to provide appropriate advice to pregnant women with breech presentation.
Methods: This is a retrospective monocentric analysis of all deliveries with singleton pregnancies from breech presentation >36 + 0 weeks of gestation between 08/2021 and 09/2023.

Introduction: Type 1 congenital pulmonary airway malformation (CPAM) is characterized by large, dilated cysts that rapidly expand due to aeration immediately after birth, often necessitating surgical resection. In atypical cases of CPAM type 1, fetal T2-weighted magnetic resonance imaging (MRI) reveals a low-intensity solid lung mass containing multiple irregular T2 high-intensity areas.
Methods: Data were retrospectively collected for infants with atypical CPAM type 1 born at our hospital between March 2002 and December 2022.
