Summary: This study used MRI to compare brain volumes of discordant twins and found that twins with appropriate birth weight had smaller brain structure volumes compared to those with lower birth weight. However, there was no significant difference in neurodevelopmental outcomes between discordant twins.

Summary: The study found that fetuses with complex congenital heart disease (CHD) have altered cerebral metabolites, particularly in the third trimester of pregnancy. These alterations are associated with survival to hospital discharge and warrant further study on the long-term neurodevelopmental consequences.

Summary: The study included 64 foetuses with cortical formation abnormalities (CFA) who underwent two in utero magnetic resonance (iuMR) exams, with 62% showing consistent CFA description between the two studies. In 38% of cases, there was a category change, including cases without CFA initially detected, changes in laterality/symmetry, and re-classification within the same group. Brain abnormalities other than CFA were present in around half of the cases on both first and second studies. Prognosis was predicted to have changed in 8% of cases based on the second study, with all indicating a worse prognosis.

Summary: The objective of this study was to investigate the image quality and capability of GRAPPA accelerated 3D SWI for the whole spine. The results showed that 3D-SWI is feasible for improved visualization of the whole fetal vertebral column with adequate image quality and high accuracy, providing a supplementary method to conventional MR imaging.

Summary: There has been a growing demand for medical imaging in pregnant women over the last few decades, but it is challenging due to the involvement of both the mother and the fetus, leading to various medical, ethical, and legal considerations. In practice, concerns over fetal safety often result in unnecessary avoidance of useful diagnostic tests, particularly those involving ionizing radiation. This review article focuses on safety guidelines and considerations for using different imaging modalities in pregnant women, as well as imaging work-ups for common medical conditions with an emphasis on fetal and maternal safety.

Summary: This study aimed to develop an MRI-based scoring system for postmortem fetal brain maceration and correlate it with autopsy results. The brain-specific maceration score showed a strong correlation with fetal brain maceration seen at histopathological exam, and different observers were able to reproduce the score reliably.

Summary: This study aimed to develop deep learning models to predict biological brain age using multimodal imaging data. The results showed that combining T1-weighted and angiography MRI data significantly improved prediction accuracy, while also identifying the most contributing brain regions and arteries.

Summary: The increasing number of women in the perimenopausal phase due to global population ageing highlights the importance of studying the perimenopausal brain. Magnetic resonance imaging (MRI) has been widely used to reveal brain alterations associated with perimenopausal symptoms. This review collects literature on perimenopausal brain using MRI techniques, describes the changes in brain structure, function, perfusion, and metabolic compounds, and provides a perspective on future multi-modal MRI studies in the perimenopausal brain. Further research is needed to address the neural heterogeneity in the perimenopausal brain for precise diagnosis and personalized treatment of perimenopausal symptoms.

Summary: This study investigated T2-based and diffusion-weighted imaging (DWI) measurements for evaluating fetal brain maturation during the last trimester of pregnancy. The frontal T2/thalamus ratio emerged as a potential additional biomarker of fetal brain maturation.

Summary: The study evaluated the incidence of unexpected findings in both the mother and fetus during antenatal MRI examinations, finding that incidental findings are common during antenatal MRIs. Therefore, appropriate counseling for women and establishing robust follow-up and management protocols are essential before imaging.

Summary: Currently, endovascular therapy (EVT) is widely used for large vessel occlusion in acute ischemic stroke patients, but the occurrence of post-EVT intracerebral hemorrhage still leads to disability in more than half of EVT-treated patients. Predicting this complication is important for personalized treatment strategies and selecting suitable candidates for clinical trials. Brain and vascular imaging biomarkers show promise in providing insights into acute stroke pathophysiology and predicting post-EVT intracerebral hemorrhage. This review summarizes the current literature on the role of cerebrovascular imaging biomarkers in predicting this complication to guide future observational or therapeutic studies.
