The article titled "Assessment of the time course of in utero post mortem foetal brain changes by diffusion-weighted imaging after radiofrequency ablation for foetal reduction in monochorionic pregnancies" by Behnaz Moradi et al., published in the Journal of Obstetrics and Gynaecology (2022 Aug;42(6):2542-2544), does not have an abstract available.

The study focuses on evaluating the progression of in utero post-mortem fetal brain alterations using diffusion-weighted imaging (DWI) following radiofrequency ablation (RFA) for fetal reduction in monochorionic pregnancies. The authors aimed to analyze the temporal changes in the fetal brain post-RFA to better understand the effects of this procedure on brain tissue integrity.

While the abstract is not provided, the title suggests that the research involves monitoring fetal brain changes over time using DWI, a magnetic resonance imaging technique sensitive to the diffusion of water molecules, which can reveal microstructural alterations in tissues. This approach is particularly relevant in assessing the impact of RFA, a procedure used to reduce the number of fetuses in complicated monochorionic pregnancies, on the remaining fetal brain tissue.
