The purpose of this study was to compare brain metabolite concentrations between healthy and CHD neonates before and after cardiac surgery. Healthy term newborns and neonates with CHD were recruited prospectively. T-weighted brain images and MRS data were acquired in the cerebellum, right frontal lobe and basal ganglia.

Transcranial ultrasound localization microscopy (t-ULM) is faced with challenges posed by the skull, including acoustic attenuation and phase aberrations. There is a significant request for an efficient aberration correction method achieving a great balance between computational complexity and accuracy. In this study, the ray theory is first applied to in-vivo transcranial imaging to calculate the traveltime table in the inhomogeneous medium model of the imaging region.

Purpose: The liver-brain axis regulates metabolic homeostasis, with glucose metabolism playing a key role. Liver dysfunction, such as fibrosis, may impact brain metabolism and consequently, brain function. Positron emission tomography (PET) imaging provides a non-invasive approach to study glucose metabolism in both organs.

This study presents a medico-legal case study of an infant who died as a result of intestinal volvulus, a rare but severe complication secondary to the ingestion of multiple magnets and button batteries. The mutual attraction of magnets through adjacent intestinal loops, compounded by the corrosive effects of button batteries, can precipitate rapid and irreversible damage to the gastrointestinal wall. A comprehensive review of the literature on documented pediatric cases involving the ingestion of magnets and button batteries was undertaken to compare the spectrum and frequency of complications.

Purpose: To analyze macular microvascular networks and investigate correlations between visual acuity and quantitative parameters in patients with Leber's hereditary optic neuropathy (LHON) using optical coherence tomography angiography (OCTA).
Methods: An observational, cross-sectional study was conducted, including 25 eyes from 25 genetically confirmed chronic LHON patients and 25 eyes from 25 age-matched healthy controls. Images were obtained using a spectral domain OCTA system.
