Esophageal atresia (EA) is a relatively rare congenital anomaly. Esophageal pouch (EP) is the only direct sign of EA on fetal MRI, but is not always seen. Distended hypopharynx (DHP) has been reported as a useful prenatal sign of EA, but as EP and DHP are both subjective assessments, the prenatal diagnosis of EA is challenging. The aim of this study was to evaluate whether quantitative measurement of distended pharynx is useful in the diagnosis of EA. Read More

Hypoxic Ischemic Encephalopathy (HIE) occurs in 1-6/1000 livebirths often leading to death or neurological disability. Neonatal brain magnetic resonance imaging (MRI) is used to assess severity of brain injury and provide prognostic information in the newborn period. However, 20-50% HIE patients do not have early abnormal MRI findings detected by qualitative neuroradiologic evaluation and yet have adverse outcomes evident by 2 years of age. Our aim was to investigate whether quantitative MRI analysis can find subtle abnormalities that help improve prognostication and reduce the incidence of falsely reassuring neonatal MRI among infants with HIE.

Synthetic magnetic resonance imaging (SyMRI) is a new imaging technique that permits generating multiple contrast-weighted images based on relaxivity measurements of tissue properties in a single acquisition using a multi-echo, multi-delay saturation recovery spin-echo sequence of approximately 6 minutes.

Anatomic changes during bone growth and skeletal maturation are under-studied and incompletely understood, partially attributed to the sparing use of ionizing radiation in children. Recently, a clinically-feasible UTE (ultra-short echo time) MRI technique has emerged, enabling the direct visualization of bone. Although validated in adults, its spatial resolution and reproducibility have not been fully investigated in children. Therefore, the purpose of this study is 1) to determine the feasibility of UTE MRI to quantify changes in vertebral porosity and disc hydration along the thoracolumbar spine and 2) to investigate inter-rater reproducibility.
