Quantifying Dehydration Effects of Porcine Vocal Fold Attenuation With Optical Coherence Tomography
The purpose of this study is to use optical coherence tomography (OCT) to characterize the effect of dehydration on the optical attenuation coefficient of porcine vocal fold (VF) tissue. The optical attenuation coefficient tissue decreased linearly with dehydration, dropping by approximately 0.08 mm−1 for every 1% increase in mass loss.

ABSTRACT Purpose To directly quantify respiration‐driven cerebrovascular resistance dynamics (CRD) using a gas‐free MRI framework based on the internal‐to‐external artery carotid flow ratio (ratio_Q). Theory and Methods Two independent datasets (n = 10 and n = 17) were used to evaluate repeatability and to compare breathing conditions.

Dynamic Mode Decomposition (DMD) for Low‐Latency Real‐Time Cardiac MRI
ABSTRACT Purpose To demonstrate dynamic mode decomposition (DMD) for high spatiotemporal low‐latency online reconstruction in 2D real‐time cardiac MRI. Methods DMD was applied to 2D spiral balanced steady state free precession (bSSFP) real‐time adult and fetal cardiac MRI at 0.55 T, with data from 10 healthy adult volunteers (3F/7M; age: 21–49; BMI: 20–

5D Flow MRI Reveals Respiration‐Driven Changes in Blood Flow Energetics in Congenital Heart Disease
ABSTRACT Purpose Hemodynamic monitoring is essential for patients with right‐sided congenital heart disease (CHD). Respiration may have an increased impact on pulmonary flow in these patients that cannot be assessed by standard tools including 4D flow MRI. This study uses 5D flow MRI to assess respiratory‐cycle variations in flow energetics in patients

Nerve Ultrasound Detects Peripheral Nerve Enlargement in Cerebrotendinous Xanthomatosis
ABSTRACT Introduction/Aims Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder caused by variants in the CYP27A1 gene, resulting in cholestanol accumulation in various tissues, including peripheral nerves. Polyneuropathy is common but often under‐recognized in CTX.

ABSTRACT In utero interventions are transformative in addressing genetic and anatomic conditions during fetal development. Next generation sequencing enables early genetic testing, playing a pivotal role in prenatal decision‐making by supporting risk stratification, precise and timely diagnosis, which directly informs eligibility for fetal surgical and
