Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Image‐Derived Volumetry During Forced Expiration Using a 3D Fermat Looped, Orthogonally Encoded Trajectory

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2698-2707, December 2026.
ABSTRACT Purpose To enable MRI‐based nongated 3D depiction of forced expiration with both high spatio‐temporal resolution and fidelity of lung dynamics. Methods An undersampled 3D Fermat looped, orthogonally encoded trajectory (FLORET) was optimized for nonsegmented dynamic acquisitions during forced expiration and a corresponding model‐based ...

Correlating Pulmonary Hemodynamics With HP 129Xe Dissolved‐Phase MRSI in a Controlled Porcine Intervention Study

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2588-2600, December 2026.
ABSTRACT Purpose Pulmonary hypertension is related to a 1‐year mortality ranging from < 5% to > 20% in low‐ and high‐risk groups. Right heart catheterization is the diagnostic gold standard, associated with a 1.1% rate of severe adverse events, posing the need for a non‐invasive diagnostic tool.

Incomplete Spoiling Correction for 3D T1$$ {T}_1 $$ Mapping

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2848-2856, December 2026.
ABSTRACT Purpose Assess the impact of incomplete spoiling and spatial saturation on T1$$ {T}_1 $$ mapping using the variable flip angle (VFA) spoiled gradient recalled echo sequence (SPGR). Develop a correction for incomplete spoiling that results in an accurate estimate of T1$$ {T}_1 $$, essential for quantitative MRI applications.

Cardiovascular Autonomic Neuropathy in Charcot–Marie–Tooth Disease: A Genotype‐Stratified Study of PMP22 Duplication and GJB1 Mutation Carriers

Journal of the Peripheral Nervous System, Volume 31, Issue 4, December 2026.
ABSTRACT Background and Aims Data on cardiovascular autonomic neuropathy (CAN) are sparse in Charcot–Marie–Tooth disease. We aimed to determine the prevalence of CAN in CMT1A and CMTX1 and its associations with neuropathy severity and heart rate variability (HRV), compared with age‐ and sex‐matched controls. Methods Thirty‐six CMT1A, 24 CMTX1 patients,

Feasibility and SNR Performance of Hyperpolarized 129Xe Gas Exchange Imaging Using a Balanced SSFP Sequence

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2201-2212, November 2026.
ABSTRACT Purpose To develop a balanced SSFP (bSSFP) sequence for pulmonary 129Xe dissolved‐phase imaging based on a previously described double‐echo sequence facilitating separation into red blood cell and membrane signals, to test its feasibility and compare its SNR performance and imaging results to an analogous FLASH sequence.
