Respiration Can Trigger Cerebrovascular Reactivity: A Novel Method to Quantify Cerebrovascular Resistance Dynamics Using Real‐Time Phase‐Contrast MRI

Magnetic Resonance in Medicine, EarlyView.
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.

Motion‐Compensated Diffusion Imaging With Phase‐Contrast for Robust Quantification of Regional Cerebral Blood Flow

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and evaluate a motion‐compensated diffusion imaging with phase‐contrast (MC‐DIP) technique for mitigating errors in regional cerebral blood flow (rCBF) quantification caused by physiological brain motion. Methods Diffusion‐weighted images were acquired in 11 healthy volunteers on a 3.0 T MRI system using three gradient ...

Low‐Cost and Detunable Wireless Resonator Glasses for Enhanced Eye MRI With Concurrent High‐Quality Whole‐Brain MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT PurposeTo develop a wearable wireless resonator glasses design that enhances eye MRI signal‐to‐noise ratio (SNR) without compromising whole‐brain image quality at 7 T. MethodsThe device integrates two detunable LC loop resonators into a lightweight, 3D‐printed frame positioned near the eyes.

Delayed Life‐Threatening Thyroid Artery Hemorrhage After Percutaneous Transesophageal Gastro‐Tubing in Amyotrophic Lateral Sclerosis: A Case Report

Neurology and Clinical Neuroscience, EarlyView.
ABSTRACT Percutaneous transesophageal gastro‐tubing provides enteral access when endoscopic gastrostomy is not feasible, but delayed vascular injury is seldom reported. We describe a 73‐year‐old woman with amyotrophic lateral sclerosis and prior gastrectomy who became ventilator‐dependent and underwent percutaneous transesophageal gastro‐tubing.
