DynaTOF: Time‐Resolved Noncontrast Cerebral MR Angiography Using Spatially Modulated RF Saturation

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a time‐resolved extension of three‐dimensional time‐of‐flight MR angiography, termed Dynamic TOF (DynaTOF), that exploits intrinsic RF saturation behavior to enable noncontrast visualization of cerebrovascular hemodynamics.

5D Flow MRI Reveals Respiration‐Driven Changes in Blood Flow Energetics in Congenital Heart Disease

open access: yesMagnetic Resonance in Medicine, EarlyView.
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

Single‐Shot 2D Radial Echo Planar Imaging for Functional MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a novel single‐shot radial echo planar imaging (ss‐rEPI) technique for rapid, distortion‐free brain imaging in functional MRI experiments. Methods Radial multi‐gradient echo (radial mGRE) data were acquired on a 3T clinical scanner using a 2D ss‐rEPI readout with small golden‐angle rotations between echoes.

SimulScan and Partial Least Squares: Visualizing Swallowing Through Functional and Dynamic Imaging Correlations

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Swallowing involves the precise coordination of muscles and brain areas and can be disrupted in a variety of neurological conditions. Current methods to visualize swallowing cannot examine both the biomechanics and brain activity associated with specific swallowing events.

Myasthenia Gravis and Thymoma

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Thymoma is the most common tumor of the anterior mediastinum. Approximately 20%–30% of patients with a thymoma develop myasthenia gravis (MG), and an additional one third may possess positive acetylcholine receptor (AChR) antibodies without MG.
