A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.

Blind Estimation Versus Direct Measurement of the Arterial Input Function in Dynamic Contrast‐Enhanced MRI of the Breast

Magnetic Resonance in Medicine, EarlyView.
Purpose Accurate arterial input functions (AIFs) are essential for quantitative dynamic contrast‐enhanced (DCE) MRI, yet direct measurement is challenging and population‐averaged AIFs neglect patient‐specific variability. Blind deconvolution provides an alternative by estimating patient‐specific AIFs directly from tissue data, up to a scale factor ...

A Sub‐Microsecond Switch Enabling SWIFT 23Na Imaging at 10.5 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To enable sodium SWIFT imaging, which is a zero‐echo time imaging technique, at ultra‐high magnetic fields through the development of custom electronics hardware, and to showcase this capability with in vivo imaging results. Methods The custom hardware developed consists of a high‐speed optical trigger with 10 ns resolution, an in‐bore

Short Echo‐Time Spiral MRSI Versus Single‐Voxel Spectroscopy in the Human Brain at 3 Tesla With Semi‐LASER Localization

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Magnetic resonance spectroscopy techniques are widely used to non‐invasively study brain metabolism. Despite advances in magnetic resonance spectroscopic imaging (MRSI), there is a notable absence of research on comparing fast non‐Cartesian MRSI with single‐voxel spectroscopy (SVS), limiting our understanding of its performance and ...

Simultaneous T2, T2*, and R2′ Mapping for Multiple Sclerosis Using Nonlinear Model‐Based Reconstruction of Undersampled Radial RARE‐EPI MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To demonstrate the synergy of undersampled radial 2in1‐RARE‐EPI acquisition and nonlinear model‐based reconstruction for accelerated and simultaneous T2, T2*, and R2′ mapping in brains of patients with multiple sclerosis (MS). Methods 2in1‐RARE‐EPI combines a RARE module with an EPI module to capture T2 and T2* information.
