Mesoscale Whole‐Brain T2*‐Weighted and Associated Quantitative MRI in Humans at 10.5 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To demonstrate mesoscale whole‐brain T2*‐weighted (T2*w) MRI at 10.5 T, quantify R2* relaxation rate and magnetic susceptibility (χ), and evaluate T2*w contrast at such high field strength. Methods Multi‐echo GRE (ME‐GRE) data were collected in healthy adults at 0.5 mm isotropic resolution at 10.5 T.

Design of Differential Single‐Block and Multi‐Block Presaturated Ultrashort Echo Time Pulse Sequences for Fast and Flexible Short‐T2 Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultrashort echo time (UTE) techniques are essential for the magnetic resonance imaging of short‐T2 signals. Current UTE techniques are time‐consuming and often require the acquisition of an inflexible volume. In this work, we implement new UTE sequences—differential single‐block presaturated UTE (δSB‐UTE) and differential multi‐block ...

Enhanced Quantitative Phosphocreatine MR Imaging of Skeletal Muscle Using a Global–Local Two‐Branch Deep Learning Model

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Phosphocreatine (PCr) is an essential marker of muscle metabolism, and accurate quantification of its (fs) and its exchange rate (ksw) is essential for diagnosing various muscular and neuromuscular diseases. Although chemical exchange saturation transfer (CEST) MRI can detect the saturation transfer effect from PCr, quantification of ...

An Interchangeability Test Method for Developing IPG Impedance Equivalency Evidence for Cardiac Implantable Electronic Device Under MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Patients with cardiac implantable electronic devices (CIEDs) may receive replacement device components over time, resulting in mixed‐manufacturer systems that pose unknown, potentially higher risk under MRI exposure. It is not clear how to efficiently evaluate whether adding a non‐original implantable pulse generator (IPG) changes the ...
