First In Vivo 23Na Human Imaging at 10.5 T Using a Combined Sodium‐Proton Transceiver Body Array

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To demonstrate the first in vivo human 23Na MRI at 10.5 T using a novel dual‐tuned transceiver body array and to evaluate a self‐gating approach for respiratory motion compensation, focusing on renal imaging. Methods A custom‐built eight‐channel 23Na‐loop 1H‐dipole transceiver array was designed, constructed, and characterized.

RF‐Shielding of Laser‐Cut Venous Stents: Calculations, Simulations, and Experiments

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop an analytical model of the RF‐shielding of laser‐cut venous stents for different orientations and stent geometries. Methods Laser‐cut venous stents are modeled as a grid composed of circular and rectangular loops. As these loops are orthogonal they shield different components of the transmit RF field.

A Novel 9‐Channel 1H, 3‐Channel 31P Radiofrequency Coil for Interleaved Multinuclear Studies of Human Calf Muscle at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a double‐tuned calf coil with excellent 1H and 31P performance to study muscle physiology by interleaved 1H/31P MRS and parallel imaging at 7 T. Methods The coil combines three 1H transceive dipoles, six 1H receive‐only loops and three 31P transceive loops, arranged in a nested, half‐cylindrical layout.

Field Strength‐Dependent White Matter R1 and R2 Anisotropy of Phase‐Cycled Balanced Steady‐State Free Precession Relaxometry

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate how the relaxation rates (R1, R2) and asymmetry indices (AI), derived from phase‐cycled balanced steady‐state free precession (pc‐bSSFP) data, depend on the orientation of white matter (WM) fiber tracts at different field strengths.
