Magnetic resonance imaging (MRI) of the human spinal cord at 7T has been demonstrated
by a handful of research sites worldwide, and the spinal cord remains one of the areas in …

Magnetic resonance imaging (MRI) has been driven toward ultrahigh magnetic fields (UHF)
in order to benefit from correspondingly higher signal-to-noise ratio and spectral resolution …

Arrays of radiofrequency coils are widely used in magnetic resonance imaging to achieve
high signal-to-noise ratios and flexible volume coverage, to accelerate scans using parallel …

Purpose MRI at ultra‐high fields in the human body is highly challenging and requires
lengthy calibration times to compensate for spatially heterogeneous profiles. This study …

Parallel transmission (pTX) techniques are required to tackle a number of challenges, eg,
the inhomogeneous distribution of the transmit field and elevated specific absorption rate …

Three‐dimensional (3D) human heart imaging at ultra‐high fields is highly challenging due
to respiratory and cardiac motion‐induced artifacts as well as spatially heterogeneous …

Purpose To research and evaluate the performance of broadband tailored kT‐point pulses
(TP) and universal pulses (UP) for homogeneous excitation of the human heart at 7T …

Purpose To obtain homogeneous signal throughout the human liver at 7 T. Flip angle (FA)
