Magnetic resonance imaging and spectroscopic techniques are widely used in humans both
for clinical diagnostic applications and in basic research areas such as cognitive …

Abstract Functional MRI (fMRI) at 7 T and above provides improved Signal-to-Noise Ratio
and Contrast-to-Noise Ratio compared to 3 T acquisitions. In addition to the beneficial …

Magnetic resonance spectroscopy (MRS) and spectroscopic imaging (MRSI) allow the
chemical analysis of physiological processes in vivo and provide powerful tools in the life …

Attention-deficit hyperactive disorder (ADHD) is characterized by inattention and increased
impulsive and hypermotoric behaviors. Despite the high prevalence and impact of ADHD …

In magnetic resonance imaging (MRI), spatial field gradients are applied along each axis to
encode the location of the nuclear spin in the frequency domain. During recent years, the …

Purpose Magnetic field fluctuations caused by subject motion, such as breathing or limb
motion, can degrade image quality in brain MRI, especially at high field strengths. The …

Long echo time (TE) MR spectroscopy (MRS) sequences are sensitive only to metabolites of
low molecular weight. At shorter TE, significantly more metabolite signals are detectable …

The full potential of magnetic resonance spectroscopic imaging (MRSI) is often limited by
localization artifacts, motion-related artifacts, scanner instabilities, and long measurement …

Purpose MR imaging and spectroscopy require a highly stable, uniform background field.
The field stability is typically limited by hardware imperfections, external perturbations, or …

An efficient multi-slice inversion–recovery EPI (MS-IR-EPI) sequence for fast, high spatial
resolution, quantitative T 1 map** is presented, using a segmented simultaneous multi …
