Discrete Fourier transform (DFT) implementation requires high computational resources and
time; a computational complexity of order O (N 2) for a signal of size N. Fast Fourier …

Over more than 30 years in vivo MR spectroscopic imaging (MRSI) has undergone an
enormous evolution from theoretical concepts in the early 1980s to the robust imaging …

Magnetic resonance imaging (MRI) evaluation of the developing brain has dramatically
increased over the last decade. Faster acquisitions and the development of advanced MRI …

Gamma-aminobutyric acid (GABA) and glutamate (Glu) are the major neurotransmitters in
the brain. They are crucial for the functioning of healthy brain and their alteration is a major …

Long acquisition times due to intrinsically low signal‐to‐noise ratio and the need for highly
homogeneous B0 field make MRS particularly susceptible to motion or scanner instability …

Objectives Noninvasive, affordable, and reliable mapping of brain glucose metabolism is of
critical interest for clinical research and routine application as metabolic impairment is linked …

MRSI in the brain at≥ 7 T is a technique of great promise, but has been limited mainly by
low B 0/B 1+-homogeneity, specific absorption rate restrictions, long measurement times …

Magnetic resonance spectroscopy (MRS) provides unique information about the
neurobiological substrates of brain function in health and disease. However, many of the …

Magnetic resonance signals from different nuclei can be excited or received at the same
time, rendering simultaneous or rapidly interleaved multi‐nuclear acquisitions feasible. The …

Introduction Converging evidence suggests that ketamine elicits antidepressant effects via
enhanced neuroplasticity precipitated by a surge of glutamate and modulation of GABA …
