This article reviews the most commonly used modern sequences designed to confront the two major challenges of in vivo magnetic resonance spectroscopy (MRS): spatial localization and metabolic specificity. The purpose of this review article is to provide a deeper and clearer understanding of the underlying mechanisms by which all modern MRS sequences operate. A descriptive explanation, consistent pulse sequence diagram, and theoretical concepts of the measured signal are given for five spatial…

Motion correction in magnetic resonance spectroscopy

Prospective and retrospective methods available in the literature can attenuate or eliminate most motion‐related artifacts and facilitate the acquisition of high‐quality data in the clinical research setting.

Broadband selective excitation radiofrequency pulses for optimized localization in vivo

New excitation RF pulses with the same B1 requirements but larger excitation bandwidth are shown to significantly reduce localization artifacts and to minimize chemical shift artifacts of metabolic compounds with spins in the amide area at 3T.

Hippocampal single‐voxel MR spectroscopy with a long echo time at 3 T using semi‐LASER sequence

Hippocampal long‐TE sLASER single voxel spectroscopy can provide macromolecule‐independent assessment of all major metabolites including Glx and m‐Ins, and investigates the feasibility of reproducibly measuring their concentrations at a long TE of 120 ms using a semi‐adiabatic localization by adiabatic selective refocusing (sLASer) sequence.

Quantifying the Metabolic Signature of Multiple Sclerosis by in vivo Proton Magnetic Resonance Spectroscopy: Current Challenges and Future Outlook in the Translation From Proton Signal to Diagnostic Biomarker

The existing findings of in vivo 1H-MRS on central nervous system metabolic abnormalities in multiple sclerosis and its subtypes are reviewed within the context of study design, spectral acquisition and processing, and metabolite quantification and an outlook on technical considerations is offered.

UTE-SPECIAL for 3D Localization at an Echo Time of 4 ms on a Clinical 3 Tesla Scanner

A novel sequence, referred to as Ultrashort echo TimE, SPin ECho, full Intensity Acquired Localized (UTE-SPECIAL), is described which is able to achieve ultrashorts echo times (4 ms) on a standard clinical 3T MR system while recovering the entirety of the available magnetization.

ORYX-MRSI: A Fully-Automated Open-Source Software for Three-Dimensional Proton Magnetic Resonance Spectroscopic Imaging Data Analysis

A MATLAB-based open-source data analysis software for 3D 1D 1H-MRSI, called Oryx-M RSI, which includes modules for visualization of raw 1h- MRSI data and LCModel outputs, chemical shift correction, tissue fraction calculation, metabolite map production, and registration onto standard MNI152 brain atlas while providing automatic spectral quality control, is presented.

Terminology and concepts for the characterization of in vivo MR spectroscopy methods and MR spectra: Background and experts' consensus recommendations

This work covers terms used to describe all aspects of MRS, starting from the description of the MR signal and its theoretical basis to acquisition methods, processing and to quantification procedures, as well as terms involved in describing results, including those used with regard to aspects of quality, reproducibility or indications of error.

Osprey: Open-source processing, reconstruction & estimation of magnetic resonance spectroscopy data

Osprey is the first MRS software to combine uniform pre-processing, linear-combination modelling, tissue correction and quantification into a coherent ecosystem, and compared to existing compiled, often closed-source modelling software, Osprey’s open-source code philosophy allows researchers to integrate state-of-the-art data processing and modelling routines, and potentially converge towards standardization of analysis.

Whole‐brain high‐resolution metabolite mapping with 3D compressed‐sensing SENSE low‐rank 1H FID‐MRSI

The successful combination of the 3D 1H-FID-MRSI with a constrained reconstruction to realize the detailed mapping of metabolite concentrations at high-resolution over the whole brain, and with an acquisition time that is compatible with clinical or research settings is demonstrated.

A novel approach to probing in vivo metabolite relaxation: Linear quantification of spatially modulated magnetization

A novel technique is proposed—multiple flip angle pulse‐driven ratio of longitudinal steady states (MARzss)—for preparing magnetization with T2/T1 weighting and is TE independent; T2, diffusion, and J‐coupling effects induced by the readout sequence are cancelled.

In vivo 1H NMR spectroscopy of rat brain at 1 ms echo time

Using optimized, asymmetric radiofrequency (RF) pulses for slice selection, the authors demonstrate that stimulated echo acquisition mode (STEAM) localization with ultra‐short echo time (1 ms) is possible, resulting in highly resolved in vivo 1H nuclear magnetic resonance spectra.

In vivo 1H NMR spectroscopy of the human brain at 7 T

In vivo 1H NMR spectra from the human brain were measured at 7 T to minimize J‐modulation and signal attenuation caused by the shorter T2 of metabolites and the ability to resolve overlapping multiplets of J‐coupled spin systems, such as glutamine and glutamate, was substantially increased.
