Echo planar correlated spectroscopic imaging: Implementation and pilot evaluation in human calf in vivo [PDF]

Magnetic Resonance in Medicine, 2010
AbstractExploiting the speed benefits of echo‐planar imaging (EPI), the echo‐planar spectroscopic imaging (EPSI) sequence facilitates recording of one spectral and two to three spatial dimensions faster than the conventional magnetic resonance spectroscopic imaging (MRSI).

Single-shot diffusion trace spectroscopic imaging using radial echo planar trajectories. [PDF]

Magn Reson Med
We present the first demonstration of single shot diffusion trace spectroscopic imaging using radial echo planar k-space trajectories on a clinical 3T scanner. Conventional DW-MRS requires three separate acquisitions to compute the trace apparent diffusion coefficient (ADC), whereas the single shot technique generates a trace-weighted signal in one ...

Comparison of high-resolution echo-planar spectroscopic imaging with conventional MR imaging of prostate tumors in mice

NMR in Biomedicine, 2005
AbstractHigh spectral and spatial resolution (HiSS) MRI of rodent tumors has previously been performed using conventional spectroscopic imaging to obtain images with improved contrast and anatomic detail. The work described here evaluates the use of much faster echo‐planar spectroscopic imaging (EPSI) to acquire HiSS data from rodent tumor models of ...

The Distribution of Major Brain Metabolites in Normal Adults: Short Echo Time Whole-Brain MR Spectroscopic Imaging Findings

Metabolites, 2022
This prospective study aimed to evaluate the variation in magnetic resonance spectroscopic imaging (MRSI)-observed brain metabolite concentrations according to anatomical location, sex, and age, and the relationships among regional metabolite ...

Brain temperature as an indicator of neuroinflammation induced by typhoid vaccine: Assessment using whole-brain magnetic resonance spectroscopy in a randomised crossover study

NeuroImage: Clinical, 2022
Prior studies indicate a pathogenic role of neuroinflammation in psychiatric disorders; however, there are no accepted methods that can reliably measure low-level neuroinflammation non-invasively in these individuals.

Spectroscopic MRI-Guided Proton Therapy in Non-Enhancing Pediatric High-Grade Glioma

Tomography, 2023
Radiation therapy (RT) is a critical part of definitive therapy for pediatric high-grade glioma (pHGG). RT is designed to treat residual tumor defined on conventional MRI (cMRI), though pHGG lesions may be ill-characterized on standard imaging ...

Lactate discrimination incorporated into echo‐planar spectroscopic imaging [PDF]

Magnetic Resonance in Medicine, 2001
AbstractA technique for discriminating a lactate signal from overlapping lipid signals in 1H spectroscopic imaging is presented. It is based on J‐coupling between lactate protons and on the broad spectral bandwidth of lipid signal. Measurement parameters used in the technique are determined so that TE is separated from n/J (n: a natural number, J: J ...
