tDCS induced GABA change is associated with the simulated electric field in M1, an effect mediated by grey matter volume in the MRS voxel (2022)
Journal Article
Nandi, T., Puonti, O., Clarke, W. T., Nettekoven, C., Barron, H. C., Kolasinski, J., …Stagg, C. J. (2022). tDCS induced GABA change is associated with the simulated electric field in M1, an effect mediated by grey matter volume in the MRS voxel. Brain Stimulation, 15(5), 1153-1162. https://doi.org/10.1016/j.brs.2022.07.049

BACKGROUND AND OBJECTIVE: Transcranial direct current stimulation (tDCS) has wide ranging applications in neuro-behavioural and physiological research, and in neurological rehabilitation. However, it is currently limited by substantial inter-subject...

Connectivity-Guided Theta Burst Transcranial Magnetic Stimulation Versus Repetitive Transcranial Magnetic Stimulation for Treatment-Resistant Moderate to Severe Depression: Magnetic Resonance Imaging Protocol and SARS-CoV-2–Induced Changes for a Randomized Double-blind Controlled Trial (2022)
Journal Article
Pszczolkowski, S., Cottam, W. J., Briley, P. M., Iwabuchi, S. J., Kaylor-Hughes, C., Shalabi, A., …Morriss, R. (2022). Connectivity-Guided Theta Burst Transcranial Magnetic Stimulation Versus Repetitive Transcranial Magnetic Stimulation for Treatment-Resistant Moderate to Severe Depression: Magnetic Resonance Imaging Protocol and SARS-CoV-2–Induced Changes for a Randomized Double-blind Controlled Trial. JMIR Research Protocols, 11(1), Article e31925. https://doi.org/10.2196/31925

Background: Depression is a substantial health and economic burden. In approximately one-third of patients, depression is resistant to first-line treatment; therefore, it is essential to find alternative treatments. Transcranial magnetic stimulation...

Estimation and removal of spurious echo artifacts in single‐voxel MRS using sensitivity encoding (2021)
Journal Article
Berrington, A., Považan, M., & Barker, P. B. (2021). Estimation and removal of spurious echo artifacts in single‐voxel MRS using sensitivity encoding. Magnetic Resonance in Medicine, 86(5), 2339-2352. https://doi.org/10.1002/mrm.28848

Purpose

In localized MRS, spurious echo artifacts commonly occur when unsuppressed signal outside the volume of interest is excited and refocused. In the spectral domain, these signals often overlap with metabolite resonances and hinder accurate q...

Calibration-free regional RF shims for MRS (2021)
Journal Article
Berrington, A., Považan, M., Mirfin, C., Bawden, S., Park, Y. W., Marsh, D. C., …Gowland, P. A. (2021). Calibration-free regional RF shims for MRS. Magnetic Resonance in Medicine, 86(2), 611-624. https://doi.org/10.1002/mrm.28749

Purpose: Achieving a desired RF transmit field (B1+) in small regions-of-interest (ROIs) is critical for single-voxel MR spectroscopy at ultra-high field. RF shimming, using parallel transmission, requires B1+ mapping and optimisation, which limits i... Read More about Calibration-free regional RF shims for MRS.
