(Journal article; Peer reviewed, 2020)Background: The hardware and software differences between MR vendors and individual sites influence the quantification of MR spectroscopy data. An analysis of a large data set may help to better understand sources of the ... -
Comparison of seven modelling algorithms for γ-aminobutyric acid–edited proton magnetic resonance spectroscopy
Craven, Alexander R.; Bhattacharyya, Pallab K.; Clarke, William T.; Dydak, Ulrike; Edden, Richard A.E.; Ersland, Lars; Mandal, Pravat K.; Mikkelsen, Mark; Murdoch, James B.; Near, Jamie; Rideaux, Reuben; Shukla, Deepika; Wang, Min; Wilson, Martin; Zöllner, Helge J.; Hugdahl, Kenneth Jan; Oeltzschner, Georg (Journal article; Peer reviewed, 2022)Edited MRS sequences are widely used for studying γ-aminobutyric acid (GABA) in the human brain. Several algorithms are available for modelling these data, deriving metabolite concentration estimates through peak fitting ... -

Frequency drift in MR spectroscopy at 3T
Hui, Steve C.N.; Mikkelsen, Mark; Zöllner, Helge J.; Craig-Craven, Alexander Richard; Ersland, Lars; Edden, Richard A.E. (Journal article; Peer reviewed, 2021)Purpose Heating of gradient coils and passive shim components is a common cause of instability in the B0 field, especially when gradient intensive sequences are used. The aim of the study was to set a benchmark for typical ...
