Berglund J, Liljeblad M, Baron T
Magn Reson Med
. 2024 May;
92(4):1484-1495.
PMID: 38725423
Purpose: To develop and evaluate a phase unwrapping method for cine phase contrast MRI based on graph cuts. Methods: A proposed Iterative Graph Cuts method was evaluated in 10 cardiac...

Magn Reson Imaging
. 2024 Apr;
110:35-42.
PMID: 38574981
Background: Paired cerebral blood flow (CBF) measurement is usually acquired before and after vasoactive stimulus to estimate cerebrovascular reserve (CVR). However, CVR may be confounded because of variations in time-to-maximum...

Correia de Verdier M, Berglund J, Wikstrom J
Eur Radiol Exp
. 2024 Mar;
8(1):45.
PMID: 38472565
Background: Phase-contrast magnetic resonance imaging (PC-MRI) quantifies blood flow and velocity noninvasively. Challenges arise in neurovascular disorders due to small vessels. We evaluated the impact of voxel size, number of...

Sprenger T, Kits A, Norbeck O, van Niekerk A, Berglund J, Ryden H, et al.
Magn Reson Med
. 2021 Dec;
87(5):2178-2193.
PMID: 34904751
Purpose: Implement a fast, motion-robust pulse sequence that acquires T -weighted, T -weighted, T -weighted, T fluid-attenuated inversion recovery, and DWI data in one run with only one prescription and...

Control of a wireless sensor using the pulse sequence for prospective motion correction in brain MRI
van Niekerk A, Berglund J, Sprenger T, Norbeck O, Avventi E, Ryden H, et al.
Magn Reson Med
. 2021 Aug;
87(2):1046-1061.
PMID: 34453458
Purpose: To synchronize and pass information between a wireless motion-tracking device and a pulse sequence and show how this can be used to implement customizable navigator interleaving schemes that are...

Berglund J, Sprenger T, van Niekerk A, Ryden H, Avventi E, Norbeck O, et al.
Magn Reson Med
. 2021 Jun;
86(4):1970-1982.
PMID: 34076922
Purpose: To enable SWI that is robust to severe head movement. Methods: Prospective motion correction using a markerless optical tracker was applied to all pulse sequences. Three-dimensional gradient-echo and 3D...

Magn Reson Med
. 2020 Oct;
85(3):1468-1480.
PMID: 33090529
Purpose: To describe a new method for encoding chemical shift using asymmetric readout waveforms that enables more SNR-efficient fat/water imaging. Methods: Chemical shift was encoded using asymmetric readout waveforms, rather...

. 2020 Sep;
85(3):1427-1440.
PMID: 32989859
Purpose: To enable motion-robust diffusion weighted imaging of the brain using well-established imaging techniques. Methods: An optical markerless tracking system was used to estimate and correct for rigid body motion...

Magn Reson Med
. 2020 Sep;
85(2):868-882.
PMID: 32871026
Purpose: The purpose of this work is to describe a T -weighted fluid-attenuated inversion recovery (FLAIR) sequence that is able to produce sharp magnetic resonance images even if the subject...
