1.
PRFS-based MR thermometry versus an alternative T1 magnitude method--comparative performance predicting thermally induced necrosis in hepatic tumor ablation
Rosenberg C, Kickhefel A, Mensel B, Pickartz T, Puls R, Roland J, et al.
PLoS One . 2013 Nov; 8(10):e78559. PMID: 24205260
Objective: To compare the accuracy of a semi-quantitative proton resonance frequency shift (PRFS) thermal mapping interface and an alternative qualitative T1 thermometry model in predicting tissue necrosis in an established...

ARFI-prepared MRgHIFU in liver: simultaneous mapping of ARFI-displacement and temperature elevation, using a fast GRE-EPI sequence
Auboiroux V, Viallon M, Roland J, Hyacinthe J, Petrusca L, Morel D, et al.
Magn Reson Med . 2012 Jan; 68(3):932-46. PMID: 22246646
MR acoustic radiation force imaging (ARFI) is an elegant adjunct to MR-guided high intensity focused ultrasound for treatment planning and optimization, permitting in situ assessment of the focusing and targeting...

Reference-free PRFS MR-thermometry using near-harmonic 2-D reconstruction of the background phase
Salomir R, Viallon M, Kickhefel A, Roland J, Morel D, Petrusca L, et al.
IEEE Trans Med Imaging . 2011 Sep; 31(2):287-301. PMID: 21937345
Proton resonance frequency shift (PRFS) MR thermometry (MRT) is the generally preferred method for monitoring thermal ablation, typically implemented with gradient-echo (GRE) sequences. Standard PRFS MRT is based on the...

Correction of susceptibility-induced GRE phase shift for accurate PRFS thermometry proximal to cryoablation iceball
Kickhefel A, Weiss C, Roland J, Gross P, Schick F, Salomir R
MAGMA . 2011 Sep; 25(1):23-31. PMID: 21898135
Introduction: The susceptibility contrast between frozen and unfrozen tissue disturbs the local magnetic field in the proximity of the ice-ball during cryotherapy. This effect should be corrected for in real...
5.
Clinical evaluation of MR temperature monitoring of laser-induced thermotherapy in human liver using the proton-resonance-frequency method and predictive models of cell death
Kickhefel A, Rosenberg C, Weiss C, Rempp H, Roland J, Schick F, et al.
J Magn Reson Imaging . 2011 May; 33(3):704-12. PMID: 21563256
Purpose: To assess the feasibility, precision, and accuracy of real-time temperature mapping (TMap) during laser-induced thermotherapy (LITT) for clinical practice in patients liver with a gradient echo (GRE) sequence using...
6.
Observation and correction of transient cavitation-induced PRFS thermometry artifacts during radiofrequency ablation, using simultaneous ultrasound/MR imaging
Viallon M, Terraz S, Roland J, Dumont E, Becker C, Salomir R
Med Phys . 2010 May; 37(4):1491-506. PMID: 20443470
Purpose: MR thermometry based on the proton resonance frequency shift (PRFS) is the most commonly used method for the monitoring of thermal therapies. As the chemical shift of water protons...

Validation of fast MR thermometry at 1.5 T with gradient-echo echo planar imaging sequences: phantom and clinical feasibility studies
Cernicanu A, Lepetit-Coiffe M, Roland J, Becker C, Terraz S
NMR Biomed . 2008 Jun; 21(8):849-58. PMID: 18574794
The purpose of this work was to validate in phantom studies and demonstrate the clinical feasibility of MR proton resonance frequency thermometry at 1.5 T with segmented gradient-echo echo planar...
