Spectro-Dynamic MRI: Characterizing Mechanical Systems on a Millisecond Scale

Autor: Max H. C. van Riel, Niek R. F. Huttinga, Alessandro Sbrizzi

Publikováno v: IEEE Access, Vol 10, Pp 271-285 (2022)

Measuring in vivo dynamics can yield valuable information for studying the functioning of the cardiovascular or the musculoskeletal system and for the diagnosis of related diseases. MRI is a powerful medical imaging modality, but it shows severe limi

Brain and Head-and-Neck MRI in Immobilization Mask: A Practical Solution for MR-Only Radiotherapy

Autor: Stefano Mandija, Federico D'Agata, Robin J. M. Navest, Alessandro Sbrizzi, Rob H. N. Tijssen, Marielle E. P. Philippens, Cornelis P. J. Raaijmakers, Enrica Seravalli, Joost J. C. Verhoeff, Jan J. W. Lagendijk, Cornelis A. T. van den Berg

Publikováno v: Frontiers in Oncology, Vol 9 (2019)

In brain/head-and-neck radiotherapy (RT), thermoplastic immobilization masks guarantee reproducible patient positioning in treatment position between MRI, CT, and irradiation. Since immobilization masks do not fit in the diagnostic MR head/head-and-n

Water content-based electrical properties tomography: results from a retrospective clinical study

Autor: Stefano Mandija, Sarah M. Jacobs, Jordi P.D. Kleinloog, Hongyan Liu, Oscar van der Heide, Anja G. Kolk, Alessandro Sbrizzi, Cornelis A.T. van den Berg

Tissue electrical properties (EPs: conductivity and relative permittivity) maps can be reconstructed from water content maps using an empirical model calibrated by fitting literature water content to literature EPs values (wEPT). Results on phantoms

Efficient performance analysis and optimization of transient-state sequences for multiparametric magnetic resonance imaging

Autor: Miha Fuderer, Oscar van der Heide, Hongyan Liu, Cornelis A. T. van den Berg, Alessandro Sbrizzi

Publikováno v: NMR in biomedicineREFERENCES.

In transient-state multiparametric MRI sequences such as Magnetic Resonance Spin TomogrAphy in Time-domain (MR-STAT), MR fingerprinting, or hybrid-state imaging, the flip angle pattern of the RF excitation varies over the sequence. This gives conside

Gaussian Processes for real-time 3D motion and uncertainty estimation during MR-guided radiotherapy

Autor: Niek R.F. Huttinga, Tom Bruijnen, Cornelis A.T. van den Berg, Alessandro Sbrizzi

Respiratory motion during radiotherapy causes uncertainty in the tumor's location, which is typically addressed by an increased radiation area and a decreased dose. As a result, the treatments' efficacy is reduced. The recently proposed hybrid MR-lin

Nonrigid 3D motion estimation at high temporal resolution from prospectively undersampled k‐space data using low‐rank MR‐MOTUS

Autor: Tom Bruijnen, Niek R. F. Huttinga, Alessandro Sbrizzi, Cornelis A. T. van den Berg

Publikováno v: Magnetic Resonance in Medicine

Purpose With the recent introduction of the MR‐LINAC, an MR‐scanner combined with a radiotherapy LINAC, MR‐based motion estimation has become of increasing interest to (retrospectively) characterize tumor and organs‐at‐risk motion during ra

Conditional safety margins for less conservative peak local SAR assessment: A probabilistic approach

Autor: Bart R. Steensma, Alexander J.E. Raaijmakers, Peter R. Luijten, Ettore F. Meliadò, Cornelis A. T. van den Berg, Alessandro Sbrizzi

Publikováno v: Magnetic Resonance in Medicine

PURPOSE The introduction of a linear safety factor to address peak local specific absorption rate (pSAR10g ) uncertainties (eg, intersubject variation, modeling inaccuracies) bears one considerable drawback: It often results in over-conservative scan

Acceleration Strategies for MR-STAT: Achieving High-Resolution Reconstructions on a Desktop PC within 3 minutes

Autor: Hongyan Liu, Oscar van der Heide, Stefano Mandija, Cornelis A. T. van den Berg, Alessandro Sbrizzi

MR-STAT is an emerging quantitative magnetic resonance imaging technique which aims at obtaining multi-parametric tissue parameter maps from single short scans. It describes the relationship between the spatial-domain tissue parameters and the time-d
