Diamond-Based Nanoscale Quantum Relaxometry for Sensing Free Radical Production in Cells
Mayeul Sylvain Chipaux, Hoda Shirzad
Diamond magnetometry makes use of fluorescent defects in diamonds to convert magnetic resonance signals into fluorescence. Because optical photons can be detected much more sensitively, this technique currently holds several sensitivity world records for r ...
WILEY-V C H VERLAG GMBH20223-Dimensional Fluid and White Matter Suppression Magnetic Resonance Imaging Sequence Accelerated With Compressed Sensing Improves Multiple Sclerosis Cervical Spinal Cord Lesion Detection Compared With Standard 2-Dimensional Imaging
Objectives Fluid and white matter suppression (FLAWS) is a recently proposed magnetic resonance sequence derived from magnetization-prepared 2 rapid acquisition gradient-echo providing 2 coregistered datasets with white matter- and cerebrospinal fluid-supp ...
LIPPINCOTT WILLIAMS & WILKINS2022Real-time shimming with FID navigators
Purpose: To implement a method for real-time field control using rapid FID navigator (FIDnav) measurements and evaluate the efficacy of the proposed approach for mitigating dynamic field perturbations and improving T-2*-weighted image quality. Methods: FID ...
WILEY2022Quantitative Microstructural Imaging for Clinical Use
Today, Magnetic Resonance Imaging (MRI) is a well-established medical imaging modality thanks to its excellent soft tissue contrast. Conventional MR image contrasts can be weighted towards one or more physical properties that discriminate different tissues ...
EPFL2021Simultaneous 3D acquisition of H-1 MRF and Na-23 MRI
Purpose To develop a 3D MR technique to simultaneously acquire proton multiparametric maps (T-1, T-2, and proton density) and sodium density weighted images over the whole brain. Methods We implemented a 3D stack-of-stars MR pulse sequence which consists o ...
WILEY2021Fat navigators based retrospective motion correction strategies for brain magnetic resonance imaging
Magnetic resonance resonance (MRI) is a widely used modality to obtain in vivo tissue information.
Clinical applications are near countless, and almost all body parts can be examined using an MR
scanner. As the method is non invasive, does not use ionizing ...
EPFL20203-Dimensional magnetic resonance imaging of the freely moving human eye
Jérôme Yerly, Lorenzo Di Sopra, Josefina Adriana Maria Bastiaansen, João Pedro Forjaco Jorge, Silvio Ionta, Benedetta Franceschiello, David Zeugin
Eye motion is a major confound for magnetic resonance imaging (MRI) in neuroscience or ophthalmology. Currently, solutions toward eye stabilisation include participants fixating or administration of paralytics/anaesthetics. We developed a novel MRI protoco ...
PERGAMON-ELSEVIER SCIENCE LTD2020Development and Optimization of Methods for Accelerated Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) has yielded great success as a medical imaging modality in the past decades, and its excellent soft tissue contrast is used in clinical routine to support diagnosis today. However, MRI is still facing challenges. For exampl ...
EPFL2018Microwave Imaging of Brain Stroke
Brain stroke is an age-related illness which has become a major issue in our ageing societies. Early diagnosis and treatment are of high importance for the full recovery of the patient, as reminded in Anglo-Saxon countries by the abbreviation FAST (Face, A ...
EPFL2018Multimodal microstructure imaging: joint T2-relaxometry and diffusometry to estimate myelin, intracellular, extracellular, and cerebrospinal fluid properties
Jean-Philippe Thiran, Erick Jorge Canales Rodriguez, Marco Pizzolato, Alessandro Daducci
We propose a multimodal joint estimation that aims at exploiting the complementary information of diffusion and multi-echo spin echo data to disentangle the contributions and properties of the main tissue microstructure compartments. We recovered T2, diffu ...
