Multilayer Networks [PDF]

, 2014
In most natural and engineered systems, a set of entities interact with each other in complicated patterns that can encompass multiple types of relationships, change in time, and include other types of complications.

Clinical Feasibility of Deep Learning Contrast Synthesis From MR Fingerprinting in Knee Osteoarthritis

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Magnetic Resonance Fingerprinting (MRF) enables rapid quantitative parameter mapping from which synthetic clinical contrast images can be derived using deep learning (DL). Purpose This study evaluates the reliability and interchangeability of MRF‐derived synthetic knee MRI relative to conventional MRI in patients with osteoarthritis.

Communities Unfolding in Multislice Networks [PDF]

, 2011
Discovering communities in complex networks helps to understand the behaviour of the network. Some works in this promising research area exist, but communities uncovering in time-dependent and/or multiplex networks has not deeply investigated yet. In this paper, we propose a communities detection approach for multislice networks based on modularity ...

Simultaneous multislice excitation by parallel transmission [PDF]

Magnetic Resonance in Medicine, 2013
PurposeA technique is described for simultaneous multislice (SMS) excitation using radiofrequency (RF) parallel transmission (pTX).MethodsSpatially distinct slices are simultaneously excited by applying different RF frequencies on groups of elements of a multichannel transmit array.

Impacts of Simultaneous Multislice Acquisition on Sensitivity and Specificity in fMRI [PDF]

, 2018
Simultaneous multislice (SMS) imaging can be used to decrease the time between acquisition of fMRI volumes, which can increase sensitivity by facilitating the removal of higher-frequency artifacts and boosting effective sample size.

Navigator‐Based Slice Tracking for Multiband Accelerated Liver DWI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Clinical liver diffusion‐weighted imaging (DWI) suffers from long measurement time and respiratory motion. In this study, we employ a navigator‐based slice tracking technique (NAV) to prospectively compensate for respiratory motion in multiband (MB) accelerated liver DWI.

Evaluation and Validation of clinical 4.23 T sodium MRI in animals and human: Application of oblique multi-slice spin-echo pulse sequence [PDF]

, 2009
Objective: Application of high-field 4.23 T MRI clinical imager was demonstrated for sodium-magnetic resonance imaging (MRI) data acquisition. Primary hypothesis: Sodium [Na] in brain is MR visible. Secondary hypothesis was, if, application of multislice

Holographic particle localization under multiple scattering [PDF]

, 2019
We introduce a novel framework that incorporates multiple scattering for large-scale 3D particle-localization using single-shot in-line holography. Traditional holographic techniques rely on single-scattering models which become inaccurate under high ...

Role of multislice computed tomography and three-dimensional rendering in the evaluation of maxillofacial injuries

Journal of Oral and Maxillofacial Radiology, 2017
Aims and Objectives: The aim of this is to identify and classify maxillofacial fractures using multislice computed tomography (CT) and identify the advantages of three-dimensional (3D) rendered images over two-dimensional axial images in evaluating ...

Single‐Breathhold 3D MR Elastography in the Liver, With Simultaneous R2* and PDFF Mapping

Magnetic Resonance in Medicine, EarlyView.
Purpose To develop a sequence for the rapid acquisition of MR elastography (MRE) parameters in 3D, with simultaneous measurement of proton‐density fat fraction (PDFF) and R2* for multiparametric assessment of liver disease. Methods The proposed sequence uses an interleaved motion‐encoding scheme to acquire 3D volumes of all motion encodings and wave ...
