Optimal Dual-VENC Unwrapping in Phase-Contrast MRI
(Institute of Electrical and Electronics Engineers Inc., 2019)
© 2018 IEEE. Dual-VENC strategies have been proposed to improve the velocity-to-noise ratio in phase-contrast MRI. However, they are based on aliasing-free high-VENC data. The aim of this paper is to propose a dual-VENC ...
Accelerating dual cardiac phase images using phase encoding trajectories
(ELSEVIER SCIENCE INC, 2016)
A three-dimensional dual-cardiac-phase (3D-DCP) scan has been proposed to acquire two data sets of the whole heart and great vessels during the end-diastolic and end-systolic cardiac phases in a single free-breathing scan. ...
Multiple motion encoding in phase-contrast MRI: A general theory and application to elastography imaging
(Elsevier, 2022)
While MRI allows to encode the motion of tissue in the magnetization's phase, it remains yet a challenge to obtain high fidelity motion images due to wraps in the phase for high encoding efficiencies. Therefore, we propose ...

Automatic correction of background phase offset in 4D-flow of great vessels and of the heart in MRI using a third-order surface model
(Springer, 2019-12)
Objective: To evaluate an automatic correction method for velocity offset errors in cardiac 4D-flow acquisitions. Materials and methods: Velocity offset correction was done in a plane-by-plane scheme and compared to a ...
U-CatcHCC: An Accurate HCC Detector in Hepatic DCE-MRI Sequences Based on an U-Net Framework
(Springer, 2018-01-01)
This paper presents a novel framework devoted to the detection of HCC (Hepato-Cellular Carcinoma) within hepatic DCE-MRI (Dynamic Contrast-Enhanced MRI) sequences, by a deep learning approach. In clinical routine, radiologists ...
Relative pressure estimation from velocity measurements in blood flows: State-of-the-art and new approaches
(Wiley, 2018)
The relative pressure difference across stenotic blood vessels serves as an important clinical index for the diagnosis of many cardiovascular diseases. While the clinical gold standard for relative pressure difference ...
Using magnetic resonance phase-contrast velocity mapping for diagnosing pelvic congestion syndrome
(ROYAL SOC MEDICINE PRESS LTD, 2011)
Objective: To evaluate phase-contrast velocity mapping (PCVM) as a diagnostic tool for pelvic congestion syndrome and comparing this approach with direct venography.
A Parallel Framework for HCC Detection in DCE-MRI Sequences with Wavelet-Based Description and SVM classification
(Assoc Computing Machinery, 2018-01-01)
In this article, we propose a complete framework devoted to detect liver HCC (Hepato-Cellular Carcinoma) tumors within DCE-MRI (Dynamic Contrast Enhanced-MRI) sequences. Our system employs different phases of these hepatic ...
