Liver biopsy is the gold standard for assessing fibrosis but has several limitations. We evaluated a noninvasive method, so-called diffusion-weighted magnetic resonance imaging (DWMRI), which measures apparent diffusion coefficient (ADC) of water, diagnosis liver in patients with chronic hepatitis C virus (HCV). analyzed 20 healthy volunteers and 54 HCV (METAVIR: F0, n = 1; F1, 30; F2, 8; F3, 5; F4, 10) prospectively included. Patients moderate-to-severe (F2-F3-F4) had hepatic ADC values...
In sports medicine, there is increasing interest in quantifying the elastic properties of skeletal muscle, especially during extreme muscular stimulation, to improve our understanding impact alterations muscle stiffness on resulting pain or injuries, as well mechanisms underlying relationships between these parameters. Our main objective was determine whether real-time shear-wave elastography (SWE) can monitor changes quadriceps elasticity an mountain ultra-marathon, a powerful mechanical...
Background— Delayed stent implantation after restoration of normal epicardial flow by a minimalist immediate mechanical intervention aims to decrease the rate distal embolization and impaired myocardial reperfusion percutaneous coronary intervention. We sought confirm whether delayed stenting (DS) approach (24–48 hours) improves reperfusion, versus stenting, in patients with acute ST-segment–elevation infarction undergoing primary Methods Results— In prospective, randomized, open-label...
To develop a three-dimensional (two dimensions + time) convolutional neural network trained with displacement encoding stimulated echoes (DENSE) data for and strain analysis of cine MRI.In this retrospective multicenter study, deep learning model (StrainNet) was developed to predict intramyocardial from contour motion. Patients various heart diseases healthy controls underwent cardiac MRI examinations DENSE between August 2008 January 2022. Network training inputs were time series myocardial...
In acute stroke it is no longer sufficient to detect simply ischemia, but also try evaluate reperfusion/recanalization status and predict eventual hemorrhagic transformation. Arterial spin labeling (ASL) perfusion may have advantages over contrast-enhanced perfusion-weighted imaging (cePWI), susceptibility weighted (SWI) has an intrinsic sensitivity paramagnetic effects in addition its ability small areas of bleeding hemorrhage. We want determine here if their combined use follow-up at 3T...
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 based on subtraction of a temporal reference phase map and is, therefore, intrinsically sensitive to tissue motion (including deformation) external perturbation magnetic field. Reference-free (or reference-less) has been previously described by Rieke was 2-D polynomial fit performed data...
A novel ultrasound (US) high-channels platform is a pre-requisite to open new frontiers in diagnostic and/or therapy by experimental implementation of innovative advanced US techniques. To date, few systems with more than 1000 transducers permit full and simultaneous control both transmission receiving all single elements arrays. powerful for implementing 4-D (real-time 3-D) strategies, offering research access, presented this paper. It includes 1024-elements array prototype designed cardiac...
Purpose In this study, we proposed an efficient free‐breathing strategy for rapid and improved cardiac diffusion‐weighted imaging (DWI) acquisition using a single‐shot spin‐echo echo planar (SE‐EPI) sequence. Methods : A real‐time slice‐following technique during was combined with sliding acquisition‐window prior Principal Component Analysis temporal Maximum Intensity Projection (PCAtMIP) postprocessing of in‐plane co‐registered images. This methodology applied to 10 volunteers quantify the...
Background and Objective. The prevention of ascending thoracic aortic aneurysms (ATAAs), which affect thousands persons every year worldwide, remains a major issue. ATAAs may be caused by anything that weakens the wall. Altered hemodynamics, concerns majority patients with bicuspid valves, has been shown to related such weakening contribute ATAA development progression. However underlying mechanisms remain unclear computational modeling in this field could help significantly elucidate how...
