Background: Mitral valve prolapse (MVP) is a frequent disease that can be complicated by mitral regurgitation (MR), heart failure, arterial embolism, rhythm disorders, and death. Left ventricular (LV) replacement myocardial fibrosis, marker of maladaptive remodeling, has been described in patients with MVP, but the implications this finding remain scarcely explored. We aimed at assessing prevalence, pathophysiological prognostic significance LV fibrosis through late gadolinium enhancement...
Background and Purpose— Acute stroke patients with a large ischemic core may still benefit from mechanical thrombectomy (MT), but the predictors of clinical outcome are not well known after MT. We investigated imaging factors associated good mortality at 90 days in acute baseline treated Methods— Data multicentric prospective ETIS (Endovascular Treatment Ischemic Stroke) registry consecutive MT January 1, 2012, to August 31, 2016, were retrospectively analyzed. Baseline was defined as...
The purpose of this study was to evaluate the ability ultra-high-resolution computed tomography (UHR-CT) assess stapes and chorda tympani nerve anatomy using a deep learning (DLR), model-based, hybrid iterative reconstruction algorithm compared simulated conventional CT. CT acquisitions were performed with Mercury 4.0 phantom. Images acquired 1024 × matrix 0.25 mm slice thickness reconstructed DLR, algorithms. To simulate CT, images also 512 0.5 thickness. Spatial resolution, noise power...
Abstract Background We evaluated the accuracy of magnetic resonance imaging (MRI) computed tomography (CT)-like sequences compared to normal-resolution CT (NR-CT) and super-high-resolution (SHR-CT) for planning cochlear implantation. Methods Six cadaveric temporal bone specimens were used. 3-T MRI scans performed using radial volumetric interpolated breath-hold (STARVIBE), pointwise-encoding time reduction with acquisition (PETRA), ultrashort echo (UTE) sequences. on two scanners SHR-CT...
Background and hypothesis There is no consensus on the optimal endovascular management of extracranial internal carotid artery steno-occlusive lesion in patients with acute ischemic stroke due to tandem occlusion. We hypothesized that intracranial mechanical thrombectomy plus emergent stenting (and at least one antiplatelet therapy) superior alone Study design TITAN an investigator-initiated, multicenter, prospective, randomized, open-label, blinded-endpoint (PROBE) study. Eligibility...
Human face perception requires a network of brain regions distributed throughout the occipital and temporal lobes with right hemisphere advantage. Present theories consider this as either processing hierarchy beginning inferior gyrus (occipital area; IOG-faces/OFA) or multiple-route nonhierarchical components. The former predicts that removing IOG-faces/OFA will detrimentally affect downstream stages, whereas latter does not. We tested prediction in human patient (Patient S.P.) requiring...
Objective We aimed to characterize the association between pretreatment lesional volume measured on diffusion‐weighted images and functional outcome, estimate impact thrombectomy efficacy for ischemic stroke with anterior proximal intracranial arterial occlusion. Methods Anterior circulation patients who had imaging in THRACE study were included. Lesional was semiautomatically segmented. Logistic regression applied model clinical outcome as a function of volume. Outcomes included...
<b>Purpose:</b> The assessment of gliomas by <sup>18</sup>F-FDOPA PET imaging in adjunct to MRI showed high performance combining static and dynamic features non-invasively predict the isocitrate dehydrogenase (IDH) mutations 1p/19q co-deletion, which World Health Organization classified as significant parameters 2016. current study evaluates whether other radiomics further improve contributions each these performance. <b>Methods:</b> Our included seventy-two, retrospectively selected, newly...
Brain regions located between the right fusiform face area (FFA) in middle gyrus and temporal pole may play a critical role human identity recognition but their investigation is limited by large signal drop-out functional magnetic resonance imaging (fMRI). Here we report an original case who suddenly unable to recognize of faces when electrically stimulated on focal location inside this intermediate region anterior gyrus. The reliable transient deficit occurs without any change percept, even...
The purpose of this study was to evaluate the achievable radiation dose reduction an ultra-high resolution computed tomography (UHR-CT) scanner using deep learning reconstruction (DLR) while maintaining temporal bone image quality equal or better than high-resolution CT (HR-CT).
We performed a prospective study to evaluate the values of dynamic four-dimensional computed tomography in assessing suspected chronic scapholunate instability. Forty patients were evaluated with radiographs, arthrography, and tomography. On plain radiographs tomography, we found 16 definite instability, five questionable 19 absence used size gap during radioulnar deviation. The mean maximal lowest instability highest those When comparing sizes absent range was significantly higher conclude...
Although immersive technologies such as virtual reality are constantly growing for personal and professional purposes, their use can often induce a transient state of discomfort known cybersickness, resulting in numerous symptoms perceptive-motor vulnerability. In an attempt to develop leads mitigate encouraging findings have reported decreased during the presentation pleasant smells. However, diffusion smells ecological settings is very challenging. An interesting alternative could reside...
