...: Stroke lesion volume on MRI or CT provides objective evidence of tissue injury as a consequence of ischemic stroke. Measurement of “final” lesion volume at 24-h following endovascular therapy (post-EVT) has been used in multiple studies as a surrogate for clinical outcome. However, despite successful...

... with manifest arterial disease. Patients had baseline CAS duplex measurements and a 1.5T brain MRI at baseline and after 4 years of follow-up. Mean change in hemispheric brain volumes (% of intracranial volume [ICV]) was estimated between baseline and follow-up for left-sided and right-sided CAS across three...

...Dimitri Renard; Sabine Laurent-Chabalier; Adelina Leonte; Marc Hackius; Teodora Parvu; Anne Wacongne; Eric Thouvenot Background: Cerebellar superficial siderosis (SS) has been recently reported to be present in about 10% of both hereditary and sporadic cerebral amyloid angiopathy (CAA) on 3T MRI...

.... Materials and Methods: We assessed vessel dimensions on MRI of the symptomatic carotid artery in 164 patients from the Plaque At RISK study. This study included patients with recent ischemic neurological event and ipsilateral carotid artery stenosis <70%. The cross section with the largest wall area (WA...

... complicate infective endocarditis (IE). We aimed to describe the magnetic resonance imaging (MRI) characteristics of IIA. Methods: We reviewed IIAs among 116 consecutive patients with active IE by conducting a neurological evaluation at a single tertiary referral center from January 2015 to July 2016. MRIs...

... patients who received a baseline screening brain MRI from January 2000 to February 2017. This study group was further refined by excluding patients who had a history of clinical ischemic disease as defined by having a stroke or transient ischemic attack (TIA). Brain MRIs were reviewed for SBI. Baseline...

...-iodoamphetamine single-photon emission CT (SPECT) with acetazolamide (ACZ) challenge is widely carried out, but using ACZ becomes problematic owing to its off-label use and its adverse effects. Here, we report the efficacy of dynamic susceptibility contrast MRI (DSC-MRI) for the evaluation of CVR in MMD patients...

... study on patients with first-ever ischemic stroke. On brain MRI we assessed the number of silent lacunes as none, single, or multiple and we calculated stratified incidence rates of the outcomes. Cox proportional hazard ratios (HRs) adjusted for age, gender, congestive heart failure, hypertension...

...; 790 men), who underwent brain MRI and abdominal CT. Risk factors, anthropometric parameters and clinical information were obtained. CMBs were evaluated through T2*-weighted gradient-recalled echo MRI. The cross-sectional surface areas of the abdominal fat compartments were calculated. Study subjects...

Diabetes mellitus Blood brain barrier MRI Outcome Stroke Diabetes was defined according to American Diabetes Association criteria [ 18 ]. The duration of diabetes and fasting plasma glucose (FPG) on admission were recorded...

... (GM) and white matter (WM) have different vulnerabilities to ischemia. Thus, we compared the evolution of ischemic lesions within WM and GM using MRI. Methods: From a European multicenter prospective database (I-KNOW), available T1-weighted images were identified for 50 patients presenting...

... patients. Methods: We included consecutive eligible patients who presented to the out-patient memory clinic at the Massachusetts General Hospital from 2007 to 2010 and had appropriate MRI, including blood-sensitive sequences. We analyzed the prevalence and topography of cSS according to demographic...

.... Posterior communicating artery MRI Hemodynamics Lateral thalamic infarction Vascular geometry Cerebral infarction Lateral thalamic infarction (LTI) is the most common pattern of isolated thalamic infarction. LTI is mostly caused by small vessel disease; occlusion of the small perforating...

... underwent a MRI scan before intravenous thrombolytic therapy was included. DWI lesions were divided into 6 patterns (territorial, other cortical, small superficial, internal border zone, small deep, and other deep infarcts). Lesion volumes were measured by dedicated imaging processing software. Favorable...

... approach. Methods: In 329 subjects from the population-based Rotterdam Study, all with ultrasound-confirmed carotid wall thickening, we performed a multi-detector CT and a high-resolution MRI of the carotid artery bifurcation at both sides. On the CT examinations, we quantified the volume of intraplaque...

... outcome, cell death expression, and brain protection markers including ROS enzyme NOX-4. MRI included DWI (ADC maps), DTI (tractography), and PWI (CBF, CBV and MTT). Results: The lesion size was similar in pMCAO rats. Animals with a heterogeneous pattern in ADC maps showed better functional outcome...

... in patients with asymptomatic carotid stenosis including cerebrovascular reserve testing, MRI of plaque composition, ultrasound of plaque echolucency, and transcranial Doppler evaluation for microemboli. The highest quality evidence thus far in the literature includes only systematic reviews and meta-analyses...

... and US data (presence/absence of carotid stenosis, carotid stenosis side). DIR lesions (DIRlns) were scored according to the Consensus recommendations for MS cortical lesion scoring using double inversion recovery MRI [ 18 ]. Total intracortical lesions number and localization were computed in each...
