The utility of computed tomographic perfusion (CTP)-based patient selection for intra-arterial treatment acute ischemic stroke has not been proven in randomized trials and requires further study a cohort that was selected based on CTP. Our objective to the relationship between CTP-derived parameters outcome effect patients with because proximal intracranial arterial occlusion.We included 175 who underwent CTP Multicenter Randomized Clinical Trial Endovascular Treatment Acute Ischemic Stroke...
Purpose To investigate the prevalence of symptomatic carotid web in patients with acute ischemic stroke due to intracranial large vessel occlusion, determine clinical and imaging profile as well their association stroke, interobserver agreement assessment webs. Materials Methods All (n = 500) Multicenter Randomized Clinical Trial Endovascular Treatment for Acute Ischemic Stroke Netherlands (MR CLEAN) whom bifurcation could be assessed 443) were included. The presence a at bifurcations was...
Background CT perfusion (CTP) is used to estimate the extent of ischemic core and penumbra in patients with acute stroke. CTP reliability, however, limited. This study aims identify regions misclassified as on CTP, using infarct follow-up noncontrast CT. We aim assess differences volumetric characteristics these compared areas that ended up follow-up. Materials Methods included 35 >100 mm brain coverage CTP. processing was performed Philips software (IntelliSpace 7.0). Final automatically...
<h3>BACKGROUND AND PURPOSE:</h3> Thrombus CT characteristics might be useful for patient selection intra-arterial treatment. Our objective was to study the association of thrombus with outcome and treatment effect in patients acute ischemic stroke. <h3>MATERIALS METHODS:</h3> We included 199 whom thin-section NCCT CTA within 30 minutes from each other were available Multicenter Randomized Clinical Trial Endovascular Treatment Acute stroke Netherlands (MR CLEAN) study. assessed following...
Background: The presence of extracranial carotid disease (ECD) is associated with less favorable clinical outcomes in patients acute ischemic stroke caused by intracranial proximal occlusion. Acute intra-arterial treatment (IAT) the setting and lesions considered challenging, whether it yields improved remains uncertain. Objective: To examine ECD modified effect IAT for anterior circulation Design: Prespecified subgroup analysis a randomized trial endovascular Netherlands. (Trial...
The absence of opacification on CTA in the extracranial ICA acute ischemic stroke may be caused by atherosclerotic occlusion, dissection, or pseudo-occlusion. latter is explained sluggish stagnant flow a patent artery distal intracranial occlusion. This study aimed to explore accuracy for differentiating pseudo-occlusion from true occlusion ICA.All patients Multicenter Randomized Clinical Trial Endovascular Treatment Acute Ischemic Stroke Netherlands (MR CLEAN) with an apparent and available...
Background and Purpose It has been suggested that CT Perfusion acquisition times <60 seconds are too short to capture the complete in out-wash of contrast tissue, resulting incomplete time attenuation curves. Yet, these acquisitions not uncommon clinical practice. The purpose this study was investigate occurrence curve truncation 48 quantify its effect on ischemic core penumbra estimation patients with acute stroke due a proximal intracranial arterial occlusion anterior circulation....
Thrombus perviousness is strongly associated with functional outcome and intravenous alteplase treatment success in patients acute ischemic stroke. Accuracy of thrombus attenuation increase (TAI) assessment may be compromised by a heterogeneous composition interobserver variations currently used manual measurements. We hypothesized that TAI more clinical outcomes when evaluated on the entire thrombus. In 195 patients, five measures were performed: one placing three regions interest...
<h3>BACKGROUND AND PURPOSE:</h3> Semiautomatic measurement of ICA stenosis potentially increases observer reproducibility. In this study, we assessed the diagnostic accuracy and interobserver reproducibility a commercially available semiautomatic on CTA estimated agreement among different software packages. <h3>MATERIALS METHODS:</h3> We analyzed 141 arteries from 90 patients with TIA or ischemic stroke. Manual measurements were performed by 2 neuroradiologists. using 4 methods (3mensio...
The increasing size of medical imaging data, in particular time series such as CT perfusion (CTP), requires new and fast approaches to deliver timely results for acute care. Cloud architectures based on graphics processing units (GPUs) can provide the capacity required delivering results. However, CTP datasets makes transfers cloud infrastructures time-consuming therefore not suitable situations. To reduce this transfer time, work proposes a lossless compression algorithm data. exploits...
