Differential diagnoses of ischemic stroke using imaging.

[Differential diagnoses of ischemic stroke using imaging]. Radiologe. 2019 Jun 14;: Authors: Yilmaz U Abstract Diffusion-weighted imaging enables us to detect acute ischemic stroke early and with high sensitivity and specificity. Its signal changes are based on decreased diffusion of water molecules that is caused by cytotoxic edema. Several different neurological diseases can also cause restricted diffusion and therefore mimic stroke. These can generally be reliably distinguished from ischemic stroke based on location, morphology and signal behavior in other magnetic resonance imaging sequences.

CONCLUSIONS: The presence of MRI-positive vulnerable carotid plaques including IPH, LRNC, and TRFC is positively associated with symptomatic clinical presentation. Therefore, carotid plaque MRI might be a useful risk stratification tool in determining the risk of ischemic stroke. PMID: 31738030 [PubMed - as supplied by publisher]

Temporary middle cerebral artery occlusion (MCAO) in sheep allows modeling of acute large vessel occlusion stroke and subsequent vessel recanalization. However, rapid and precise imaging-based assessment of vessel occlusion and the resulting perfusion deficit during MCAO still represents an experimental challenge. Here, we tested feasibility and suitability of a strategy for MCAO verification and perfusion deficit assessment. We also compared the extent of the initial perfusion deficit and subsequent lesion size for different MCAO durations. The rete mirabile prevents reliable vascular imaging investigation of middle cereb...

Authors: Yoshida K, Miyamoto S, SMART-K Study Group Abstract With recent advances in medical treatments for carotid artery stenosis (CS), indications for carotid surgery should be more carefully considered for asymptomatic CS (ACS). Accurate stratification of ACS should be based on the risk of cerebral infarction, and subgroups of patients more likely to benefit from surgical treatment should be differentiated. Magnetic resonance imaging (MRI) offers a non-invasive, accurate modality for characterizing carotid plaque. Intraplaque hemorrhage (IPH) seems the most promising feature of vulnerable plaque detectable by M...

ConclusionThe occurrence and severity of CCD are related to the degree of low supratentorial perfusion and the decrease in the ADC value of infarct focus.

AbstractObjectivePosterior circulation ischemic stroke (PCiS) constitutes 20 –30% of ischemic stroke cases. Detailed information about differences between PCiS and anterior circulation ischemic stroke (ACiS) remains scarce. Such information might guide clinical decision making and prevention strategies. We studied risk factors and ischemic stroke subtypes in PCiS vs. ACiS and lesion location on magnetic resonance imaging (MRI) in PCiS.MethodsOut of 3,301 MRIs from 12 sites in the National Institute of Neurological Disorders and Stroke (NINDS) Stroke Genetics Network (SiGN), we included 2,381 cases with acute DWI lesi...

ConclusionsAttention should be paid to ischemic stroke recurrence as a complication of IV t-PA, and preparation for mechanical thrombectomy is warranted. Further study of the left atrial appendage is needed to clarify the mechanisms of onset.

AbstractBackground and purposeThe significance of white matter hyperintensities (WMHs) in the setting of mechanical thrombectomy (MT) remains poorly documented. We assessed whether pre-existing WMHs burden was associated with baseline clinical and imaging factors and neurological outcome in patients undergoing MT.MethodsThis retrospective single-center study included consecutive acute ischemic stroke (AIS) patients with stroke due to large vessel occlusion treated with MT. WMHs were assessed on baseline T2 fluid-attenuated inversion recovery magnetic resonance imaging. Neurological outcome was assessed at day 90 by the mod...

Abstract Adipose-derived stromal cell (ASC) therapy is currently investigated as a new treatment option for patients with ischemic heart disease (IHD). The aim of this study was to evaluate the effect of ASC therapy in patients with chronic IHD measuring myocardial perfusion and cardiac function using cardiac magnetic resonance imaging (CMRI). Patients were included in MyStromalCell trial, a phase II, randomized, double-blinded, placebo-controlled study investigated the effect of ASCs in patients with chronic IHD with preserved left ventricular ejection fraction (LVEF). In total, 41 of 60 patients underwent cine, ...

Endothelial progenitor cells (EPCs) participate in the repair and regeneration of vascular injury through the combination of cell replacement and bystander effects. Here, we evaluated the biological function of EPCs in treating a mouse model of cerebral ischaemic stroke, using dual-mode bioluminescence and magnetic resonance imaging to trace EPCs in vivo.Main methodsWe constructed a viral ...

Here, we report a case involving a 67-year-old Japanese woman with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) associated with a novel in-frame complex rearrangement in the NOTCH3 gene. The patient had gradually developed cognitive impairment since the occurrence of an ischemic stroke at the age of 53 years. Her mother had a history of stroke and dementia. Fluid-attenuated inversion recovery magnetic resonance imaging of the brain showed hyperintense lesions in the bilateral temporal poles, external capsules, and periventricular white matter accompanied by multiple c...
