Computed tomography versus short sequence magnetic resonance imaging in acute ischaemic stroke
It is undisputable that the acute management of stroke requires a fast and accurate diagnostic imaging modality. We read with interest and congratulate Kumar et al. on their article discussing the superiority and benefits of the use of magnetic resonance imaging (MRI) in acute ischaemic stroke (AIS) [1]. The authors suggest that MRI can improve the diagnostic accuracy of computed tomography (CT) negative AIS and allow better selection of patients for reperfusion therapies. Moreover, MRI may help avoid hospital admissions for patients with stroke mimics, facilitate earlier discharge, reduce overall hospital costs and play a...

The susceptibility vessel sign containing two compositions on 3-TT2*-weighted image and single corticosubcortical infarct on diffusion-weighted image are associated with cardioembolic stroke
Although accurate diagnosis of the ischemic stroke subtype is one of the most important factors for selection of therapeutic approach, it is sometimes difficult at the time of admission. We previously reported that susceptibility vessel sign (SVS) with two layers (termed two-layered SVS) on 3-T-T2*-weighted image (T2*-WI) might be useful to predict cardioembolic stroke in patients with cerebral major vessel occlusion. We studied about biomarkers on magnetic resonance imaging (MRI), including two-layered SVS for diagnosing cardioembolic stroke.

Thrombolysis for acute stroke in patient with systemic lupus erythematosus: A case report
We present a case of 40-year-old woman with an acute stroke who received rt-PA. Magnetic resonance imaging (MRI) revealed a large ischemic stroke in right hemisphere and a magnetic resonance angiography (MRA) revealed signs of vasculitis.

Letter to editor: Is improved access to magnetic resonance imaging imperative for optimal ischemic stroke care?
We read the article “Is improved access to magnetic resonance imaging imperative for optimal ischemic stroke care?” [1] with great interest. The authors have presented a concise and informative summary of the use of MRI in ischemic stroke care, emphasizing its significance in diagnosis, management, and secondary pr evention. We appreciate the authors for presenting a comprehensive summary of the use of MRI in ischemic stroke care. However, we have certain points to make about the comparison of the MR scanners provided in this article.

Development of a stroke risk score with MRI asymptomatic brain lesions attributes to evaluate prognostic vascular events
The use of a combination of stroke predictors, such as clinical factors and asymptomatic lesions on brain magnetic resonance imaging (MRI), may improve the accuracy of stroke risk prediction. Therefore, we attempted to develop a stroke risk score for healthy individuals.

Arterial spin-labeling magnetic resonance imaging for diagnosis of early seizure after stroke
Arterial spin-labeling (ASL) is a non-contrast-enhanced sequence of magnetic resonance imaging (MRI) to evaluate cerebral perfusion. ASL has been widely used in cerebrovascular diseases [1]. Previously, we reported the use of ASL for the diagnosis of late seizure after stroke [2]. Here we report a first case of ASL in a patient with early seizure after stroke.

Sensorimotor Modulation by Botulinum Toxin A in Post-Stroke Arm Spasticity: Passive Hand Movement
In post-stroke spasticity, functional imaging may uncover modulation in the central sensorimotor networks associated with botulinum toxin type A (BoNT) therapy. Investigations were performed to localize brain activation changes in stroke patients treated with BoNT for upper limb spasticity using functional magnetic resonance imaging (fMRI).

Association between leukoaraiosis and hemorrhagic transformation after cardioembolic stroke due to atrial fibrillation and/or rheumatic heart disease
Cardioembolic stroke due to atrial fibrillation (AF) and/or rheumatic heart disease (RHD) often involves hemorrhagic transformation (HT), and we examined whether leukoaraiosis (LA) was associated with HT in these cases. We prospectively enrolled 251 patients who were admitted to two hospitals within one month of experiencing cardioembolic stroke due to AF/RHD. LA severity was assessed using three visual rating scales. HT was identified in 99 patients (39.4%) based on baseline computed tomography (CT) and post-admission magnetic resonance imaging or second CT.

Restricted access in the emergency department prevents MRI from being the workhorse for ischemic stroke care
We express our sincere gratitude to Wong et al. for their interest in our recent publication, “Is improved access to magnetic resonance imaging imperative for optimal ischemic stroke care?” [1]. We value the insights provided by the authors regarding the potential of magnetic resonance imaging (MRI) as the preferred imaging modality for acute ischemic stroke (AIS). Additionally, we appre ciate their valuable contribution on the utilization of short-sequence head MRI in addition to computed tomography (CT) for AIS evaluation at their center, which provides further evidence for the use of MRI in this context.

Microbleeds in ischemic stroke are associated with lower serum adiponectin and higher soluble E-selectin levels
Conclusions: Endothelial injury may play a role in the pathogenesis of CMBs, and serum levels of adiponectin and sE-selectin were closely related to CMBs. Adiponectin might be protective for the prevalence of CMBs.

Response to a letter regarding a paper entitled, “Post-intervention TCD examination may be useful to predict outcome in acute ischemic stroke patients with successful intra-arterial intervention”
We thank Dr. Dale Ding for his thoughtful comments regarding our previous study, entitled “Post-intervention TCD examination may be useful to predict outcome in acute ischemic stroke patients with successful intra-arterial (IA) intervention” . He clearly presented the potential utility of the pulsatility index (PI) of the middle cerebral artery citing a recent study reported by Uzuner et al. . As he pointed out, our study has a limitation regarding the definition of the poor outcome. Because our study was retrospective and limited to hospitalization records, we defined poor outcomes as in-hospital death or decompressiv...

Association of functional genetic Variants in PPARδ encoding Peroxisome Proliferator-Activated Receptor Delta with ischemic stroke in Chinese uyghur populat ion
PPARδ belongs to a receptor family of ligand-activated transcription factors involved in the regulation of inflammation, cellular glucose uptake, protection against atherosclerosis and endothelial cell function. Through these effects, they might be involved with the ischemic stroke (IS). We recruited 200 subjects (100 IS patients diagnosed by CTs or/and magnetic resonance imaging (MRI) and 100 normal healthy controls from Chinese Uyghur Population) to assess the nature of the functional polymorphisms of PPARδ+294T/C and any links with IS in this unique population.
