Lower 25-hydroxyvitamin D is associated with severer white matter hyperintensity and cognitive function in patients with non-disabling ischemic cerebrovascular events
Vascular cognitive impairment (VCI) is the second most common type of cognitive impairment, referring to the entire spectrum of cognitive impairment contributed by cerebrovascular pathology1. Due to the progressively higher incidence of stroke and cerebrovascular diseases, VCI, including post-stroke cognitive impairment are the leading causes of disability epidemic worldwide2-3. White matter lesions, manifested as white matter hyperintensities (WMH) on T2-weighted magnetic resonance imaging (MRI) scans, are one of the most common pathological characteristics of VCI4.

Perivascular spaces mediate a relationship between diabetes and other cerebral small vessel disease markers in cerebrovascular and neurodegenerative diseases
Cerebral small vessel disease (SVD) is used to describe heterogeneous pathological changes in perforating arterioles, venules, and capillaries that supply blood to subcortical structures.1 These pathological changes manifest on magnetic resonance imaging (MRI) as quantifiable volumetric measures. Established markers of SVD identified on MRI include deep white matter hyperintensities (dWMH) and periventricular white matter hyperintensities (pWMH) of presumed vascular origin and lacunes, and MRI visible enlarged perivascular spaces (PVS) in the white matter (wmPVS) or basal ganglia (bgPVS).

The charlotte large artery occlusion endovascular therapy outcome score compares favorably to the critical area perfusion score for prognostication before basilar thrombectomy
Late window endovascular thrombectomy (EVT) trials enrolled patients presenting with an internal carotid artery (ICA) or proximal middle cerebral artery (MCA) occlusion using computed tomography perfusion (CTP) or magnetic resonance imaging perfusion selection criteria.1,2 Radiographic1 or clinical mismatch2 was required for inclusion in these landmark studies. Although perfusion imaging is not always used for patient selection in early window anterior circulation thrombectomy,3 CTP ischemic core volume is independently associated with functional outcome improvement in the 0-6-hour time window when good endovascular reperfusion is achieved.

A case of ischemic stroke associated with protein-losing gastroenteropathy and protein S deficiency
We report a 24-year-old woman who developed acute dysarthria and right hemiplegia 4 months after delivering her first baby by cesarean section. Diffusion-weighted magnetic resonance imaging showed a high-intensity signal in the left anterior cerebral artery territory and middle cerebral artery territory.

Associations of carotid artery flow parameters with MRI markers of cerebral small vessel disease and patterns of brain atrophy
Cerebral small vessel disease (CSVD) affects small arteries, arterioles, veins and capillaries of the brain. Although a common and often silent condition occurring among healthy elderly people, it is associated with stroke, dementia, gait disturbances, cognitive decline and depression.1 –4 Magnetic resonance imaging (MRI) markers of CSVD include: white matter changes (WMC), microbleeds (MB) and lacunar infarctions (LAC).5 They can be investigated either individually or be viewed as a dynamic whole-brain disease.

Investigation of inpatient convalescent rehabilitation outcomes in branch atheromatous disease
Branch atheromatous disease (BAD) is a form of ischemic stroke characterized by unique findings in penetrating artery infarcts on magnetic resonance imaging (MRI) and progressive motor deficits in the acute phase.1-5 In daily practice, the most prominent clinical issue in patients with BAD is neurological deterioration and the consequent development of severe neurological sequelae requiring rehabilitation.

Transient global amnesia - hippocampal lesions in magnetic resonance imaging
Transient global amnesia is a benign syndrome characterized by a sudden onset loss of anterograde amnesia with full recovery. Magnetic resonance of the brain including diffusion –weighted imaging of patients with transient global amnesia revealed the presence of punctate hyperintense signal abnormalities in the hippocampus.

Low NIHSS score large vessel occlusion caused by infective endocarditis treated with thrombectomy
A 24-year-old woman had undergone dental treatment 3 weeks before and had a mild fever for a week. She presented to the emergency department with the chief complaint of weakness in the right upper limb after waking up. She had mild paralysis of the right upper limb (National Institutes of Health Stroke Scale [NIHSS] score 1). Head magnetic resonance imaging (MRI) showed scattered infarcts in the left frontal and parietal lobes and left internal cerebral artery (ICA) occlusion (Fig. 1A, B). Cerebral angiography showed that the left ICA was occluded immediately after its origin (Fig.

Prediction of cerebral hyperperfusion following carotid endarterectomy using intravoxel incoherent motion magnetic resonance imaging
One of the risk factors for cerebral hyperperfusion following carotid endarterectomy (CEA) is a chronic reduction in cerebral perfusion pressure due to internal carotid artery (ICA) stenosis, which is clinically detected as increased cerebral blood volume (CBV). The perfusion fraction (f) is one of the intra-voxel incoherent motion (IVIM) parameters obtained using magnetic resonance (MR) imaging that theoretically reflects CBV. The present study aimed to determine whether preoperative IVIM-f on MR imaging predicts development of cerebral hyperperfusion following CEA.

Diagnostic performance of intraoperative cone beam computed tomography compared with postoperative magnetic resonance imaging for detecting hemorrhagic transformation after endovascular treatment following large vessel occlusion
Early detection of hemorrhagic transformation (HT) in patients with large vessel occlusion (LVO) after endovascular treatment is important for postoperative patient management. We investigated the diagnostic performance of intraoperative cone beam computed tomography (CBCT) with reference standard magnetic resonance imaging (MRI) for detecting HT.

Area postrema syndrome caused by medullary infarction
In the present study, we report a case of persistent intractable nausea and vomiting after a medullary infarction. Area postrema syndrome due to ischemic stroke is very rare. In this case, brain magnetic resonance imaging revealed an ischemic lesion in the lateral medulla extending caudally and dorsomedially. The patient presented with sustained nausea, vomiting, and poor oral intake over one month after the index stroke, even after resolution of dizziness and disappearance of nystagmus. She did not respond to intravenous metoclopramide with ondansetron.

Retinal and optic nerve magnetic resonance diffusion-weighted imaging in acute non-arteritic central retinal artery occlusion
Diffusion weighted imaging hyperintensity (DWI-H) has been described in the retina and optic nerve during acute central retinal artery occlusion (CRAO). We aimed to determine whether DWI-H can be accurately identified on standard brain magnetic resonance imaging (MRI) in non-arteritic CRAO patients at two tertiary academic centers.

Infratentorial developmental venous anomaly concurrent with a cavernoma and dural arteriovenous fistula
A 32-year-old woman underwent a head computed tomography scan after a traffic accident. A calcification in the left cerebellar hemisphere was disclosed. She did not complain of any symptoms, but neurological examination revealed cerebellar ataxia. She did not have any preceding episodes since birth, such as acute-onset headache. Magnetic resonance imaging showed past hemorrhage of the calcification lesion suggestive of a cerebellar cavernoma. A dilated vascular structure was also observed (Fig. 1A, B).

Quantitative Analysis of White Matter Hyperintensity: Comparison of Magnetic Resonance Imaging Image Analysis Software
White matter hyperintensity (WMH), defined as abnormal signals on magnetic resonance imaging (MRI), is an important clinical indicator of aging and dementia. Although MRI image analysis software can automatically detect WMH, the quantitative accuracy of periventricular hyperintensity (PVH) and deep white matter hyperintensity (DWMH) is unknown.
