Peak Systolic Velocity Measured by Continuous-Wave Doppler Ultrasonography without Angle Correction in Patients with Internal Carotid Artery Stenosis
Peak systolic velocity (PSV) is measured with pulse-wave (PW) Doppler with angle correction in patients with internal carotid artery stenosis (ICAS). However, the correlation between conventional angiography and PSV shows considerable scattering. We hypothesized that measuring PSV without angle correction would lead to better inter-rater reliability. This hypothesis was tested using a sector probe and continuous-wave (CW) Doppler without angle correction.

Cervical Posterior Spinal Artery Syndrome: A Case Report and Literature Review
We report a case of left upper cervical posterior spinal artery (PSA) syndrome caused by atherosclerosis of the left vertebral artery. A 70-year-old female experienced sudden dizziness and paralysis of the left upper and lower limbs. Diffusion-weighted magnetic resonance imaging (DWI) of the brain showed high signal intensity at the vermis and lower left hemisphere of the cerebellum, and magnetic resonance angiography showed that the entire left vertebral artery was thin. The patient was treated with an intravenous infusion of tissue plasminogen activator 2 hours after symptom onset and made a full recovery.

Moyamoya Vessel Pathology Imaged by Ultra–High-Field Magnetic Resonance Imaging at 7.0 T
Prompt diagnosis of vessel pathology and appropriate treatment of moyamoya vasculopathy (MMV) are essential to improve long-term prognosis. The aims of our study were to explore the diagnostic value of ultra–high-field (UHF) magnetic resonance imaging at 7.0 T in MMV patients and to compare the applicability of two different 7.0 T vessel imaging modalities to 3.0 T magnetic resonance angiography (MRA) and digital subtraction angiography (DSA).

Concurrence of Aneurysmal Subarachnoid Hemorrhage and Stanford Type A Acute Aortic Dissection
We report a rare case of concurrent aneurysmal subarachnoid hemorrhage (SAH) and acute aortic dissection (AAD). A 38-year-old man visited our hospital complaining of severe headache, and brain computed tomography (CT) revealed the presence of SAH. Thoracic to neck computed tomography angiography (CTA), performed in addition to brain CTA, suggested a tear in the aortic arch, and subsequent CT aortography established the diagnosis of Stanford type A AAD. The AAD in our patient, who reported no episodes of chest or back pain, was detected incidentally by thoracic to neck CTA.

Stenting for Internal Carotid Artery Stenosis Associated with Persistent Primitive Hypoglossal Artery Using Proximal Flow Blockade and Distal Protection System: A Technical Case Report and Literature Review
We report a very rare case of internal carotid artery (ICA) stenosis associated with persistent primitive hypoglossal artery (PPHA) treated by stenting using a proximal flow blockade and distal filter protection system. A 77-year-old man with a medical history of repeated cerebral infarction was referred to our hospital for treatment of progressive ICA stenosis. Cerebral angiography revealed that the degree of stenosis was 50% and the PPHA branched just distal to the stenosis at the C2 vertebral level.

Subarachnoid Hemorrhage due to Spinal Cord Schwannoma Presenting Findings Mimicking Meningitis
We report an unusual case of spinal SAH mimicking meningitis with normal brain computed tomography (CT)/magnetic resonance imaging (MRI) and negative CT angiography. Cerebrospinal fluid examination results were consistent with the manifestation of SAH. Spinal MRI performed subsequently showed an intradural extramedullary mass. The patient received surgery and was finally diagnosed with spinal cord schwannoma.

Four-Dimensional Computed Tomography Angiography Demonstrating a Ruptured Basilar Artery Aneurysm Causing Anterior Cerebral Circulation Arrest
A 61-year-old woman suffered a pronounced subarachnoid hemorrhage. Conventional computed tomography angiography (CTA) showed no enhancement of the intracranial vasculature, whereas there was normal contrast enhancement of bilateral external carotid artery branches. Subsequent four-dimensional computed tomography angiography (4D-CTA) demonstrated active contrast leakage out of a ruptured basilar tip aneurysm, whereas there was no enhancement of the anterior circulation at any time point, consistent with intracranial anterior circulation arrest.

Arterial Spin-Labeling Magnetic Resonance Perfusion Imaging with Dual Postlabeling Delay in Internal Carotid Artery Steno-occlusion: Validation with Digital Subtraction Angiography
Arterial spin-labeling magnetic resonance perfusion imaging (ASL-MRI) allows noninvasive measurement of cerebral blood flow (CBF) but depends on the arterial transit time (ATT). With the commonly used single postlabeling delay (PLD) of 1.5 seconds, slow flow through collateral vessels may be underestimated. We used both 1.5 and 2.5 seconds to overcome this problem. We validated these PLD settings by measuring the ATT and identifying the angiographic circulation using digital subtraction angiography (DSA).

Significant Association of the RNF213 p.R4810K Polymorphism with Quasi-Moyamoya Disease
Quasi-moyamoya disease is an angiographical moyamoya disease equivalent accompanied by known underlying diseases. Mysterin/RNF213 is a major susceptibility gene for moyamoya disease, of which the p.R4810K variant is a founder polymorphism. The genetics of quasi-moyamoya disease is poorly understood, therefore, this study investigated a potential association between the p.R4810K polymorphism and quasi-moyamoya disease.

Clinical Outcome Predicted by Collaterals Depends on Technical Success of Mechanical Thrombectomy in Middle Cerebral Artery Occlusion
This study aimed to analyze the effects of technical outcome of mechanical thrombectomy (MTE) on the associations between collateral status, assessed with pretreatment computed tomography angiography (CTA), and neurological and functional outcome, as well as associations between collaterals and metabolic risk factors (arterial hypertension, diabetes, hyperlipidemia, overweight).

Utility of Urgent Computed Tomography Angiography in the Setting of Intraparenchymal Brain Hemorrhage
Patients presenting with an intracerebral hemorrhage (ICH) generally have an initial noncontrast computed tomography (NCCT) of the brain. Computed tomography angiography (CTA) can help identify secondary causes of ICH and detect a “spot sign.” We hypothesized that performing an urgent CTA in the setting of a presumed primary ICH has only limited utility and did not alter urgent management.

Neutrophil-to-Lymphocyte Ratio Correlates with Severity of Extracranial Carotid Stenosis —A Study Using Digital Subtraction Angiography
Although neutrophil-to-lymphocyte ratio (NLR) has been reported to correlate with subclinical atherosclerosis, little is known about the relationship between NLR and carotid stenosis.
