Intracranial Vascular Calcification is Protective from Vasospasm after Aneurysmal Subarachnoid Hemorrhage
The objective of this study was to assess the association between intracranial calcification, a marker for atherosclerosis, and vasospasm. Charts and nonenhanced computed tomography scans of patients with subarachnoid hemorrhage were retrospectively reviewed. Transcranial Doppler studies were used to categorize vasospasm using mean flow velocity: mild vasospasm 120-199 cm/second and severe ≥200 cm/second.

Multidetector Computed Tomography Angiography to Detect the Cause of Multiple Brain Infarctions
Multidetector computed tomography angiography (MDCTA) is useful to inspect cardiovascular pathologic changes with minimal invasiveness. Here we evaluated the usefulness of MDCTA to determine the cause of acute multiple brain infarction (AMBI).

Cervical Spinal Epidural Arteriovenous Fistula with Coexisting Spinal Anterior Spinal Artery Aneurysm Presenting as Subarachnoid Hemorrhage—Case Report
Hemorrhagic presentation of spinal epidural arteriovenous fistulas (AVFs) is rare in patients with cervical spinal vascular lesions. The present report describes a patient with cervical spine epidural AVFs associated with anterior spinal artery aneurysm at the same vertebral level presenting with subarachnoid hemorrhage. A 54-year-old man presented with sudden onset of headache. Computed tomography of the head showed subarachnoid hemorrhage. Diagnostic angiography revealed an epidural AVF located at the C1-2 level that was fed mainly by the dorsal somatic branches of the segmental arteries from the radicular artery and anterior spinal artery.

The Radical Scavenger Edaravone Improves Neurologic Function and Perihematomal Glucose Metabolism after Acute Intracerebral Hemorrhage
Oxidative injury caused by reactive oxygen species plays an important role in the progression of intracerebral hemorrhage (ICH)-induced secondary brain injury. Previous studies have demonstrated that the free radical scavenger edaravone may prevent neuronal injury and brain edema after ICH. However, the influence of edaravone on cerebral metabolism in the early stages after ICH and the underlying mechanism have not been fully investigated. In the present study, we investigated the effect of edaravone on perihematomal glucose metabolism using 18F-fluorordeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT).

Parkinsonism after External Ventricular Drainage in a Patient with Intraventricular Hemorrhage
We report a patient who presented with Parkinsonism after external ventricular drainage (EVD) for an intraventricular hemorrhage (IVH). We also demonstrate dopaminergic system dysfunction using 18F-florinated-N-3-fluoropropyl-2-β-carboxymethoxy-3-β-(4-lodophenyl) nortropane (18F-FP-CIT) positron emission tomography (PET) scanning. A 50-year-old woman presented with manifestations of Parkinsonism, including severe rigidity and 3-Hz resting tremor, immediately after EVD for IVH. 18F-FP-CIT PET images at 6 months after onset showed dysfunction of the bilateral caudate nuclei and putamen after EVD that seemed to have induce...

Comparison of Cerebral Blood Flow Data Obtained by Computed Tomography (CT) Perfusion with that Obtained by Xenon CT Using 320-Row CT
In this study, we have compared CBF ratios as well as CBF values obtained from CTP–CBF data to those obtained from XeCT–CBF data for the same patients to determine CTP–CBF parameters that can be used for interpatient comparisons.

Primary Pontine Hemorrhage in the Acute Stage: Clinical Features and a Proposed New Simple Scoring System
It is important to evaluate the likelihood of fatality in patients with acute primary pontine hemorrhage (PPH) in emergency departments. We aimed to evaluate the clinical symptoms and computed tomography findings of PPH to develop a simple grading scale for predicting the mortality of PPH.

Detection of Basilar Artery Dissection by Ultrasound
We report a case of a 45-year-old woman with unusual headache 1 week before admission. After cerebrovascular ultrasound, a basilar artery dissection was supposed despite the normal neurologic, cerebrospinal fluid, and computed tomography findings. On a follow-up color-coded duplex sonography (1 month after the onset), reperfusion was detected in the vertebral and basilar arteries, but residual high-grade stenosis of the basilar artery was also present.

Prediction of Cerebrovascular Reserve Capacity by Computed Tomography Perfusion Using 320-Row Computed Tomography
Acetazolamide loading has been the “gold standard” for evaluating cerebrovascular reserve capacity (CVRC). However, life-threatening side effects of acetazolamide have recently been reported. The aim of the study was to identify alternative methods for evaluating CVRC.

Computed Tomography–Verified Leukoaraiosis Is a Risk Factor for Post-thrombolytic Hemorrhage

Dissecting Aneurysm of Anterior Inferior Cerebellar Artery Initially Presenting with Nonhemorrhagic Symptom
We report a patient with a probable dissecting aneurysm of the anterior inferior cerebellar artery (AICA) initially presenting with a nonhemorrhagic symptom, which resulted in subarachnoid hemorrhage. A 61-year-old woman suddenly experienced nausea. Computed tomography (CT) on admission showed a high-density mass with a double lumen in the right cerebellopontine angle without subarachnoid hemorrhage. Five days after the onset, she suddenly lost consciousness. CT demonstrated subarachnoid hemorrhage.

The Circle of Willis and White Matter Lesions in Patients with Carotid Atherosclerosis
The correlation between cerebral atherosclerosis and white matter lesions (WMLs) in the elderly was controversial in the published articles, where the stenosis was often evaluated by ultrasonography, computed tomography angiography, or magnetic resonance angiography and collaterals were seldom considered. We hypothesized that collaterals influence WMLs. Our study was to explore the relationship between the circle of Willis and WMLs in a retrospective, hospital-based cohort of patients with carotid atherosclerosis.

Conventional Computed Tomography and Axial Magnetic Resonance T2-Weighted Imaging of Horizontal Segment of Middle Cerebral Artery in Moyamoya Disease or Syndrome in Adult Patients
Moyamoya disease or syndrome (MMD or MMS) is a cerebrovascular disease characterized by stenosis or occlusion of the distal portion of the internal carotid arteries, with ultimate spread to the proximal portion of the anterior cerebral arteries and middle cerebral arteries (MCAs). In the present study, we wanted to evaluate the usefulness of conventional computed tomography (CT) and axial magnetic resonance (MR) T2-weighted imaging (T2WI) for the examination of horizontal segments of the MCAs (ie, M1 segments) in patients diagnosed with MMD or MMS.
