We simultaneously injected both internal carotid arteries (ICAs) during 3D rotational digital subtraction angiography in a patient with a ruptured anterior communicating artery (Acom) aneurysm and vasospasm. Shaded surface display (SSD) images from this acquisition provided more anatomic detail than did SSD images created from individual ICA 3D rotational digital subtraction angriography. In th...

Iterative combinatorial auctions (ICAs) are IT-based economic mechanisms where bidders submit bundle bids in a sequence and an auctioneer computes allocations and ask prices in each auction round. The literature in this field provides equilibrium analysis for ICAs with non-linear personalized prices under strong assumptions on bidders’ strategies. Linear pricing has performed very well in the l...

BACKGROUND AND PURPOSE Calcification of the intracranial vasculature is an independent risk factor for stroke. The relationship between luminal stenosis and calcium burden in the intracranial circulation is incompletely understood. We evaluated the relationship between atherosclerotic calcification and luminal stenosis in the intracranial ICAs. MATERIALS AND METHODS Using a prospective stroke...

BACKGROUND AND PURPOSE The distal dural ring (DDR) represents the anatomic border between the extradural and intradural internal carotid arteries (ICAs). The purpose of this study was to examine whether 3D-MR cisternography and MR angiography (MRA) fusion images can identify the boundary between the CSF and the cavernous sinus, which might represent the DDR. MATERIALS AND METHODS Thirty-six c...

To the Editor: A 36‐year‐old man with intermittent migraine‐like headache with aura for 20 years underwent cerebrovascular computed tomography angiography (CTA) revealing very small calibers of bilateral internal carotid arteries (ICAs) in other hospital. He was admitted to our hospital for further examination several days later. He had no vascular risk factors, and no family history of atheros...

Facebook is commonly used in the daily lives of higher-education students. Facebook groups are considered educational tools that can be used as learning management system (LMS) substitutes or supplements. However, the effect of using Facebook groups on learning in the computer engineering field has not been adequately compared with that of using other types of LMS and must be explored. The resu...

BACKGROUND AND PURPOSE The tortuous distal part of the ICA may have an attenuating effect on pulsatile arterial flow. We investigated local arterial blood flow patterns in the ICA proximal and distal to the carotid siphon to detect quantitative waveform changes. MATERIALS AND METHODS Arterial flow patterns were analyzed by using flow-sensitized 4D PC MR imaging (time-resolved 3D PCMR) at 3T i...
