Characteristics of Intracranial Aneurysms According to Levels of Coronary Artery Calcium

Bang‐Hoon Cho, Ji Hwa Kim, Sang Hyun Suh, Su Jung Baik et autres

Background and Purpose- Several vascular risk factors are known to be associated with the occurrence of intracranial aneurysms (IAs). Coronary artery calcium (CAC), which reflects the atherosclerotic burden of the coronary arteries, is a known predictor of cardiovascular events and stroke. We …

Abstract TP220: Neutrophil Gelatinase-associated Lipocalin in Patients With Acute Ischemic Stroke

Ji Hwa Kim, Sang Won Han, Seong Hwan Ahn, Kyung‐Yul Lee

Introduction: Neutrophil gelatinase-associated lipocalin (NGAL) appears to be a promising biomarker in diagnosis and prognosis in kidney and cardiovascular disease. However, the relationship between NGAL concentration and ischemic stroke is poorly understood. Hypothesis: We investigated plasma NGAL concentration in patients with acute …

Abstract TP223: Mechanisms of Lateral Medullary Infarction Based on Combined MR Diffusion/Perfusion Imaging Patterns

Young‐gun Lee, Ji Hwa Kim, Kyung‐Yul Lee

Introduction: Steno-occlusive lesion in vertebral artery and posterior inferior cerebellar artery (PICA) or perforator occlusion could result in lateral medullary infarction. However, exact mechanism of lateral medullary infarction is not straightforward due to limited information from MR angiography (MRA) and variations of …

Correlation between Hyperintense Vessels on FLAIR Imaging and Arterial Circulation Time on Cerebral Angiography

Seung Ha Lee, Kwon–Duk Seo, Ji Hwa Kim, Sang Hyun Suh et autres

PURPOSE: Hyperintense vessels (HVs) on fluid-attenuated inversion recovery (FLAIR) imaging are associated with the leptomeningeal collateral circulation in cases of arterial occlusive lesions. Nevertheless, the relationship between HVs on FLAIR imaging and arterial circulation time (ACT) on cerebral angiography has not been …
