BACKGROUND AND PURPOSE ADC provides a measure of water molecule diffusion in tissue. The aim of this study was to evaluate whether the fractional change in ADC during therapy can be used as a valid predictive indicator of treatment response in head and neck squamous cell carcinoma treated with chemoradiotherapy. MATERIALS AND METHODS Forty patients(More)
OBJECTIVE Basilar arterial (BA) dolichoectasia is associated with cerebral small-vessel disease and stroke. However, the association between moderate dilation of the BA and cerebral small-vessel disease or subsequent cardiovascular events remains unclear. This study aims to clarify the factors related to BA diameter and to clarify whether the BA diameter is(More)
OBJECTIVE Hemorrhagic risk is unknown in patients with moyamoya-like vessels associated with atherosclerotic intracranial cerebral artery occlusion. This study was undertaken to investigate the association between moyamoya-like vessels and cerebral microbleeds (CMBs) in patients with atherosclerotic steno-occlusive disease. METHODS The study population(More)
BACKGROUND AND PURPOSE Limited information is available on the long-term effects of interleukin-6 (IL-6) on systemic atherosclerosis. The purpose of the present study was to clarify the relationship between chronic elevation of IL-6 and the long-term progression of carotid atherosclerosis. METHODS We prospectively evaluated 210 patients with ≥1 vascular(More)
OBJECTIVE To determine whether chronic kidney disease (CKD) is associated with incident dementia independent of cerebral small-vessel disease (SVD) in patients with vascular risk factors. METHODS Using data from a Japanese cohort of participants with vascular risk factors in an ongoing observational study from 2001, we evaluated the association between(More)
INTRODUCTION The aim of this study was to examine the association between mild parkinsonian signs (MPS), cerebral small-vessel disease (SVD), and total SVD burden in patients with vascular risk factors. METHODS We performed a cross-sectional study among 268 patients with vascular risk factors but without parkinsonism or dementia (71.0 ± 7.8 years, 63%(More)
OBJECTIVE The objective of this study was to examine the association of inflammatory markers with risk of first-ever cerebrovascular events (CVEs), while simultaneously evaluating subclinical vascular disease. METHODS AND RESULTS We enrolled 464 outpatients who had vascular risk factors without any preexisting cardiovascular disease. We examined the(More)
BACKGROUND AND PURPOSE Cerebral microbleeds (CMB) are observed in the elderly and have been regarded as one of the manifestations of small vessel disease. Although inflammatory processes have attracted much attention not only in large-artery disease, but also in small vessel disease, their involvement in CMB remains to be determined. The purpose of this(More)
BACKGROUND Both silent cerebral infarction (SCI) and carotid intima-media thickness (IMT) are associated with future stroke. We evaluated whether SCI could be a predictor for incident stroke independent of carotid IMT in high-risk patients. METHODS We performed a prospective cohort study among 282 outpatients who had one or more atherosclerotic risk(More)
Chronic kidney disease is an independent risk factor for cardiovascular disease. The association between carotid intima-media thickness (IMT) and chronic kidney disease is controversial, however. In addition, whether renal dysfunction promotes vascular calcification in patients with chronic kidney disease is not clear. The study subjects were 1003 patients(More)
