UNLABELLED The efficacy of cerebral arterial bypass surgery was assessed on brain perfusion SPECT using statistical parametric mapping (SPM) and a probabilistic brain atlas. METHODS Fifteen patients with ischemia in the internal carotid artery (ICA) territory and 21 age-matched healthy volunteers were enrolled. (99m)Tc-HMPAO basal/acetazolamide brain(More)
OBJECTIVE To determine the ictal focus and the role of seizure characteristics, fluorodeoxyglucose (FDG) PET, and subtraction ictal SPECT in patients diagnosed as having nonlesional lateral temporal lobe epilepsy by long-term scalp video-EEG monitoring. METHODS The authors studied 33 consecutive patients with nonlesional neocortical epilepsy who had a(More)
INTRODUCTION The purpose of this work was to quantitatively evaluate the hemodynamic changes after carotid artery stenting (CAS) by measuring cerebral blood flow (CBF) using arterial spin labeling (ASL). METHODS Twenty sets of pre- and postprocedural CBF maps were acquired using ASL in patients who underwent CAS. Vascular territory- and anatomical(More)
UNLABELLED Although several prognostic factors are used to predict recurrence and to select adequate candidates for liver transplantation for hepatocellular carcinoma (HCC), these prognostic factors have some clinical limitations. The purpose of this study was to evaluate (18)F-FDG PET as a prognostic factor and to optimize its ability to predict tumor(More)
PURPOSE The new modality of an integrated positron emission tomography/magnetic resonance imaging (PET/MRI) has recently been introduced but not validated. Our objective was to evaluate clinical performance of (18)F-fluoro-2-deoxyglucose ((18)F-FDG) PET/MRI in patients with head and neck cancer. METHODS This retrospective study was conducted between(More)
Although the clinical manifestations such as drowsiness, brisk reflexes, extensor plantar responses and hemisensory disturbance usually are considered to suggest Bickerstaff's brainstem encephalitis (BBE) rather than Miller Fisher syndrome (MFS), the nosological relationship between BBE and MFS has yet to be established. Herein, we report upon a 58-year-old(More)
BACKGROUND AND PURPOSE The surgical outcomes of adult moyamoya disease are rarely reported. We aimed to evaluate the long-term outcomes of combined revascularization surgery in patients with adult moyamoya disease. METHODS Combined revascularization surgery consisting of superficial temporal artery-middle cerebral artery anastomosis with(More)
In medical research and practice, imaging is now playing a crucial role. With rapidly developing molecular imaging, the role of in vivo imaging is expected to expand much more. In molecular imaging, one of the recent trends is multimodal imaging, which theoretically combines all the strengths of each imaging modality and consequently provides synergism. For(More)
Germinoma in the basal ganglia (BG) is notorious for its diagnostic difficulty. Clinical and radiological features of this disease are quite diverse, but have not been well characterized with respect to prognosis. We retrospectively reviewed the clinical course and treatment outcomes of 17 patients with a BG germinoma. The initial magnetic resonance imaging(More)
Atherosclerosis is an inflammatory disease as well as a lipid disorder. Atherosclerotic plaque formed in vessel walls may cause ischemia, and the rupture of vulnerable plaque may result in fatal events, like myocardial infarction or stroke. Because morphological imaging has limitations in diagnosing vulnerable plaque, molecular imaging has been developed,(More)
