AbstractCerebral amyloid angiopathy-related inflammation is a syndrome of reversible encephalopathy with cerebral amyloid angiopathy, however the pathology is not well understood. We clear a part of the pathology through the first case of an 80-year-old man with cerebral amyloid angiopathy-related inflammation induced by relapsing polychondritis (RP) analysis. An 80-year-old man was diagnosed with RP by auricular cartilage biopsy. Almost no abnormality including intracranial microbleeding was detected by cranial magnetic resonance image (MRI) at diagnosis. However, he developed a headache and hallucination after five month...

Abstract PET and SPECT provide us with information about biological quantitative values at localized area, even at the deep component of human. They usually have been used for diagnosis, but when combining with radiotherapy, PET and SPECT images would be helpful to make a decision on radiation-dose distribution for treatment because the patient images can be obtained in the similar condition under radiation therapy. In addition, anti-tumor effect of radiation therapy is now precisely controlled for target. Therefore, precise information of tumor, such as extent of tumor and heterogeneity within tumor, would make t...

Abstract OBJECTIVE: The microstructural integrity of gray and white matter is decreased in adult moyamoya disease, suggesting covert ischemic injury as a mechanism of cognitive dysfunction. Establishing a microstructural brain imaging marker is critical for monitoring cognitive outcomes following surgical interventions. The authors of the present study determined the pathophysiological basis of altered microstructural brain injury in relation to advanced arterial occlusion, cerebral hypoperfusion, and cognitive function. METHODS: The authors examined 58 patients without apparent brain lesions and 30 healthy c...

AbstractTransient ischemic dilation (TID), a marker of severe coronary artery disease (CAD), is the post-stress to rest left ventricular (LV) volume ratio quantified using non ECG gated single photon emission computerized tomography (SPECT). Although prone positioning causes physiological reduction of LV volume in normal subjects, we hypothesize this may not occur in TID with underlying severe CAD as cardiac hemodynamics worsen when prone. We aim to evaluate the utility of the non ECG gated supine to prone LV volume ratio (SPLVr) for identifying severe CAD. Retrospective data analysis from 130 patients with TID ratio &thin...

AbstractBackground Left ventricular contraction dyssynchrony (LVCD) has been related to induced ischemia and transmural scar but the interplay of myocardial viability and dyssynchrony is unknown. The aim of the present study was to establish the role of dyssynchrony in the context of a viability study performed with nitrate augmentation gated single photon emission computed tomography (GSPECT) myocardial perfusion imaging (MPI).Methods Fifty-four consecutive patients with ischemic dilated cardiomyopathy (IDC) and depressed left ventricular ejection fraction (LVEF) were included. They underwent a two-day rest/nitroglyce...

This article describes the methodology of such integration, focusing on integration of MEG. Also discussed is the clinical value of integration of MEG, in terms of planning of intracranial EEG implantation, interpretation of intracranial EEG data, planning of final resection, and addressing surgical failures.
