The impact of electroconvulsive therapy (ECT) on the regional cerebral blood flow (rCBF) abnormalities in late-life depression is still unknown and the clinical significance of these findings in late-life depression has not been fully discussed. Using single photon emission computed tomography (SPECT) with 99mTc-hexamethylpropylene amine oxime(More)
Infective abdominal aortic aneurysm (IAAA) is relatively rare, but a case which is caused by Haemophilus influenzae type B is very rare. We experienced one IAAA case due to H. influenzae type B. The patient was 69-year-old man presenting with severe abdominal and back pain and elevated C-reactive protein (CRP), as inflammatory marker. The patient was found(More)
We have developed an analysis system for photocatalytic reactions, which utilizes a TiO(2) immobilized micro-capillary and a detection technique for dye concentration at arbitrary positions. In this study, we investigated the reaction processes for the photocatalytic decomposition of rhodamine 6G. This system allows the distinction of direct and secondary(More)
BACKGROUND The architecture of the arterial wall affected with Buerger's disease has been known to be preserved in all three layers, while the one affected by arteriosclerosis obliterans (ASO) is degenerated and destroyed. We analyzed affected arteries with immunohistochemical methods to clarify the differences between Buerger's disease and ASO. MATERIALS(More)
OBJECTIVE To study whether the actual radiation exposure is different between computed tomography (CT) scanners and medical centers when the same patient is scanned, we investigated the actual effective doses for a whole body (Chest-Pelvis) CT scan in a multicenter study. MATERIALS AND METHODS Data from subjects were collected using 12 CT scanners at six(More)
INTRODUCTION Using a high-pitch dual-source CT (DSCT), we aimed to quantify the amounts of contrast media, radiation doses, and image qualities in patients undergoing pulmonary vein (PV) isolation. METHODS AND RESULTS The study enrolled 60 patients who were randomly assigned in a 1: 1: 1 ratio to undergo ECG-gated 64-slice multidetector computed(More)
