UNLABELLED The purpose of this study is to clarify the changes of hippocampal perfusion in neuropsychiatric diseases, including dementia, compared with control subjects, and to correlate hippocampal perfusion with the dementia rating scale and the severity of memory disturbance in patients with these diseases. METHODS A total of 45 right-handed patients(More)
UNLABELLED (123)I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy is a useful tool for differentiating idiopathic Parkinson's disease (PD) from parkinsonism (PS) caused by other disorders. However, cardiac MIBG uptake is affected by various causes. Alternatively, hypoperfusion in the occipital lobe of PD is reported recently. OBJECTIVE The(More)
UNLABELLED The aim of this study was to review the etiology of CCD and study factors that affect the development and manifestation of CCD. METHODS Three hundred and eleven patients with supratentorial lesions were evaluated for the presence of CCD with SPECT and 123I-IMP. In representative cases, continuous arterial blood sampling was done and rCBF was(More)
Sympathetic stimulation of the Müller muscle may be responsible for most of the medically reversible cases of eyelid retraction in patients with Graves disease. The authors studied 21 patients with class I Graves ophthalmopathy (GO), 32 patients with Graves disease without ophthalmopathy (GD), and 12 control subjects. T1-weighted spin-echo magnetic(More)
UNLABELLED PET with 13N-ammonia permits the noninvasive quantification of myocardial blood flow (MBF) in humans. The present study was done to assess the reproducibility of quantitative blood flow measurements at rest and during pharmacologically induced hyperemia in healthy individuals. METHODS Thirty healthy volunteers (26 men, 4 women) were studied.(More)
PURPOSE To assess the role of positron emission tomography-computed tomography (PET-CT) and multidetector-row CT (MD-CT) in detecting the primary lesion and lymph node metastasis in patients with colorectal cancers. METHODS A collective total of 80 lesions resected from 77 patients were examined pathologically. We analyzed the significance of the(More)
BACKGROUND Chronic pain is defined as intractable pain caused by abnormal pain transmission or impairment of the pain control system per se. Alteration of regional cerebral blood flow (rCBF) is known to occur under the presence of pain stimulation. Epidural spinal cord stimulation (SCS) is occasionally effective in relieving the symptom. OBJECTIVE The aim(More)
The aim of this study was to evaluate the efficacy and role of technetium-99m tetrofosmin for the detection of abnormal parathyroid glands to be referred for surgical treatment. Twenty-eight consecutive patients, including 25 primary and 3 secondary cases of hyperparathyroidism, were evaluated. (99m)Tc-tetrofosmin/(99m)Tc-pertechnetate subtraction(More)
BACKGROUND 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy is a useful tool for diagnosing cardiac autonomic neuropathy (CAN) in non-insulin-dependent diabetes mellitus (NIDDM). However, the long-term prognostic value for cardiac events or mortality in NIDDM has not been clarified. METHODS AND RESULTS We investigated the long-term prognostic(More)
BACKGROUND The deep-inspiration breath-hold F-fluorodeoxyglucose PET/computed tomography (DIBH F-FDG PET/CT) technique improves the limitations of diagnosing a lesion located in an area influenced by respiratory motion that brings about spatial misregistration caused by respiration between PET and CT. However, its clinical effectiveness with regard to(More)
