      AIMS: The purpose of this study was to evaluate the clinical impact of addition of [(11)C]Pittsburgh compound-B positron emission tomography ((11)C-PiB PET) on routine clinical diagnosis of Alzheimer's disease (AD) dementia and mild cognitive impairment (MCI), and to assess diagnostic agreement between clinical criteria and research criteria of the National Institute on Aging-Alzheimer's Association.

      METHODS: The diagnosis in 85 patients was made according to clinical criteria. Imaging ...

      In multiple system atrophy with predominant parkinsonism (MSA-P), several voxel-based morphometry (VBM) studies have revealed gray matter loss; however, the white matter volume changes have been rarely reported. We investigated the volume changes of white matter as well as gray matter by VBM. A retrospective MRI study was performed in 20 patients with MSA-P and 30 age-matched healthy controls. We applied VBM with statistical parametric mapping (SPM8) plus diffeomorphic anatomical ...

      Static encephalopathy of childhood with neurodegeneration in adulthood (SENDA) is a recently established disorder that is a subtype of neurodegeneration with brain iron accumulation (NBIA). We presented the first case report of SENDA of a 39-year-old female. She had psychomotor retardation from childhood and remained static for two decades. Then, at the age of 30, she developed severe dystonia and parkinsonism. Brain MRI revealed T2-weighted hypointensity signal in the globus pallidus ...

      IntroductionOur aim was to determine diffusion abnormalities in the uncinate fasciculus (UF) in Alzheimer’s disease (AD) by diffusion tensor tractography (DTT) using a new method for measuring the core of the tract.MethodsWe studied 19 patients with AD and 19 age-matched control subjects who underwent MRI using diffusion tensor imaging (DTI). DTT of the UF was generated. The mean diffusivity (MD) and fractional anisotropy (FA) of the core of the tract were measured after voxelized tract ...

      BACKGROUND: Parkinson's disease (PD) is occasionally complicated by camptocormia. In a previous study, we classified camptocormia into upper and lower types based on the inflection point, and reported that lidocaine injection into the external oblique muscle, but not into the internal oblique or rectus abdomen, improved upper camptocormia in PD. The effect of a single lidocaine injection disappeared over a period of few days. In this study, we used repeated lidocaine injections into the ...

      BACKGROUND AND PURPOSE: Patients with agenesis of the corpus callosum (AgCC) exhibit cognitive and behavioral impairments that are not replicated by surgical transection of the callosum, suggesting that other anatomic changes may contribute to the observed clinical findings. The purpose of this study was to determine whether the ventral cingulum bundle (VCB) is affected in patients with AgCC by using diffusion tensor imaging (DTI) and volumetry.

      MATERIALS AND METHODS: Twelve participants ...

      The purpose of this study was to determine correlations among disease progression, diffusion abnormalities in the posterior cingulum and hippocampal volume in patients with Alzheimer's disease (AD). We studied 25 AD patients by neuropsychological testing, including the Mini-Mental State Examination (MMSE), and by magnetic resonance imaging, including diffusion tensor imaging (DTI) and high-resolution three-dimensional T1-weighted imaging. The MMSE score was used as an indicator of ...

      BACKGROUND AND PURPOSE: In hemimegalencephaly, MR imaging often reveals midsagittal bandlike structures between the 2 lateral ventricles. To determine whether these structures are aberrant midsagittal fibers, we retrospectively reviewed them on conventional MR imaging and prospectively examined them by diffusion tensor MR and fiber tract (FT) reconstruction imaging.

      MATERIALS AND METHODS: We retrospectively reviewed conventional MR images of 26 consecutive patients with ...

      BACKGROUND: Although schizophrenia and major depressive disorder (MDD) differ on a variety of neuroanatomical measures, a diagnostic tool to discriminate these disorders has not yet been established. We tried to identify structural changes of the brain that best discriminate between schizophrenia and MDD on the basis of gray matter volume, ventricle volume, and diffusion tensor imaging (DTI).

      METHOD: The first exploration sample consisted of 25 female patients with schizophrenia and 25 ...

      Arterial spin labeling (ASL) is a noninvasive technique that can measure cerebral blood flow (CBF). To our knowledge, there is no study that examined regional CBF of multiple sclerosis (MS) patients by using this technique. The present study assessed the relationship between clinical presentations and functional imaging data in MS using pseudocontinuous arterial spin labeling (pCASL). Twenty-seven patients with MS and 24 healthy volunteers underwent magnetic resonance imaging and pCASL ...

      OBJECTIVE: The association between amygdala enlargement (AE) and temporal lobe epilepsy (TLE) has increasingly been reported. However, the pathology of AE remains poorly understood. The purpose of this study was to explore AE pathology using (11)C-methionine (Met) positron emission tomography (PET)/computed tomography (CT) in patients who have TLE with AE.

      MATERIALS AND METHODS: Twenty-six TLE patients with AE and 18 TLE patients without AE underwent (11)C-Met PET/CT and magnetic ...

      BACKGROUND AND PURPOSE: Hemimegalencephaly is a rare but well-known congenital malformation with ipsilateral enlargement of the hemicerebrum. However, very little is known about changes in structures outside the involved hemisphere in patients with this condition. We investigated morphologic abnormalities occurring outside the affected hemisphere by MR imaging in a large series of patients with hemimegalencephaly.

      IntroductionThe uncinate fasciculus (UF) consists of core fibers connecting the frontal and temporal lobes and is considered to be related to cognitive/behavioral function. Using diffusion tensor tractography, we quantitatively evaluated changes in fractional anisotropy (FA) and the apparent diffusion coefficient (ADC) of the UF by tract-specific analysis to evaluate the damage of the UF in patients with amyotrophic lateral sclerosis (ALS).MethodsWe obtained diffusion tensor images of 15 ...
