Previous studies of brain single-photon emission tomography (SPECT) showed changes of regional cerebral blood flow (rCBF) in migraineurs during prodromes or headache attacks. Little is known about how successful medication of migraine prevention can reflect rCBF in migraineurs. We highlighted alternation of brain SPECT findings in a migraineur with aura before and after prophylactic treatment w...
AIMS Although there have been no conclusive pathophysiological findings in support of the degeneration theory in the etiology of schizophrenia to date, results of our neuroimaging studies suggest functional changes in the brains of schizophrenics. We evaluated age-related changes of brain perfusion in medicated patients with schizophrenia. METHOD In this study, we evaluated age-related change...
The prefrontal cortex is asymmetric in both structure and function. In normal subjects, the right prefrontal cortex is activated more than the left during response inhibition. Patients with attention deficit hyperactivity disorder (ADHD) have impaired response inhibition and altered structural interhemispheric asymmetry. This study was conducted to examine the functional interhemispheric asymme...
A 47-year-old man presented with carotid rete mirabile manifesting as subarachnoid hemorrhage (SAH). Computed tomography showed SAH, and angiography disclosed an abnormal vascular network around the petrous and cavernous portions of the internal carotid artery. Single photon emission computed tomography (SPECT) with technetium-99m methyl cysteinate dimer revealed reduced regional cerebral blood...
BACKGROUND It remains to be elucidated whether brain activity is altered in takotsubo cardiomyopathy. METHODS AND RESULTS We measured cerebral blood flow (CBF) in 3 consecutive patients with takotsubo cardiomyopathy using (99m)Tc ethyl cysteinate dimmer single photon-emission computed tomography (SPECT) in the acute and chronic phases. In all patients, CBF was significantly increased in the h...
The purpose of this study was to investigate the associations between regional cerebral blood flow (rCBF) and cognitive function in patients having a local stroke within the thalamus or putamen. The Mini-Mental State Examination(MMSE)and the Kohs Block Design Test(KBDT) were used to evaluate cognitive function. Brain single-photon emission computed tomography (SPECT)was performed with Tc-ethyl ...
To investigate over time changes in striatal dopamine transporter (DAT), we performed two sequential N-omega-fluoropropyl-2beta-carbomethoxy-3beta-(4-iodophenyl) tropane single photon computed tomography (SPECT) scans in 20 subjects with essential tremor (ET), in 13 with Parkinson disease (PD) and in 23 healthy controls (HC, one scan only). We also performed an [(99m)Tc]ethyl cysteinate dimer b...
BACKGROUND Patients with aluminum hydroxide adjuvant-induced macrophagic myofasciitis (MMF) complain of arthromyalgias, chronic fatigue and cognitive deficits. This study aimed to characterize brain perfusion in these patients. METHODS Brain perfusion SPECT was performed in 76 consecutive patients (aged 49±10 y) followed in the Garches-Necker-Mondor-Hendaye reference center for rare neuromusc...
