Introduction:Amphetamines are central nervous system (CNS) stimulant substances and amphetamine abuse is considered a growing problem in our country. Previous studies revealed destructive effects of amphetamines on metabolism, perfusion and structure of brain. The aim of current study was evaluating regional cerebral blood flow (rCBF) disturbances in methamphetamine (MA) abuser...

Brain single-photon emission computerized tomography (SPECT), in particular, with perfusion agents or with neuroreceptor imaging radiopharmaceuticals, is rapidly becoming a clinical tool in many neurologic and psychiatric conditions. This imaging modality has been used for diagnosis, prognosis assessment, evaluation of response to therapy, risk stratification, detection of benign vs. malignant ...

BACKGROUND AND PURPOSE Both cerebral hypoperfusion and vascular risk factors have been implicated in early aging of the brain and the development of neurodegenerative disease. However, the current knowledge of the importance of cardiovascular health on resting brain perfusion is limited. The aim of the present study was to elucidate the relation between brain perfusion variability and risk fact...

Moyamoya disease (MMD) is a cerebrovascular disorder involving stenosis of brain vessels. Brain perfusion SPECT in MMD demonstrates impaired perfusion in ischemic areas. We present a 6-year-old boy with MMD. The patient had numbness on the right arm and simultaneous electroencephalography changes while studying arms up on the table. To differentiate seizure and ischemic symptoms, brain perfusio...

post stroke dementia is one of the most common complications of stroke that is preventable and relatively treatable too. the purpose of the study is comparison between the positive findings in brain ct scan and brain perfusion spect. 15 patients who were complicated by dementia after cerebrovascular accident and also 5 patients as a control group enrolled in this study. brain ct scan and brain ...
