Objective: The aim of this study was to evaluate the influences of reconstruction and attenuation correction on the differences in the radioactivity distributions in 123I brain SPECT obtained by the hybrid SPECT/CT device. Methods: We used the 3-dimensional (3D) brain phantom, which imitates the precise structure of gray mater, white matter and bone regions. It was filled with 123I solution (20...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Background and purpose: Autism spectrum disorder (ASD) is a psychiatric disorder which occurs in early years of life and causes various individual and social problems. Early detection of autism would help in taking necessary precautions and preventing its adverse side effects. Methods & Materials: In this paper, we reviewed the articles that have investigated brain structural changes caused by...
Abstract Background: Stroke is the second leading cause of death in the world and has irreversible consequences. Cerebral ischemia/reperfusion (I/R) through production of oxidants and inflammatory markers causes apoptosis of brain neurons. On the other hand, in various studies, the antioxidant and anti-inflammatory effects of the Malva neglecta have been proven. Therefore, in this study, we inv...
Brain foreign bodies and penetrating missile injuries of the brain are familiar topics for Iranian physicians, especially after Iran and Iraq war. But it’s not easily plausible that there is a couple of sewing needles in the cranium of a patient who has not any history of head trauma or penetrating injury. The patient was a 42-year-old man who admitted in neurology ward of Mottahari Hospital in...
traumatic brain injury is a common entity. however cerebral infarction in infants is a rare entity while the diagnosis of this pathology in the pediatric population is usually difficult. the mild head trauma is rarely accompanied by intracranial injury and even less, with cerebral infarction. we herein report the first case of cerebral infarction after a mild brain trauma in a 2-year-old latin-...
This scientific commentary refers to ‘A robust brain signature region approach for episodic memory performance in older adults’ by Fletcher et al. (doi:10.1093/brain/awab007).
