BACKGROUND AND PURPOSE Arterial spin-labeling (ASL) was recently introduced as a noninvasive method to evaluate cerebral hemodynamics. The purposes of this study were to assess the ability of ASL imaging to detect crossed cerebellar diaschisis (CCD) in patients with their first unilateral supratentorial hyperacute stroke and to identify imaging or clinical factors significantly associated with ...

stroke is the third cause of death in the world after the cancer and cardiovascular disease. . it has been shown that stroke in northeast of iran occurs approximately one decade earlier than in western countries. reasons for the high stroke incidence among persian are not yet clear. it is the first gene-association study in persian population, which determines the relationship between 25 gene v...

  Background: Embolus is one of the causes of ischemic stroke that can be due to cardiac sources such as valvular heart diseases and atrial fibrillation and atheroma of the aorta. Transesophageal echocardiography (TEE) is superior in identifying potential cardiac sources of emboli. Due to insufficient data on TEE findings in ischemic stroke in Iran, the present study was done to evaluate TEE in...

OBJECTIVE To investigate whether early stage diffusion tensor tractography (DTT) values predict motor function at 3 months after onset in supratentorial stroke patients with severe motor involvement. METHODS A retrospective study design was used to analyze medical records and neuroimaging data of 49 supratentorial stroke patients with severe motor involvement. Diffusion tensor imaging was ass...

BACKGROUND AND PURPOSE Leukoaraiosis is a common finding among patients with ischemic stroke and has been associated with poor stroke outcomes. Our aim was to ascertain whether the severity of pre-existing leukoaraiosis is associated with outcome in patients with acute ischemic stroke who are treated with endovascular stroke therapy. MATERIALS AND METHODS We retrospectively analyzed data from...

Supratentorial stroke presenting as contralateral hemiparesis is predominantly related to contralateral projection of the corticospinal tract. While most corticospinal fibers decussate at the level of the medulla, some tracts continue descending as ipsilateral ventral corticospinal fibers. In this systematic review of the literature and 2 case reports specifically seen in our institute, we desc...

BACKGROUND AND PURPOSE Larger infarct volume as a percent of supratentorial brain volume (SBV) predicts poor outcome and hemorrhagic transformation in childhood arterial ischemic stroke (AIS). In perinatal AIS, higher scores on a modified pediatric version of the Alberta Stroke Program Early CT Score using acute MRI (modASPECTS) predict later seizure occurrence. The objectives were to establish...

conclusions opium was not identified as a risk factor of ischemic stroke. a more extended survey considering further confounding factors is recommended. background one of the supposed risk factors of ischemic stroke is opium addiction, while the researches about its prevalence among patients with stroke are limited. objectives the aim of this study was comparing the prevalence of opium addictio...

myxomas, the most common primary cardiac tumors, are known as a source of cardiogenic emboli. the possibility of their early detection has made them of great importance for emergency medicines. detection of the disease is probable at early stages using echocardiography and associate complications such as syncope, cerebral embolic ischemic strokes, and sudden death. we report experience of a rar...
