title: Non-invasive imaging of intracranial pediatric vascular lesions.
abstract: OBJECTIVE
  The goal of this review is to discuss the different non-invasive imaging techniques as well as the age-specific pediatric vascular pathologies and their imaging features.
  
  
  METHODS
  Ultrasound, computed tomography, and magnetic resonance imaging features of pediatric ischemic stroke, intracranial hemorrhage, aneurysms, cavernomas, developmental venous anomalies, and arteriovenous malformations are presented. In addition, multiple non-invasive angiographic techniques (CT and MR angiography) and functional MRI sequences (diffusion, perfusion, and susceptibility-weighted imaging) are discussed.
  
  
  CONCLUSIONS
  Neurovascular imaging plays a central role in the early, sensitive, and specific diagnosis of pediatric intracranial vascular disorders. A detailed knowledge of the quality and exact angioarchitecture of pediatric vascular pathologies as well as their impact on the cerebral hemo-dynamics is essential to guide and monitor treatment options and to predict functional outcome.
