Pediatric neuroradiology: a perspective.

چکیده
~n the evaluation of a developing organ system, it ts a challenge to recognize the continuously changing state of normal, identify variations of normal, appreciate abnormalities, and assess their significance. So it is in pediatric neuroradiology (1~, exemplified by the trite, often overused aphonsm-a child is not simply a small adult. The very complexity of the developing central nervous system (CNS) demands a practical approach to learning its developmental stages and variations of morphologic arrests and acquired insults, the derangements that ultimately, and evolve the associated clinical manifestations. Modern imaging techniques demonstrate in exquisite detail the CNS anatomy and any abnormality present. We have come a long way since pediatric neuroradiology began as a persuasion 24 years ago (Figs. 1 and 2). We now show the pathology well. The clinical challenge is to do so safely, in often tiny people with fragile physiologies. We must modify, to pediatric specifications, equipment design and construction, catheters, probes, needles, contrast agents, support systems, sedation and anaesthesia, MR coils, imaging doses, and pulse parameters, lest we place the children at increased risk to achieve reduced diagnostic benefit. The developing CNS has unique features that modify its reaction to common insults. Because it is developing, insults to the CNS may cause morphologic deviations from the planned blue-

Arterial ischemic stroke (AIS) in adults is considered a serious health threat and requires urgent medical treatment. Prompt diagnosis allows the therapeutic option of thrombolysis within the time window of 3 to 6 hours after first symptoms. Alternatively, early anti-platelet therapy is effective in improving the outcome after stroke. The incidence of pediatric AIS range from 2 to 5 per 100 000...
