Earplugs and headphones are essential because children are often afraid of loud noises. With mirrors the look out of the system is possible and they can see their parents. Talk often with the child. If the children are tired and not hungry it is the best time for an examination especially at very small children.
particularly childrens around 2yrs-8yrs its better to wake them up early than usual and allow them to play or take them for a ride(not to make sleep till they reach mri centre) 60% of children will coperate (with out sedation)
