Mock MRI simulation for pediatric MRI.....

The ‘mock MRI’ procedure involves children undergoing a simulated scan with the assistance of a play therapist prior to the actual diagnostic scan. It acts as both a screening tool, to assist in identifying children who are likely to be able to comply with the MRI procedure,and also helps to prepare these children,by familiarizing them with the environment, sounds, and equipment, while teaching them skills (such as breathing,relaxation, or distraction) to cope with the actual procedure . Use of the ‘mock’ magnet has led to a marked reduction in the numbers of patients who have required anesthetic and reduced the time required for the diagnostic scan...... 

Pediatric MRI..............

Longer TR and TE times are generally required when imaging very young children.the high water content in neonatal brains, coupled with the lack of fatty myelin results in the reduction in CNR (contrast to noise ratio) and grey/white matter differentiation.restore pulses on T2W imaging can improve CSF contrast and allow shorter TR times to reduce scan time......
