ABSTRACT
BACKGROUND:
Young children requiring clinical magnetic resonance imaging (MRI) may be given general anesthesia. General anesthesia has potential side effects, is costly, and introduces logistical challenges. Thus, methods that allow children to undergo awake MRI scans are desirable.OBJECTIVES:
To compare the effectiveness of mock scanner training with a child life specialist, play-based training with a child life specialist, and home book and video preparation by parents to allow non-sedated clinical MRI scanning in children aged 3-7 years. MATERIALS ANDMETHODS:
Children (3-7 years, n=122) undergoing clinical MRI scans at the Alberta Children's Hospital were invited to participate and randomized to one of three groups home-based preparation materials, training with a child life specialist (no mock MRI), or training in a mock MRI with a child life specialist. Training occurred a few days prior to their MRI. Self- and parent-reported functioning (PedsQL VAS) were assessed pre/post-training (for the two training groups) and pre/post-MRI. Scan success was determined by a pediatric radiologist.RESULTS:
Overall, 91% (111/122) of children successfully completed an awake MRI. There were no significant differences between the mock scanner (89%, 32/36), child life (88%, 34/39), and at-home (96%, 45/47) groups (P=0.34). Total functioning scores were similar across groups; however, the mock scanner group had significantly lower self-reported fear (F=3.2, P=0.04), parent-reported sadness (F=3.3, P=0.04), and worry (F=3.5, P=0.03) prior to MRI. Children with unsuccessful scans were younger (4.5 vs. 5.7 years, P<0.001).CONCLUSIONS:
Most young children can tolerate awake MRI scans and do not need to be routinely anesthetized. All preparation methods tested, including at-home materials, were effective.Palavras-chave
