A new MRI Try Without sedation program significantly reduces wait times for pediatric patients needing MRI scans. This approach, utilizing child life specialists, ensures diagnostic image quality while improving access to essential imaging services.
Area of Science:
- Pediatric Radiology
- Medical Imaging Techniques
- Patient Care Management
Background:
- Pediatric patients often require sedation for MRI scans to achieve diagnostic image quality.
- Long wait times for sedated MRI scans are common due to high patient volumes and limited sedation resources.
Purpose of the Study:
- To evaluate the effectiveness of an MRI Try Without sedation program.
- To determine if this program can decrease MRI wait times while maintaining diagnostic image quality.
Main Methods:
- Retrospective chart review of 134 pediatric patients from April 2014 to June 2015.
- Inclusion of child life specialist interventions and recording of access time (order to completion).
- Evaluation of MRI image quality by a pediatric neuroradiologist.
Main Results:
- The MRI Try Without program averaged 15.4 days from order to completion.
- This contrasts with an average of 46.2 days for the third available sedation/anesthesia appointment.
- 87.3% of scans achieved "good" or "very good" image quality, with only 3.8% requiring re-examination.
Conclusions:
- An MRI Try Without sedation program, incorporating child life specialist interventions, effectively reduces MRI wait times for pediatric patients.
- Diagnostic-quality MRI images can be achieved without sedation in a significant majority of pediatric cases.
- This program improves access to MRI services for children by optimizing resource utilization.

MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
