Abstract

Background

Some institutions have implemented rapid MRI protocols for acute musculoskeletal (MSK) infections as an attempt to improve early diagnosis.

Objective

To assess current utilization of pediatric rapid MSK MRI protocols (abbreviated protocol, no IV (intravenous) contrast, and no sedation) using a survey.

Materials and methods

A 10-question survey was sent to members of the Society for Pediatric Radiology (SPR) and the Society of Skeletal Radiology, which differed depending on whether a rapid protocol was used or not. The survey was conducted by the SPR MSK and MRI committees.

Results

A total of 134 surveys (representing 99 institutions) were completed. Twenty-two percent (22/99) of institutions used a rapid protocol. Pediatric institutions were more likely to perform it when compared to adult institutions (P-value<0.01, 37% (14/38) vs. 13% (8/61)). Comparing institutions that use rapid protocol with institutions that do not, the availability of on-call MRI technologists did not differ (P-value=0.33), and pediatric radiologists were more likely to interpret these studies (73% (16/22) vs. 36% (28/77), P-value=0.02). Reported rapid MRI completion times took less than 15 min in 64% (14/22) of the institutions. Seventy-three percent (16/22) of institutions performing rapid protocols have radiologists check images to evaluate the need for additional sequences or contrast. Sixty-eight percent (25/37) reported being very satisfied with rapid protocols. Seventy-seven of 99 institutions do not use a rapid protocol due to a lack of a consensus protocol and concerns about missing findings. Of these institutions, 62% (48/77) administer IV contrast routinely.

Conclusion

There is limited and variable utilization of rapid MRI protocols for acute pediatric MSK infection. Lack of accepted consensus protocol is the most common reason for non-implementation, highlighting the need for consensus-driven rapid protocols.
