Assessing Radiology Practice Patterns for Obtaining MRI in Pediatric Patients with MR-Conditional Tracheostomy Tubes.
Objectives: Silicone tracheostomy tubes are a popular choice for pediatric patients with chronic tracheostomies due to their pliability and increased comfort. However, the presence of wire reinforcement causes them to be labeled "MR-conditional." The objective of this study was to understand practice patterns across radiology departments for obtaining MRI in children with MR-conditional tracheostomy tubes.
Methods: A survey consisting of 7 questions aimed at determining a facility's protocol for obtaining MRI in children with tracheostomy tubes was developed and administered via telephone to MRI technologists at US children's hospitals.
Results: 182 children's hospitals were identified and 59 responses were obtained across 30 states (32.4%). 19 sites (32%) were excluded as they were unable to perform MRI. All 40 facilities reported that they have a standard questionnaire for medical implants, however only 20 reported that tracheostomy tubes are included on that questionnaire (50%). 6 (15%) reported all MR-conditional tubes are changed to MR-safe ones. Of the remaining 34, protocols were as follows: 1 (2.9%) scans patients with conditional tubes for a maximum of 15 minutes, 5 (14.7%) only use a 1.5T magnet, and 28 (82.3%) reported following the manufacturer conditions. In terms of artifact, 3 sites change MR-conditional tubes to MR-safe if scanning the head, neck, chest, or abdomen (8.8%), 6 (17.6%) change the tube if scanning the head or neck, 15 (44.1%) change the tube only if scanning the neck, and 10 (29.4%) were not aware of issues with artifact.
Conclusion: Based on this survey of MRI technologists at US children's hospitals, there is no unified protocol for obtaining MRI in pediatric patients with MR-conditional tracheostomy tubes. A lack of standardized protocols may be contributing to unnecessary tracheostomy changes. Future research includes clearly defining the anatomical regions affected by wire-related artifact and developing a standardized MRI protocol for these patients.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
