Hello, I was just wondering if anyone can provide clarification for if a NT triple lumen would need to have a chest xray taken within 24 hours to verify tip placement prior to using the line for a CT scan with power injection? Some of our radiologists are telling us that it is necessary but I can't find any supporting documentation. They are only saying it is what they want for NT triple lumen CVC not with our PICCs? Any help is greatly appreciated! I have always thought that if the device is deemed power injectable by the manufacturer guidelines and flushes without resistance and gets good blood return you could use it for power injection.
