Hey mark.

There was an interesting discussion in radiology rounds on patients with mediastinal mass and the risk for SVC compression while lying supine in CT (which is potentially fatal because they collapse in CT and if you bag them you'll make things worse by increasing intrathoracic pressure even further).

That gave me an idea of predicting that potential risk in ED, prior to sending them to CT, by using ultrasound and doppler of the SVC while prone or supine. If a significant change in flow is demonstrated then extra precautions will have to be taken with these patients while doing the CT.

I thought you may be interested in it, and I think it may be something for a potential future research project.

Happy to hear your thoughts.
