Neck CT angiogram (intraosseous vascular access)
Sudden drop in GCS post self strangulation, patient has no IV access.

This case demonstrates a successful use of administering iodinated contrast via intraosseous vascular access. When contrast is administered into the medullary cavity, it enters venous circulation via intramedullary or emissary vessels.
An intraosseous cannulation is a viable option for critical patients where IV access is not readily available and a contrast scan would make an impact on patient management.
