Novel stroke imaging cuts transfer delays 1 hour, may reduce brain damage

A new stroke imaging technology presented Tuesday, July 24, at the Society of NeuroInterventional Surgery’s 15th annual meeting could reduce delays in care by an hour, providing patients a better shot at full recovery, according to a release.

The use of cone beam imaging software was part of a recent study. In it, authors demonstrate how advances in imaging software in the angiosuite provide neurointerventionalists with the information to diagnose large vessel occlusion (LVO) for an endovascular thrombectomy (EVT).

The study, published in the Journal of NeuroInterventional Surgery found, in the future, those with stroke may skip the CT scan or emergency department and head to the angiosuite to receive care—potentially saving 60 minutes in delays.

"By using this technology in the angiosuite, hospitals can reduce intra-facility transfer delays and hence the time of stroke symptom onset to treatment, which will significantly reduce brain damage and improve outcomes for patients," said Nicole Cancelliere, lead author of the study and an interventional clinical research technologist at Toronto Western Hospital in the statement.

Initial results of the study determined cone beam imaging software was on-par with baseline and follow-up CT. Additionally, the software could accurately detect hemorrhage, occlusion site, ischemic core and tissue at risk, according to the release. Thus, authors reported baseline imaging could be performed in the angiosuite using cone beam imaging.
