Stroke imaging technology could reduce brain damage risk

A study presented at the Society of NeuroInterventional Surgery's (SNIS) 15th Annual Meeting has found that a new stroke imaging technology called cone beam imaging could decrease delays in patient care by up to an hour, giving patients a better chance of making a full recovery.

A study presented at the Society of NeuroInterventional Surgery’s (SNIS) 15th Annual Meeting has found that a new stroke imaging technology called cone beam imaging could decrease delays in patient care by up to an hour, giving patients a better chance of making a full recovery.

The study is called New Multiple CT Assessment of Acute Stroke Patients: Are We Ready for Prime Time?, and has shown that recent advances in imaging software in the angiosuite can give neurointerventionalists the details required to diagnose patients with large vessel occlusion (LVO) for an endovascular thrombectomy (EVT). The research also suggested that, in the future, stroke patients could bypass a CT scan or an emergency department and go straight to the angiosuite for imaging and the appropriate care.

Cone beam imaging allows for the accurate detection of haemorrhage, occlusion site, ischemic core, and at-risk tissue. The study researchers want baseline imaging to be performed in the angiosuite using cone beam imaging. This type of imaging reportedly provides complete 3D views of critical anatomical areas and higher resolution images than other methods.

Toronto Western Hospital interventional clinical research technologist and lead author of the study Nicole Cancelliere said: “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.”

Transferring a patient from a CT scan to an operating room can delay EVT for up to an hour.

The preliminary results of the investigation show that cone beam imaging software compares favourably with baseline and follow-up CT scans.
