A new artificial intelligence (AI) solution assesses cerebrovascular status by quantifying computerized tomography (CT) perfusion scans.

The icometrix (Leuven, Belgium) icobrain cva is a cloud-based solution designed to provide fully-automated software reports on lesion core volume and perfusion by quantifying Tmax abnormality and cerebral blood flow (CBF) abnormality, and correlation with the mismatch in volume and ratio; providing an arterial input function/venous output function (AIF/VOF) graph; and providing insights into the perfusion state of the tissue through perfusion maps.

The analysis provides color-coded segmentation, and also includes information on the correctness of the selected arterial input function and the quality of the output. Both the report and the perfusion maps can be delivered directly to the picture archiving and communication systems (PACS) and to and e-mail inbox. The automated assessment of tissue parameters in an acute clinical setting can improve patient outcomes and care by ensuring they get the right treatment (thrombectomy, blood thinners, etc.) in a timely manner.

“With the launch of icobrain cva we address a persisting need in the treatment of acute ischemic stroke,” said Wim Van Hecke, CEO of icometrix. “By democratizing advanced CT perfusion analysis for healthcare systems worldwide, we take the next step in our mission to become a holistic brain solution provider.”

Rapid and effective revascularization is the mainstay of acute ischemic stroke treatment. Until recently, intravenous recombinant tissue-type plasminogen activator (r-tPA) was the only established therapeutic option. New studies have proven the benefit of endovascular treatment, and thrombectomy with stent retrievers is now recommended as the standard of care for acute ischemic strokes with a proximal large vessel occlusion in the anterior circulation.
