DeepSymNet: AI Methods for Stroke Imaging

Description:

Determining if a patient can benefit from acute stroke treatments (endovascular thrombectomy and late window thrombolysis) relies on the use of advanced imaging modalities such as CT Perfusion (CTP) or MRI, which are not available at the majority of community hospitals and primary stroke centers.  Transferring all patients who could potentially need treatment to advanced-imaging capable centers is cost-prohibitive and impractical.

 

Investigators at UTHealth have addressed this problem by developing unique AI-machine learning methodologies to generate the types of information produced by CTP from a widely available imaging modality: CT angiogram.  This novel approach allows for screening of a vastly expanded population of patients for life-saving acute stroke treatments.

 

Key Benefits

-Ability to detect large vessel occlusion and predict ischemic core and penumbral volumes from CT angiogram with comparable accuracy to CTP studies.

-Potential to improve patient access to endovascular therapy

-Large dataset from Memorial Hermann (MH) Hospital System in Houston

-Live framework of immediate data transfer and analysis at multiple MH campuses

-Validated on multiple scanners, multiple hospitals, multiple cities

-Developed by interdisciplinary team combining stroke and machine learning expertise

-“One-stop-shop” with clinical and technical expertise for technology development and validation with multicenter data

 

Stage of Development

The DeepSymNet tool has been validated in restrospective studies and is actively being tested prospectively at multiple Memorial Hermann Hospitals to optimize the clinical workflow.
