SWOT analyses of current stroke and neurovascular imaging.

	Favorable	Unfavorable
Internal	Strengths - noninvasive imaging of cerebral vessels and perfusion providing insight into stroke pathophysiology - standardized imaging protocols - improved technology: rapid, becoming more simple to use - HIPAA-secure cloud technology	Weaknesses - perceived complexity of imaging - potential delay caused by imaging - cost of imaging
External	Opportunities - need for biomarkers - imaging may inform medical decision making for stroke prevention, treatment selection and monitoring, rehabilitation tools already exist for widespread image acqusition, transmission and processing - StrokeNet initiative - stroke imaging CDEs - clinical practice often includes serial imaging - imaging may reduce costs through allowing smaller sample sizes - imaging may inform adaptive trial design	Threats - contradictory results of image-guide acute stroke trials, with no central or standardized data collection and no pooled analysis - no dedicated imaging RFA and no significant, dedicated funding for imaging infrastructure in StrokeNet - no plans/funding for permanent repository of images beyong trials in StrokeNet - large computing or memory needs
