What is Accuracy of smartphone-based evaluation of Emergent Large Vessel Occlusion on CTA about?
## Objectives: Mechanical thrombectomy is the standard of care for stroke caused by an emergent large vessel occlusion in the anterior circulation, and the ability to rapidly review cta is one hurdle in minimizing the time from diagnosis to intervention. we evaluated the diagnostic accuracy and confidence in review of stroke cta for elvo via a smartphone-based application as compared to pacs workstation. ## Patients and methods: Seventy-six head and neck cta studies performed for stroke from one comprehensive and seven primary stroke centers were independently reviewed remotely on smartphone by two blinded interventional neuroradiologists in actual-use circumstances. the presence and location of large vessel occlusion(s), diagnostic quality, and confidence in interpretation were recorded. comparison was made to blinded pacs workstation review performed at a delayed interval. weighted kappa and kendall's tau statistics were calculated to evaluate intra- and inter-observer reliability. ## Results: Of the 76 studies, 20 (26%) had a large vessel occlusion. 14 m1 segment occlusions (18%); 2 ica terminus (3%); 2 tandem carotid and m1 (3%); and 2 basilar artery (3%). there was 100% diagno
