WebOct 1, 2024 · CTA is minimally invasive and costs less time than MRA . Many studies demonstrated the efficacy of CTA in diagnosing ICAS and acute LVO-related AIS, and its sensitivity was promising in referencing the DSA [42,43,44]. However, the efficacy of CTA in distinguishing ICAS-LVO-related AIS from other etiologies of stroke is unknown. WebCMS approved an NTAP for radiological computer-assisted triage and notification software that analyzes CTA images of the brain and notifies hospital staff when a suspected large vessel occlusion (LVO) is identified. As a product utilizing this approved technology, Rapid LVO explicitly meets NTAP requirements and is covered by the FY2024 IPPS Rule.
