  1. In stroke care, what does LVO stand for?
    • Low ventricular output
    • Lateral vision obstruction
    • Large vessel occlusion
    • Localized vascular overflow
  2. How do computer-aided triage and notification (CADt) tools fit into the stroke workflow?
    • They run in parallel with the radiologist's read and alert the stroke team to suspected cases
    • They replace the radiologist's diagnostic read
    • They perform the thrombectomy procedure
    • They only analyze scans after treatment is complete
  3. What was notable about CMS's 2020 decision on Viz.ai's software?
    • It banned AI stroke tools
    • It required every hospital to buy the software
    • It classified the software as a drug
    • It granted a new technology add-on payment, the first for an AI tool
  4. What did the DAWN and DEFUSE 3 trials show?
    • AI can replace neurologists
    • Some patients benefit from thrombectomy up to 24 hours after onset when imaging shows salvageable tissue
    • Thrombectomy is never useful after 6 hours
    • CT scans are unnecessary for stroke
  5. If a CADt tool misses a stroke on a scan, what does that mean?
    • The patient definitely does not have a stroke
    • The scan is deleted
    • The patient is discharged automatically
    • The case follows the normal reading workflow; stroke has not been ruled out
  6. Which occlusions are generally harder for LVO detection models to find?
    • Distal branch occlusions
    • Internal carotid artery occlusions
    • M1 segment occlusions of the middle cerebral artery
    • All occlusions are equally easy
  7. What can distort the core and penumbra volumes estimated by perfusion software?
    • Using a mobile viewer
    • The time of day the scan is taken
    • Patient motion or poor contrast bolus timing
    • Sending alerts to the stroke team
  8. How do algorithms help in epilepsy care, according to the guide?
    • By performing brain surgery
    • By helping review long EEG recordings and flagging suspected seizures
    • By prescribing anti-seizure medication automatically
    • By replacing MRI scans
