Odpowiedzi i wyjaśnienia pojawiają się w miarę rozwiązywania quizu.

1. How is the adenoma detection rate defined?
   • The share of screening colonoscopies in which at least one adenoma is found
   • The number of polyps removed per hour
   • The percentage of polyps that are cancerous
   • The time taken to withdraw the scope
2. What did the 2014 New England Journal of Medicine study link higher endoscopist ADR to?
   • Longer procedure times
   • More patient complaints
   • Lower risk of cancers appearing between screenings
   • Higher rates of bowel perforation
3. Which device became the first CADe system authorized by the FDA, in 2021?
   • Fujifilm CAD EYE
   • Medtronic GI Genius
   • Olympus ENDO-AID
   • Wision EndoScreener
4. Which kind of polyps account for most of the extra detections from CADe in trials?
   • Large advanced cancers
   • Polyps outside the colon
   • Only inflamed tissue
   • Small and diminutive adenomas under about 5 mm
5. Why do CADe systems require a detection to persist across several frames before alerting?
   • To reduce flicker and false alarms from bubbles, reflections and folds
   • To save battery power
   • To wait for the pathologist
   • To record the video
6. What did the 2025 observational study from Poland suggest?
   • CADe doubled detection of advanced cancers
   • Endoscopists' ADR on non-AI procedures fell after routine AI use
   • CADe had no false alarms
   • Patients preferred procedures without AI
7. What is the difference between CADe and CADx?
   • CADe is for the stomach, CADx for the colon
   • CADx is used only after surgery
   • CADe locates polyps, while CADx classifies what type a polyp likely is
   • They are two names for the same system
8. Why can't CADe make up for poor bowel preparation or rushed withdrawal?
   • It only works on the stomach
   • It turns off when stool is present
   • It needs a pathologist present
   • It can only analyze mucosa the camera actually shows
