  1. What operation lets a convolutional neural network detect local image patterns in radiology images?
    • It applies Bayes theorem to patient records
    • Convolutions apply learned filters across neighboring pixels or patches
    • It converts images into a text transcript
    • It uses a spreadsheet formula
  2. What is a possible worklist use of a radiology AI model?
    • Replace the radiologist’s final interpretation
    • Guarantee that no urgent case is missed
    • Flag a study for earlier review when a defined finding is suspected
    • Make a diagnosis for every patient without review
  3. A que se refere 'mudança de domínio' na IA radiológica?
    • Mudança no estacionamento do hospital
    • Mudando de ressonância magnética para ultrassom por diversão
    • Um tipo de formato de imagem
    • A difference between training and deployment data that can change model performance
  4. Qual arquitetura é comumente usada para delinear (segmentar) um tumor pixel por pixel?
    • Rede U
    • SORRISOS
    • XGBoost
    • JPEG
  5. What was the ScreenTrustCAD study design for screening mammograms?
    • A retrospective study of chest CT only
    • A prospective paired-reader study comparing interpretations from two radiologists and AI CAD
    • A study comparing image file sizes across scanners
    • A trial of autonomous treatment planning
  6. Quais métricas são comumente usadas para avaliar um modelo de IA radiológica?
    • Potência e torque
    • Contagem de palavras e tamanho da fonte
    • Sensibilidade, especificidade e AUC
    • Vida útil da bateria
  7. What does FDA authorization of an AI radiology device establish?
    • That it is accurate for every possible clinical use
    • That it replaces a radiologist’s judgment
    • That it needs no monitoring after deployment
    • That the device met applicable premarket requirements for its intended use
  8. How many women were included in the 2025 ScreenTrustCAD human-AI interaction analysis?
