  4. What regulatory pathway did FDA use for the named Viz.ai imaging device?
    • A blanket approval covering all imaging-AI tools
    • A drug marketing authorization
    • An exemption from all clinical evidence requirements
    • A De Novo classification decision for a specific device and intended use
  5. Idi pataki kan AI aworan le kuna lori data ile-iwosan tuntun ni:
    • Awọn iyatọ ninu iru scanner, Ilana, tabi olugbe alaisan lati data ikẹkọ
    • Awọn sikanu ni o wa ju lo ri

    • Awọn aworan jẹ aami nigbagbogbo nibi gbogbo
  6. What do U-Net skip connections carry from the encoder to the decoder?
    • A patient’s medical record number
    • Higher-resolution feature maps that help recover spatial detail
    • A radiology report’s billing code
    • Only a global class label
  7. Why should medical-imaging datasets generally be split at the patient level?
    • To make every scanner appear in only one dataset
    • To guarantee equal disease prevalence
    • To reduce leakage from multiple correlated images of the same patient across train and test sets
    • To remove the need for external validation
  8. What does probability calibration assess in an imaging model?
    • Whether the scanner has been recently serviced
    • Whether every image has the same resolution
    • Whether the model segments the correct number of organs
    • Whether predictions assigned a probability match observed frequencies over evaluated cases
