How does the concept of “model as a dataset” reshape traditional data-sharing practices in medical imaging?
|
It enables sharing of learned model weights instead of sensitive raw images. |
|
Because the model learns from medical images, so people can share the model instead of sharing real patient images |

Which analytical conclusion can be drawn about the trade-offs between physics-informed and statistical models?
|
Physics-informed models are more interpretable but computationally intensive. |
|
Because Physics-informed models used biological and physics rules, so they are easier to understand. However, they often require more computing power |

Why is “mode collapse” considered a critical problem in GAN-based medical image synthesis?
|
|
|
Because mode collapses appears when a GAN keeps generate similar images instead of other varie image. This reduce the diversity and quality of the generated images |

Why are healthcare-specific metrics preferred over general-purpose metrics such as FID or SSIM?
|
They better capture clinical accuracy and diagnostic relevance. |
|
healthcare-specific metric are better because they check if the medical image is correct and useful for doctors, not just if it looks good |

What does the article identify as the key tension between privacy preservation and image fidelity?
|
Higher realism may risk reproducing identifiable patient data. |
|
Because If AI makes images look very real, it is may copy parts of real patient images. This can put patient privacy at risk |

Why is the FDA’s approval of synthetic MRI technology significant for future AI-generated data?
|
It establishes a framework for validating synthetic data equivalence in clinical use. |
|
Because the FDA approval shows that synthetic images can be use if they works as well as real images. This guide for testing and approving future AI-generated medical data |

Which strategy would best mitigate demographic bias in generative models according to the article?
|
Ignoring population-level variation |
|
Because different group of people can have different health risks. Ignore these differences can make the AI less accurate |

How do DDPMs exemplify versatility in healthcare image synthesis?
|
They can perform multiple tasks such as denoising, inpainting, and anomaly detection without retraining. |
|
Because DDPMs can do many different jobs, such as removing noises, without needing to be trained again |

Why is regional calibration essential when applying risk prediction models across countries?
|
To adjust for population-specific incidence and lifestyle differences |
|
Because different countries have different disease rates and risk factors. Risk modols need to be adjust so they can give accurating results for each population |

What analytical conclusion can be drawn when comparing the China-PAR and Framingham models?
|

|
Because China-PAR was develope by using data from Chinese population, so it can predicting cardiovascular risks in Chinese people more accurate than the Framingham model |

Based on CVD mortality data, what analytical inference can be made about Japan’s position compared to neighboring countries?
|
Japan’s low CVD mortality suggests effective prevention and healthcare systems. |
|
Japan has lower CVD death rates than many nearby countries. This show how the healthcare system and disease prevention work |

According to the “image generation trilemma” shown in the figure, what analytical conclusion can be drawn about the relative strengths of VAEs, GANs, and DDPMs in medical image synthesis?
|
GANs provide a balance between image quality and diversity but may suffer from mode collapse. |
|
Because GANs can create realistic and diversity images, but sometimes they keep generate similar image |

Based on Figure, what analytical conclusion can be drawn regarding the distribution of cardiovascular disease (CVD) subtypes across East Asian countries?
|
Ischemic heart disease (IHD) accounts for a higher proportion of CVD deaths in Japan and South Korea compared with China, suggesting regional lifestyle or prevention differences. |
|
Japan and South Korea have more deaths from heart disease, when China has more death from stroke. This shows that CVD patterns is different in each country |
