What is one major ethical concern associated with generative AI in medical imaging?

A major ethical concern is data copying and patient reidentification. Because AI may create images that look very close to real patient images. This can make patient privacy at risk because someone can be able to identify the patient from the image

From the article Exploring the potential of generative artificial intelligence in medical image synthesis: opportunities, challenges, and future directions. In Patient privacy and data copying, it stated that generative model is trained on a specific dataset and can replicate images that closely resemble the original data, the model might inadvertently reveal sensitive patient information.

Why might Western-based risk prediction models overestimate ASCVD risk in East Asian populations?

Because Western ASCVD risk prediction models was developed using data from White populations in the United States. But East Asian populations often have different disease and a lower baseline risk of some ASCVD outcomes

From Atherosclerotic Cardiovascular Disease Risk Prediction Models in China, Japan, and Korea: Implications for East Asians. In abstract, it stated that The management of atherosclerotic cardiovascular disease (ASCVD) in the United States is currently based upon large epidemiological studies in primarily non-Hispanic White subjects.
