Imaging the microstructure of the arterial wall - ex vivo to in vivo potential.

Summary: Imagine being able to look closely at the tiny building blocks of our blood vessels. This paper reviews new tools that let scientists do just that! By taking detailed pictures of artery walls, researchers can learn how blood vessels work, spot diseases earlier, and even build new, healthy arteries in the lab. These safe, non-invasive cameras are changing the way we understand heart health and could lead to better tests for patients in the future.
