A member asked:
Will a ct scan or mri show coronary arteries without the dye?

Yes sort of: The problem is that MRI using blow flow contrast and not dye only shows the main portion of the coronary arteries but not the smaller branches. If you use ct is uses contrast and lots of radiation. Neither can replace a contrast angiogram.

Not well: A contrast enhanced exam is necessary to assess the coronary arteries in a meaningful way in young patients. Cardiologists use contrast for catheterization, but noninvasive coronary angiography with contrast is preferable.
