By definition an angiogram is vessel perfusion testing with contrast medium. CAT scan angiogram (CTA). CTA tests use computerized x-ray scanning and are a less invasive way to look at the heart, heart arteries and aortas. Both MRI and CTA tests form three-dimensional imaging of the areas under examination.
State-of -art CT scan, 258 slice is in 3D and when slices are reassembled the image is very close to be live viewing and that includes blood flow (4D).
Thanks for your question,
