Reply #12: The latest technology IVUS is more accurate than the angiogram.

[reprobate]

Intra Venous Ultra Sound sends a miniature ultrasound probe into the arteries like the angiogram does with the wire lead, and it then does an ultrasound picture of the artery, including the inner and outer walls, and the lumen, the actual opening in the artery. It also shows the size and placement of the blockage.

One thing that's open to inaccuracies in the angiogram is that the artery will grow in width as the clog increases.
