7 Angiogram Silhouette Cross-section
Additionally, angiography by itself causes ambiguity. These are illustrations of the same lesion as viewed at different angles.. As you can see, in one view the lesion is 75%, in the other 26%. How many times have you seen a physician call for one more picture? This continues for several angles and they still don’t have the answer. This continues until their partner is called for advice and there is still a difference of opinion. This all could have been avoided had IVUS been performed as soon as there was a question surrounding that particular lesion. This in itself is a savings of time and patient exposure to further, unnecessary contrast injections.

8 Clinical use of IVUS Assesses severity of disease
Measures diameters for stent choice Assesses completeness of treatment Accuracy of placement
