Final answer:
To evaluate for graft or stent abnormalities while scanning, look for signs of blockages, leakage/dislodgement, and infection/inflammation.
Step-by-step explanation:
When evaluating for graft or stent abnormalities while scanning, there are several things to look for. Firstly, check for any signs of blockages or narrowing in the vessels, which might indicate a graft or stent that is not functioning properly. Next, look for signs of leakage or dislodgement of the graft or stent. This can be indicated by abnormal flow patterns or pooling of blood. Finally, assess the surrounding tissues for any signs of infection or inflammation, which could suggest a problem with the graft or stent.
