Recognition, context, and distinction

01

What am I looking at?

Visual recognition

Fine intravascular imaging catheter connected to a dedicated imaging console; the distal segment houses the ultrasound transducer rather than a conventional open diagnostic tip.

02

What does it do, and where will I see it?

Use & procedural context

Catheter with a miniature ultrasound transducer at its tip that images the vessel from within, sizing lumen and wall and confirming stent apposition where contrast angiography falls short. Typical procedural contexts include venous stenting (iliocaval, May-Thurner), IVC filter and EVAR sizing, and characterizing ambiguous lesions.

03

What most clearly distinguishes it from similar devices?

Key distinctions

IVUS is an imaging catheter rather than a conventional injection or selection catheter; the distal transducer provides intraluminal imaging instead of relying solely on contrast opacification.
