In what context is intravascular ultrasound (IVUS) used?

Intravascular ultrasound (IVUS) is specifically used to visualize the interior of blood vessels during interventional procedures. This technique provides real-time imaging from within the blood vessel, allowing for detailed assessment of the vessel structure. IVUS is particularly valuable during interventions such as angioplasty and stent placement, where understanding the anatomy and pathology of the vessel is critical for successful outcomes.

Using IVUS aids in evaluating the extent of arterial lesions, determining the characteristics of plaques, and assessing the stent deployment, thereby enabling practitioners to make informed decisions during procedures. This capability makes IVUS an essential tool in vascular interventions rather than for routine check-ups, diagnosing arterial blockages solely, or assessing heart valve function, which are outside the primary application of this technology.
