Intravascular Ultrasound Imaging Technique

Intravascular Ultrasound

Intravascular ultrasound (IVUS) is a catheter-based imaging technique pivotal in diagnosing and treating cardiovascular diseases. Unlike traditional methods that visualise the exterior of blood vessels, IVUS allows clinicians to view a cross-sectional image of the inside of the arteries. This perspective is invaluable for assessing the severity and characteristics of atherosclerotic plaques, which can lead to heart attacks and strokes if left unchecked.

IVUS is particularly beneficial in interventional cardiology. During procedures such as angioplasty or stent placement, IVUS provides real-time, detailed images of the blood vessel walls. This information assists doctors in making precise modifications to the vessels, ensuring optimal placement and expansion of stents. The ability to measure the size and composition of plaque with IVUS also helps in deciding the most appropriate therapeutic approach, potentially leading to better patient outcomes.

Moreover, IVUS plays a crucial role in evaluating the success of treatments. Post-procedure, it can confirm the adequate expansion of a stent and the absence of complications such as dissections or residual stenosis. This verification is critical to ensure the intervention’s long-term success and minimise the risk of future cardiac events.

In addition to its clinical applications, IVUS aids in advancing research on vascular diseases. By providing a deeper understanding of disease mechanisms and the effects of various treatments, IVUS contributes significantly to the development of more effective therapies.

Overall, intravascular ultrasound is an essential tool in the arsenal of modern medicine, enhancing diagnostic capabilities, refining therapeutic interventions, and improving patient care in cardiology.
