What does IVUS refer to in medical diagnostics?

Intravascular ultrasound (IVUS) is a valuable diagnostic imaging technique commonly used in the field of cardiology and vascular medicine. It involves the use of a catheter equipped with an ultrasound device that is inserted into blood vessels, allowing for detailed imaging from within the vessel itself. This method provides real-time, cross-sectional images of the vascular structure, enabling healthcare providers to assess the condition of the arteries, including the presence of atherosclerosis, plaque formation, and other abnormalities.

The use of intravascular ultrasound is crucial for guiding interventional procedures, evaluating stents, and planning treatments for cardiovascular diseases. By providing a perspective that standard ultrasound techniques cannot, IVUS offers enhanced visualization that significantly aids in patient diagnosis and management. This particular utility and focus on internal vascular assessment distinguish IVUS from the other incorrect options, which do not accurately represent this specialized imaging modality.
