Intravascular Imaging at Clemenceau Medical Center Hospital Dubai

Intravascular imaging is a technique used to visualize the inside of the blood vessels, including the coronary arteries, from within. Cardiologists trained in the use of this type of imaging can provide more important information for the diagnosis and management of cardiovascular diseases, such as coronary artery disease (CAD), that can help guide the placement of stents and other therapeutic devices.

At CMC Hospital, our Interventional Cardiologists in Dubai our subject matter experts in these additional techniques that ensure you are provided the most information possible to treat your condition.

There are two main types of intravascular imaging:

  • Intravascular Ultrasound (IVUS)
  • Optical Coherence Tomography (OCT)

Intravascular Ultrasound (IVUS)

IVUS uses high-frequency sound waves to create images of the inside of the blood vessels. The sound waves are transmitted into the blood vessel and bounce back to the IVUS catheter, which is equipped with a transducer. The reflected sound waves are then processed by a computer to create a cross-sectional image of the blood vessel wall.

IVUS has several advantages. One of the main advantages is its high resolution, which allows for a detailed visualization of the blood vessel wall, including the thickness of the vessel wall and the size of any plaques or stenoses (narrowings) present. Additionally, IVUS is relatively low risk and does not expose patients to ionizing radiation, making it a safe and convenient alternative to other imaging modalities.

Optical Coherence Tomography (OCT)

OCT is a newer intravascular imaging modality that uses light waves to create images of the inside of the blood vessels. The light waves are transmitted into the blood vessel and bounce back to the OCT catheter, which is equipped with a light sensor. The reflected light waves are then processed by a computer to create a high-resolution cross-sectional image of the blood vessel wall.

Advantages & Limitations of OCT vs IVUS

OCT has several advantages over IVUS. It has higher resolution, which allows for a more detailed visualization of the blood vessel wall, including the presence of any plaques or narrowing’s. Additionally, OCT images can be acquired much more quickly than IVUS images, allowing for real-time visualization of the blood vessel wall during procedures such as PCI. However, OCT has some limitations compared to IVUS. Images generated by OCT may be subject to artifacts due to motion or other factors.

Ultimately, the choice between IVUS and OCT will depend on the specific clinical situation and the preferences of the physician, and both modalities have important roles to play in the management of cardiovascular diseases.
