CT Coronary Angiogram

Advanced Imaging Techniques for Coronary Arteries

A Computerized Tomography (CT) Coronary Angiogram is a non-invasive imaging test used to examine the arteries supplying blood to the heart. This test utilizes a high-resolution X-ray machine to generate detailed images of the heart and its blood vessels. It helps diagnose various heart conditions, detect narrowed or blocked arteries, and guide further treatment plans.

Intravascular Imaging Techniques

Intravascular Ultrasound (IVUS)

IVUS is a minimally invasive imaging technique that uses an ultrasound transducer mounted on a catheter to provide real-time images of blood vessels from inside the artery.

✅ Applications of IVUS:

Measures vessel and lumen diameter
Determines lesion length and plaque buildup
Assesses plaque composition
Ensures proper stent placement and deployment
Evaluates the effectiveness of balloon angioplasty or stenting during follow-ups

Optical Coherence Tomography (OCT)

OCT is an emerging high-resolution imaging technology that provides micron-level cross-sectional images of tissue structure. Unlike ultrasound, OCT uses light instead of sound to create images.

✅ Advantages of OCT in Cardiology:

Enables high-resolution imaging of blood vessels
Provides real-time, in situ optical biopsy without tissue removal
Helps detect microvascular disease and stent malapposition
Reduces sampling errors in tissue diagnosis
Assists in guiding interventional procedures

These advanced imaging technologies—CT Coronary Angiogram, IVUS, and OCT—play a crucial role in diagnosing coronary artery disease (CAD) and optimizing treatment strategies, ensuring better outcomes for patients.
