Intravascular Ultrasound IVUS
4
Feb

Overview

IVUS provides cross sectional images of vessel lumen and wall from within the artery guiding stent sizing and plaque assessment.

Technique

Rotational or phased array catheters produce high resolution intraluminal images. Pullback speed and calibration affect measurements.

Clinical Uses

Coronary and peripheral artery interventions for stent optimization and plaque characterization.

Limitations and Safety

Invasive with catheter related risks. Interpretation requires interventional expertise.

Cardiac CT Coronary CTA
4
Feb

Overview

Coronary CTA noninvasively visualizes coronary artery stenosis plaque morphology and cardiac anatomy with ECG gating to reduce motion.

Technique

ECG gating heart rate control and contrast timing are essential for diagnostic coronary imaging.

Clinical Uses

Coronary artery disease assessment calcium scoring and preoperative planning for structural interventions.

Limitations and Safety

Radiation and contrast exposure. Heart rate control and patient selection affect image quality.
