Ultrasound II: Endoscopic Ultrasound and FibroScan

Ultrasound II: Endoscopic Ultrasound and FibroScan

Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.
Endoscopic Ultrasound (EUS):

Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Background:

Acute coronary syndromes are linked to atherosclerotic plaque rupture.
Fibrous cap inflammation and thinning are implicated in plaque rupture.
In vivo confirmation in humans is limited by imaging resolution.

Purpose of the Study:

To provide an overview of intravascular optical coherence tomography (OCT) potential.
To highlight OCT's role in characterizing fibrous cap morphology and inflammation.
To discuss OCT's application in human coronary plaques.

Main Methods:

Utilizing intravascular optical coherence tomography (OCT).
Achieving micron-level axial and lateral resolution.
Visualizing micro-structural arterial wall changes.

Main Results:

OCT provides high-resolution imaging of the arterial wall.
Detailed visualization of fibrous cap thickness and morphology is possible.
OCT can identify inflammatory changes within coronary plaques.

Conclusions:

Intravascular OCT is a valuable tool for in vivo assessment of coronary plaques.
OCT enables detailed characterization of fibrous caps, aiding understanding of plaque rupture.
This imaging modality has significant potential in managing acute coronary syndromes.
