Summary
X-ray computed tomography (CT) enables detailed imaging for quantifying coronary calcification, a key indicator of coronary artery plaque. This review covers the biology, CT applications, and clinical use of this imaging technique.
Area of Science:
- Radiology and Medical Imaging
- Cardiovascular Disease Research
- Biomedical Engineering
Background:
- X-ray computed tomography (CT) offers high-definition imaging for various body parts.
- CT has emerged as a valuable tool for quantifying coronary calcification over the past decade.
- Coronary calcification is a well-established surrogate marker for coronary artery atheromatous plaque.
Purpose of the Study:
- To detail the pathophysiology of atherosclerotic disease.
- To explain the principles of using CT for defining atherosclerotic plaque.
- To discuss the technical, engineering, and clinical application challenges and advancements in CT-based plaque assessment.
Main Methods:
- Review of existing literature on CT imaging for coronary calcification.
- Discussion of Electron Beam Tomography (EBT) and Multi-Detector CT (MDCT) methodologies.
- Analysis of technical and engineering aspects relevant to CT plaque quantitation.
Main Results:
- CT, particularly EBT and MDCT, allows for the quantitative assessment of coronary calcification.
- Numerous publications support the use of CT for evaluating coronary artery plaque burden.
- The chapter synthesizes data primarily from EBT studies.
Conclusions:
- CT imaging provides a robust method for assessing coronary artery disease burden through calcification quantitation.
- Understanding the patho-biology and technical nuances of CT is crucial for accurate clinical application.
- CT holds significant promise for the clinical management of atherosclerotic disease.
