Dual-energy CT and coronary imaging

Area of Science:

• Cardiovascular Imaging
• Radiology
• Medical Technology

Background:

• Dual-energy computed tomography (DECT) offers advanced capabilities for coronary artery disease (CAD) assessment.
• Despite its potential, the clinical integration of DECT for CAD evaluation has been gradual.

Purpose of the Study:

• To review the evidence base for DECT in evaluating coronary artery disease (CAD).
• To illustrate practical applications of DECT in CAD.
• To identify challenges and knowledge gaps impeding DECT's clinical translation for CAD.

Main Methods:

• Literature review of studies on DECT for coronary artery disease.
• Analysis of clinical evidence and practical case examples.
• Identification of barriers to clinical adoption.

Main Results:

• DECT provides valuable insights into coronary artery plaque characterization and stenosis assessment.
• Illustrative cases demonstrate DECT's utility in complex CAD scenarios.
• Key challenges include standardization, radiation dose, and cost-effectiveness.

Conclusions:

• DECT holds significant potential for improving coronary artery disease evaluation.
• Addressing current challenges is crucial for broader clinical implementation.
• Further research is needed to optimize DECT protocols and validate its long-term clinical impact in CAD.
