Imaging techniques for coronary artery disease: current status and future directions

Area of Science:

• Cardiovascular Imaging
• Radiologic Technology
• Diagnostic Cardiology

Background:

• Coronary artery disease (CAD) evaluation relies on various imaging modalities.
• Current techniques include sestamibi SPECT, PET, MRI, and contrast perfusion echocardiography (CPE).
• Assessing diagnostic accuracy and ventricular function are key considerations.

Purpose of the Study:

• To review the current status of advanced imaging techniques for CAD.
• To explore future directions and potential roles of SPECT, PET, MRI, and CPE.
• To evaluate their diagnostic accuracy, functional assessment capabilities, and cost-effectiveness.

Main Methods:

• Review of current literature on sestamibi SPECT, PET, MRI, and CPE for CAD.
• Comparative analysis of diagnostic accuracy and adjunctive capabilities.
• Projection of future trends and clinical utility based on technological advancements.

Main Results:

• Sestamibi SPECT is favored for its diagnostic accuracy and ventricular function assessment.
• Tissue attenuation correction is expected to enhance SPECT performance.
• PET offers advantages in specific cases but is unlikely for routine use due to cost.
• Cardiac MRI shows promise for comprehensive CAD evaluation.
• Contrast perfusion echocardiography (CPE) is a developing modality with significant future potential.

Conclusions:

• Sestamibi SPECT remains a leading radionuclide technique for CAD.
• Cardiac MRI and CPE are emerging modalities poised to play significant roles in future CAD testing.
• These advancements are expected to improve diagnostic efficacy and potentially cost utility in managing coronary artery disease.
