Quantitative Clinical Nuclear Cardiology, Part 1: Established Applications

Area of Science:

• Cardiovascular Imaging
• Nuclear Cardiology

Background:

• Single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is a standard for diagnosing coronary artery disease (CAD).
• Computer-aided quantitative assessment is crucial for standardizing SPECT MPI interpretation.
• Clinical adoption is driven by validated, user-friendly software platforms.

Purpose of the Study:

• To describe established quantitative tools for SPECT MPI.
• To guide clinicians on the routine use of these tools in patient management.
• To enhance the interpretation, clinical management, and therapy guidance for CAD patients.

Main Methods:

• Review of clinically established quantitative SPECT MPI software and algorithms.
• Focus on practical application and integration into diagnostic workflows.
• Discussion of how quantitative data informs clinical decision-making.

Main Results:

• Quantitative SPECT MPI provides objective assessment, improving diagnostic accuracy.
• Standardized interpretation protocols enhance reliability and reproducibility.
• Software pipelines facilitate widespread access to validated quantitative tools.

Conclusions:

• Routine use of quantitative SPECT MPI tools is essential for optimal CAD patient care.
• These tools empower clinicians with objective data for interpretation and management.
• Continued development and application of quantitative methods will advance cardiovascular imaging.
