Absolute quantification of myocardial blood flow

Area of Science:

• Cardiovascular imaging
• Nuclear medicine
• Medical diagnostics

Background:

• Positron emission tomography (PET) myocardial perfusion imaging is increasingly available.
• Absolute quantification of myocardial blood flow (MBF) provides crucial diagnostic and prognostic information.
• Visual assessment of myocardial perfusion is conventional but less informative than quantitative MBF.

Purpose of the Study:

• To review the clinical aspects of PET MBF quantification.
• To discuss emerging approaches for MBF quantification.
• To address the growing demand for accessible quantitative diagnostic methods.

Main Methods:

• Review of clinical applications of PET MBF quantification.
• Exploration of MBF quantification techniques using various imaging modalities.
• Discussion of advancements in quantitative diagnostic imaging.

Main Results:

• Quantitative MBF offers superior diagnostic and prognostic value compared to visual assessment.
• PET/CT has driven demand for more accessible quantitative MBF approaches.
• Alternative imaging modalities are being developed for MBF quantification.

Conclusions:

• Absolute MBF quantification is a valuable tool in clinical cardiology.
• Expanding MBF quantification methods beyond PET/CT is essential for wider adoption.
• Continued research into novel imaging techniques will enhance accessibility and utility.
