Area of Science:

  • Cardiology
  • Medical Imaging
  • Nuclear Medicine

Background:

  • Assessing myocardial perfusion, ischemia, and viability is crucial for ischemic heart disease (IHD) patients.
  • Nuclear imaging techniques like single-photon emission computed tomography (SPECT) and positron emission tomography (PET) are established methods.
  • Recent use of "perfusion" with other modalities like echocardiography, MRI, and CT has created terminological ambiguity.

Purpose of the Study:

  • To clarify the definitions of "perfusion", "ischemia", and "viability" in the context of myocardial assessment.
  • To critically evaluate the accuracy and limitations of various cardiac imaging modalities.
  • To address the terminological uncertainty surrounding "perfusion" imaging in cardiology.

Main Methods:

  • Literature review and critical analysis of existing studies.

  • Comparison of different imaging modalities based on their ability to assess myocardial perfusion, ischemia, and viability.
  • Evaluation of the kinetic properties of indicators and visualized myocardial processes.

    • Main Results:

    • Established definitions for "perfusion", "ischemia", and "viability" are presented.
    • SPECT and PET are highlighted as key methods for quantitative assessment.
    • The review identifies discrepancies in how "perfusion" is applied across different imaging techniques.

    Conclusions:

    • Accurate definitions are essential for correct interpretation of cardiac imaging results.
    • Understanding the specific capabilities of each modality prevents misinterpretation of myocardial status.
    • Standardized terminology is needed to improve diagnostic accuracy in ischemic heart disease management.
