Myocardial perfusion scintigraphy: past, present and future.

Area of Science:

• Cardiovascular Imaging
• Nuclear Medicine
• Ischemic Heart Disease

Background:

• Radionuclide myocardial perfusion scintigraphy (MPS) is the primary functional cardiac imaging technique for ischemic heart disease (IHD).
• Despite emerging alternatives, MPS remains widely adopted due to extensive supporting literature and proven prognostic value.
• The technique has undergone significant evolution, enhancing reliability and providing crucial ventricular functional data.

Purpose of the Study:

• To review the established role and future prospects of MPS in assessing IHD.
• To highlight technological advancements and new radiopharmaceutical applications in nuclear cardiology.
• To emphasize the continued importance of nuclear medicine in cardiac diagnostics and patient stratification.

Main Methods:

• Review of existing literature on myocardial perfusion scintigraphy.
• Discussion of technological advancements in SPECT and PET imaging.
• Exploration of novel radiopharmaceutical agents and their applications.

Main Results:

• MPS is a robust and reliable method for IHD assessment and prognosis.
• Hybrid imaging (SPECT/CT, PET/CT) and improved camera technology enhance MPS capabilities.
• New radiotracers show promise for evaluating cardiac failure and acute chest pain.

Conclusions:

• MPS will remain an essential tool for IHD investigation, complemented by hybrid imaging.
• Nuclear medicine cardiac imaging plays a vital role in diagnosis, risk stratification, and prognosis.
• Future developments will expand the scope of nuclear cardiology to broader patient populations and conditions.
