Area of Science:

  • Cardiovascular Imaging
  • Diagnostic Ultrasound

Background:

  • Myocardial contrast echocardiography (MCE) has advanced significantly over the past two decades.
  • It is now a clinically relevant tool for diagnosing and evaluating coronary artery disease (CAD).

Purpose of the Study:

  • To summarize the current state and future potential of MCE in cardiovascular diagnostics.
  • To highlight the role of ultrasound contrast agents in assessing myocardial perfusion.

Main Methods:

  • Development of specialized ultrasound contrast agents (microbubbles) that act as red blood cell tracers.
  • Utilizing dedicated ultrasound imaging modalities for myocardial perfusion assessment.

Main Results:

  • MCE accurately identifies acute and chronic myocardial infarction, viable myocardium, and significant coronary stenoses.
