Area of Science:

  • Cardiovascular imaging
  • Medical ultrasound technology
  • Cardiac physiology

Context:

  • Echocardiography is established for quantitative intracardiac flow and pressure assessment.
  • Evaluating regional myocardial function currently relies on subjective interpretation.
  • Routine methods for estimating myocardial blood flow are lacking.

Purpose:

  • To provide an overview of emerging echocardiographic techniques for enhanced cardiovascular assessment.
  • To discuss advancements in imaging quality and objective functional measurements.
  • To highlight the potential of new modalities for quantifying myocardial blood flow and volume.

Summary:

  • Native second harmonic imaging enhances image quality.
  • Tissue Doppler provides objective regional myocardial function data, transformable into parametric images like strain rate imaging.
