Area of Science:

  • Medical Imaging
  • Diagnostic Ultrasound
  • Vascular Imaging

Context:

  • Doppler sonography is a standard imaging technique.
  • Real-time imaging of blood flow is crucial for diagnosis.
  • Limitations exist in current Doppler techniques for complex flow visualization.

Purpose:

  • To introduce angiodynography, a novel system integrating Doppler sonography with advanced computerised techniques.
  • To enable real-time, color-coded visualization of blood vessels within standard ultrasound images.
  • To display both stationary tissue structures and dynamic blood flow information simultaneously.

Summary:

  • Angiodynography utilizes a new computerised method to display pulse echo signals (grey scale for tissue) and Doppler shifts (color for blood flow) at each point on an ultrasound plane.

  • The system was evaluated in 453 patients, successfully obtaining flow measurements in the carotid artery, jugular vein, renal transplants, thyroid, testis, and urethra.
  • Pathological flow velocities indicative of stenosis, tumors, and diffuse parenchymal alterations were effectively visualized.

    • Impact:

    • Provides enhanced visualization of vascular structures and hemodynamics.
    • Offers a new tool for diagnosing a range of vascular pathologies.
    • Potential to improve diagnostic accuracy and patient management in various clinical settings.
