Advanced ultrasound techniques improve urological imaging. New methods like panorama sonography and microvascular imaging (MVI) enhance visualization of tissue perfusion for better diagnosis in andrology and uro-oncology.

Area of Science:

  • Urology
  • Medical Imaging
  • Sonography

Background:

  • Conventional 2D ultrasound has limitations in visualizing complex anatomical structures and microcirculation.
  • Advancements in ultrasound technology are crucial for improving diagnostic accuracy in urological conditions.

Purpose of the Study:

  • To present novel sonographic techniques and their operational principles in urology.
  • To highlight how these advanced methods enhance image resolution, detail visualization, and perfusion assessment.

Main Methods:

  • Utilization of broadband ultrasound scanners and digital beam formers.
  • Implementation of panorama sonography, spatial compound sonography, and 4D (real-time) imaging.
  • Application of second harmonic imaging (tissue harmonic imaging and contrast harmonic imaging) with ultrasound contrast agents (UCA).

  • Employing microvascular imaging (MVI) for visualizing microcirculation perfusion.

    • Main Results:

    • Improved spatial resolution and line density in ultrasound imaging.
    • Enhanced visualization of wide lateral regions and fine details in B-mode.
    • Real-time 4D imaging allows visualization of unrestricted imaging planes.
    • Successful assessment of tissue hemoperfusion using harmonic imaging and MVI, including pathological patterns.

    Conclusions:

    • New sonographic techniques offer significant improvements over conventional methods in urology.
    • These advancements provide novel possibilities for assessing perfusion in andrology and uro-oncology.
    • Advanced ultrasound imaging is key to understanding and diagnosing urological pathologies more effectively.
