Knowledge point

Molecular ultrasonography (ultrasound molecular imaging)

The future of contrast ultrasonography is in molecular imaging with potential clinical applications expected in cancer screening to detect malignant tumors at their earliest stage of appearance. Molecular ultrasonography (or ultrasound molecular imaging) uses targeted microbubbles originally designed by Dr Alexander Klibanov in 1997; such targeted microbubbles specifically bind or adhere to tumoral microvessels by targeting biomolecular cancer expression (overexpression of certain biomolecules occurs during neo-angiogenesis or inflammation processes in malignant tumors). As a result, a few minutes after their injection in blood circulation, the targeted microbubbles accumulate in the malignant tumor; facilitating its localization in a unique ultrasound contrast image. In 2013, the very first exploratory clinical trial in humans for prostate cancer was completed at Amsterdam in the Netherlands by Dr Hessel Wijkstra.

In molecular ultrasonography, the technique of acoustic radiation force (also used for shear wave elastography) is applied in order to literally push the targeted microbubbles towards microvessels wall; firstly demonstrated by Dr Paul Dayton in 1999. This allows maximization of binding to the malignant tumor; the targeted microbubbles being in more direct contact with cancerous biomolecules expressed at the inner surface of tumoral microvessels. At the stage of scientific preclinical research, the technique of acoustic radiation force was implemented as a prototype in clinical ultrasound systems and validated in vivo in 2D and 3D imaging modes.

Color-flow imaging

Color-flow imaging is an enhanced form of Doppler ultrasound technology. In a procedure similar to duplex ultrasound, it uses color to highlight the direction of blood flow. Vessels in which blood is flowing are colored red for flow in one direction and blue for flow in the other, with a color scale that reflects the speed of the flow.It can clearly understand the anatomical shape and activity of large blood vessels, and can visually display the direction, speed, range of blood flow, and whether there are blood flow disorders and abnormal pathways. The speed of blood flow determines the reflection frequency, which is represented by amplitude beam in spectral Doppler. The velocity of blood flow is fast, and the amplitude on the spectrum curve is high; the velocity of blood flow is slow, and the amplitude on the spectrum curve is low, so amplitude can accurately calculate the velocity of blood flow. Color Doppler images are displayed with different brilliance.
