Summary
Colour Doppler ultrasonography visualizes real-time blood flow using B mode ultrasound and Doppler technology. This non-invasive technique aids in maxillo-facial surgery by displaying moving structures in color.
Area of Science:
- Medical Imaging
- Diagnostic Ultrasound
- Vascular Imaging
Background:
- Real-time B mode ultrasound provides anatomical imaging.
- Doppler ultrasound detects blood flow velocity and direction.
- Combining these technologies offers enhanced visualization of vascular structures.
Purpose of the Study:
- To describe the technique of Colour Doppler Ultrasonography.
- To present experiences from 63 examinations.
- To discuss the clinical application in maxillo-facial surgery.
Main Methods:
- Integrating real-time B mode ultrasound with Doppler signal processing.
- Interrogating returning signals for amplitude and frequency.
- Displaying non-moving structures in grayscale and moving structures in color (red/blue) based on direction and velocity.
Main Results:
- Colour Doppler ultrasonography successfully visualizes blood flow in real-time.
- The technique differentiates moving from non-moving structures.
- Demonstrated utility in 63 examinations.
Conclusions:
- Colour Doppler ultrasonography is a valuable non-invasive diagnostic tool.
- The technique shows significant potential for clinical application in maxillo-facial surgery.
- This method offers simple, real-time assessment of vascularity.
