Summary
Microvascularization (MicroV) enhances transcranial ultrasound by visualizing weak blood flows and improving vessel shape reconstruction. This emerging technology offers superior morphological definition for intracranial vessels.
Area of Science:
- Neuroimaging
- Ultrasound Technology
- Vascular Imaging
Background:
- Transcranial Doppler (TCD) was developed for intracranial vessel velocimetric analysis.
- Traditional Color Doppler and Power Doppler techniques can overestimate intracranial vessel morphology, especially in thin vessels or at high depths.
- Advancements using contrast agents improved morphological studies by increasing signal-to-noise ratio.
Purpose of the Study:
- To review emerging technologies for Transcranial Color Coded Doppler Examinations.
- To highlight the potential of Microvascularization (MicroV) in transcranial ultrasound.
- To compare MicroV with existing Doppler techniques for intracranial vessel assessment.
Main Methods:
- Review of emerging Power Doppler technology: Microvascularization (MicroV).
- Analysis of MicroV's capability to visualize low and weak blood flows at high depths.
- Evaluation of MicroV's impact on vessel shape reconstruction and Circle of Willis imaging.
Main Results:
- MicroV allows visualization of weak blood flows and improves vessel shape reconstruction without overestimation.
- MicroV provides a global image of the Circle of Willis by analyzing Doppler signals.
- MicroV demonstrates a high signal-to-noise ratio, surpassing limitations of previous techniques.
Conclusions:
- MicroV is a promising Power Doppler technology for transcranial ultrasound analysis.
- It offers enhanced morphological definition of intracranial vessels compared to conventional methods.
- MicroV has significant potential for improving neurosonology assessments.

The Doppler effect and Doppler shift were named after the Austrian physicist and mathematician Christian Johann Doppler in 1842, who conducted experiments with both moving sources and moving observers. Consider an observer standing on a street corner, observing an ambulance with a siren sound passing by at a constant speed. The observer experiences two characteristic changes in the sound of the siren. Initially, the sound increases in loudness as the ambulance approaches and decreases in...

The Doppler effect has several practical, real-world applications. For instance, meteorologists use Doppler radars to interpret weather events based on the Doppler effect. Typically, a transmitter emits radio waves at a specific frequency toward the sky from a weather station. The radio waves bounce off the clouds and precipitation and travel back to the weather station. The radio frequency of the waves reflected back to the station appears to decrease if the clouds or precipitation are moving...

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
