What are the different ultrasound techniques used in medical imaging?

There are several ultrasound techniques, including 2D, 3D, Doppler, and elastography. Each serves different diagnostic purposes.

Can you explain how Doppler ultrasound works?

Doppler ultrasound measures the change in frequency of sound waves as they bounce off moving objects, like blood cells, to assess blood flow.

What is the difference between 2D and 3D ultrasound?

2D ultrasound provides flat images, while 3D ultrasound creates a three-dimensional view, offering more detailed visualization of structures.

Are there any risks associated with ultrasound techniques?

Ultrasound is generally considered safe with no known risks, as it uses sound waves rather than ionizing radiation.

How is elastography different from traditional ultrasound?

Elastography assesses tissue stiffness, providing information about the elasticity of organs, which can help in diagnosing conditions like liver fibrosis.
