Study Notes

Ultrasound

Uses high-frequency sound waves to create images of internal body structures
Commonly used for fetal development, abdominal and pelvic organs, muscles and tendons, heart and blood vessels
M-Mode: High frame rate, useful for fast-moving objects, motion function.
B-Mode (2D): Depth on the x-axis, amplitude on the z-axis
Doppler Mode: Visualizes blood flow

3D Ultrasound

Acquires volume data set to create a 3D image
Used to see the face of a baby
Can reliably identify fetal gender

4D Ultrasound

Similar to 3D, but provides a live video of the baby
Shows the movement of baby's body parts, like the heart walls

Elastography

Non-invasive imaging technique that assesses the stiffness of organs and structures
Commonly used to assess tissue health

Computed Tomography (CT Scan)

Combines X-rays and computer technology to create detailed images of the body
Produces images of bones, muscles, fat, organs, and blood vessels
Provides more detail than standard x-rays

Magnetic Resonance Imaging (MRI)

Uses strong magnetic fields and radio waves to create detailed images of the body

Ultrasound

Ultrasound uses high-frequency sound waves to create images of internal body structures.
It is commonly used for studying a developing fetus, abdominal and pelvic organs, muscles and tendons, heart and blood vessels.
M-mode displays fast moving objects, like the heart's function with a high frame rate.
B-mode or 2D imaging produces images with depth on the x-axis and amplitude on the z-axis.
Doppler mode is used for blood flow visualization, where the frequency shift, caused by movement, is observed.

3D Ultrasound

3D Ultrasound captures a volume data set allowing for images like the face of a baby and reliable fetal gender diagnosis.

4D Ultrasound

4D Ultrasound is similar to 3D, but displays a live-streaming video of the baby inside the womb.
The images show the movement of the baby's body parts, such as the heart walls.

Elastography

Elastography is a non-invasive imaging technique assessing organ stiffness, which may indicate health issues.
It is commonly used to assess the stiffness of organs and tissues.

Computed Tomography (CT)

CT scans use X-rays and computer technology to create detailed images of the body's interior.
They provide detailed images of bones, muscles, fat, organs, and blood vessels.
CT scans offer greater detail than standard X-rays.

Magnetic Resonance Imaging (MRI)

MRI uses strong magnetic fields and radio waves to create detailed images of the body's interior.
