What does red or blue mean on an ultrasound?
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.
What does yellow mean on an ultrasound?
high flow turbulence
A third color, usually green or yellow, is often used to denote areas of high flow turbulence. These colors are user-definable and may be reversed, however this is generally inadvisable as it may confuse later readers of the images.
What does black mean on ultrasound?
On sonography imaging liquids appear black because they are “anechoic”. It means that the ultrasound wave goes through them without emitting any return echo .
What does white mean on an ultrasound?
Highly dense tissues such as bone or kidney stones readily reflect echoes and, therefore, appear bright white on an ultrasound. Air, such as in the bowel, also readily reflects echoes. The edge of the bowel, therefore, appears white on an ultrasound.
What color are tumors on ultrasound?
For example, most of the sound waves pass right through a fluid-filled cyst and send back very few or faint echoes, which makes them look black on the display screen. But the waves will bounce off a solid tumor, creating a pattern of echoes that the computer will show as a lighter-colored image.
Are tumors White on ultrasound?
For example, most waves pass through a fluid-filled cyst and send back very few or faint echoes, which look black on the display screen. On the other hand, waves will bounce off a solid tumor, creating a pattern of echoes that the computer will interpret as a lighter-colored image.
Can a radiologist tell if a mass is cancerous?
Some masses can be watched over time with regular mammograms or ultrasound to see if they change, but others may need to be checked with a biopsy. The size, shape, and margins (edges) of the mass can help the radiologist decide how likely it is to be cancer.
What are the blue and red spots on an ultrasound?
Blood flow will be recognized by red and blue signals. This is called continuous Doppler. In most circumstances, red represents blood moving toward you and blue represents blood moving away from you. Always ask your physician to explain the results of your ultrasound.
Does a sonogram show cancer?
Ultrasound Results: Breast Sonogram. While cysts are typically not cancerous, a solid lump may be a cancerous tumor. Healthcare professionals also use this diagnostic method to help measure the exact size and location of the lump and get a closer look at the surrounding tissue.
What is color Doppler ultrasound?
Color Doppler Ultrasound helps to determine integrity of testis following trauma, detects undescended testicles in cord which may be impalpable by clinical examination. Pozniak and Allan present this reference on applications of Doppler ultrasound.
