What can ultrasound not detect? Ultrasound images are not as detailed as those from CT or MRI scans. Ultrasound cannot tell whether a tumor is cancer. Its use is also limited in some parts of the body because the sound waves can’t go through air (such as in the lungs) or through bone.
Beside this, What do red spots on an ultrasound mean? By definition, flow towards the transducer is depicted in red while flow away from the transducer is shown in blue. Different shades of red and blue are used to display velocity. Lighter shades of color are assigned to higher velocities.
Can you see a cyst on an ultrasound?

Do ultrasound techs know what they are looking at?
“Plenty of patients ask, but techs should not give information and should not even react to what they’re seeing on the image,” Edwards said. “They aren’t doctors, and while they do know how to get around your anatomy, they aren’t qualified to diagnose you.”
What do you call a person who does baby ultrasounds?
A diagnostic medical sonographer, also known simply as a sonographer, uses imaging equipment and soundwaves to form images of many parts of the body, known as ultrasounds. They are trained to acquire and analyze these sonographic images. These images are used to help doctors diagnose and treat many medical conditions.
Why did my ultrasound hurt?

What does yellow mean on ultrasound?
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.
