Mineralized structures (such as bones) or air-filled organs (such as the lungs) do not show up well on a sonogram.MLabs offers adult and pediatric blood drawing services at our University of Michigan Health System locations. Ultrasound is most useful for looking at organs and structures that are either uniform and solid (such as the liver) or fluid-filled (such as the gallbladder). ![]() ![]() Pictures or videos of the ultrasound images may be made for a permanent record. The picture produced by ultrasound is called a sonogram, echogram, or ultrasound scan. A computer analyzes the reflected sound waves and converts them into a picture that is displayed on a TV screen. The transducer sends out high-pitched sound waves (above the range of human hearing) that are reflected back to the transducer. A small, handheld instrument called a transducer is passed back and forth over the area of the body that is being examined. It does not use X-rays or other types of possibly harmful radiation.įor ultrasound testing, gel or oil is applied to the skin to help transmit the sound waves. Ultrasound is a test that uses reflected sound waves to produce an image of organs and other structures in the body.

It also can study blood vessels, bones, and the spinal cord.Īn iodine dye (contrast material) is often used to make structures and organs easier to see on the CT pictures. The pictures are saved on a computer.Ī CT scan can be used to study any body organ, such as the liver, pancreas, intestines, kidneys, adrenal glands, lungs, and heart. One part of the scanning machine can tilt to take pictures from different positions. Each pulse lasts less than a second and takes a picture of a thin slice of the organ or area being studied. The CT scanner sends X-ray pulses through the body. A computed tomography (CT) scan uses X-rays to make detailed pictures of structures inside of the body.ĭuring the test, you lie on a table that is attached to the CT scanner, which is a large doughnut-shaped machine.
