an imaging method in which high-frequency sound waves are used to outline a part of the body. The sound wave echoes are picked up and displayed on a television screen. This painless method is sometimes useful in distinguishing fluid-filled cysts from solid tumors. It is sometimes used to guide needle biopsy of breast abnormalities too small to feel.

A technique that uses high frequency sound waves to find position, structure and function of anatomical structures. The sound waves bounce off tissues and produce echo. The echo is then converted to picture and viewed on a video screen. This is a noninvasive technique that can distinguish between a solid tumor and a cyst containing fluid.

Noninvasive diagnostic technique for visualizing the internal structures of the body by means of sound (echo) reflections; ultrasound.

A test that uses sound waves to view internal structures; it can reveal whether urine is retained in the bladder after urination.

The use of high-frequency sound (usually 1–10 MHz range) to generate images of the human body.

A noninvasive visualization technique that uses high frequency sound waves (ultrasound) aimed at a structure inside the body to produce an image (sonogram) of the internal structure or feature of interest.

View of deep structures of the body by recording reflections or echoes of pulses of ultrasound waves directed into tissues. Sound waves are transmissible in liquid and solid.

a display of ultrasonic echoes used to examine soft tissue.

A procedure in which sound waves (called ultrasound) are bounced off tissues and the echoes produce a picture (sonogram).

using the reflections of high-frequency sound waves to construct an image of a body organ (a sonogram); commonly used to observe fetal growth or study bodily organs

A radiological procedure performed either transvaginally or abdominally that uses sound waves to assess uterine fibroids, ovarian cysts, pelvic masses, pelvic pain, and other gynecologic problems. It is also used to track the development of egg-bearing follicles during ovulation induction.

the use of ultrasound to produce an image of an organ or tissue

Recordings of the echoes of ultra-sound waves sent into the eye and reflected from the structures inside the eye or orbit. It allows one to detect and localize tumors and retinal detachments.

detection or measurement of deep structures by measuring the reflection or transmission of high-frequency sound waves

A technique that uses ultrasound to obtain visual images of the urinary tract for the purpose of assessing its anatomic status.

The use of high frequency sound waves to examine internal body structures, such as a fetus contained in the uterus. An ultrasound examination is also known as a sonogram.

The diagnostic use of ultrasonic waves (acoustic frequencies above the range audible to the human ear) to visualize internal bodily structures and organs.

A diagnostic technique in which high-frequency sound waves are bounced off tissues inside the body and converts the echoes into pictures. Tissues of different densities reflect sound waves differently.

Sometimes used in combination with mammography, ultrasonography uses high-frequency sound waves to determine the physical nature of a lump.

UL-trah-SO-nah-gra-fee] The use of sound waves to examine the eye and orbit. Ultrasonography is commonly used to measure the size of tumors.

Imaging deep structures of the body

MS = The visualization of deep structures of the body by recording the reflections of echoes of pulses of ultrasonic waves directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz. AN = GEN only; prefer /ultrasonogr with organs & diseases: Manual 19.7+, 19.8.77; ultrasonic or sonographic imaging of organs is organ /ultrasonogr; X ref ECHOTOMOGRAPHY is seen in foreign lit: if so, use "ultrasonography" or "ultrasonic diagnosis" or "ultrasonic imaging" in translations & not "echotomography"; ECHOCARDIOGRAPHY & ECHOCARDIOGRAPHY, DOPPLER & ECHOENCEPHALOGRAPHY are also available; DF: ULTRASONOGR UI = D014463

A technique that uses sound waves that cannot be heard by humans to produce pictures of areas inside the body. The pictures created by a computer that analyses the echoes produced by the waves as they bounce off tissues.

a method of visualizing the internal parts of the body, or a fetus within the uterus, using sound waves.

Provides a pictorial display of anatomical structures, using high-frequency pulse-echo techniques.

The use of sound waves to image the deep structures of the body. Often used during pregnancy and for the diagnosis of many diseases, including cancer. Also called sonography or ultrasound imaging.

A process used to obtain "pictures" of the developing embryo using ultrasound.

( see also): An exam in which sound waves are bounced off tissues and the echoes are converted into a picture (sonogram).

A noninvasive technique that uses a skin probe emitting sound waves (ultrasound). Thus, visual images of the internal organs, e.g., the urinary tract, can be obtained for the purpose of assessing its position.

A test in which sound waves are bounced off body tissue, and the echos are converted into a picture, for the purpose of medical examination or diagnosis, that are viewed on a monitor.

(UL-tra-son-OG-ra-fee): A study in which sound waves (called ultrasound) are bounced off tissues and the echoes are converted into a picture (sonogram).

A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasound.

Commonly called "ultrasound." An imaging technique that uses high-frequency sound waves to create an image. During pregnancy, ultrasonography can be used to provide an image of the developing fetus, including the entire body, organs and surrounding tissue.

Method of using sound wave reflections to obtain a representation of the developing fetus. Used to estimate gestational age and detect fetal physical abnormalities.

A test in which high-frequency sound waves, inaudible to the human ear, are transmitted through body tissues. The echoes are recorded and transformed into video or photographic images. Ultrasound is used to create images of soft tissue structures and can also detect blockages in the blood vessels. Ultrasound images help in the diagnosis of a wide range of diseases and conditions.

Process by which the reflection of high-frequency sound waves is used to develop an image of a structure.
