As technology advances and new diagnostic techniques are developed, ultrasonography is a useful tool to provide detailed and accurate images of the different organs and internal structures of the human body. Ultrasonography, a special subset of ultrasonography, uses ultrasound waves to produce images of internal organs as well as those of soft tissues.
Benefits for medical specialists when using ultrasound scanner:
These images provide doctors with useful information about normal anatomy to help evaluate and identify the presence of injuries or abnormalities; ultrasounds are composed of high-frequency sound waves that cannot be perceived by the human ear.
This type of sound is reflected by tissues, providing a map or image showing the internal contours and location of different organs; ultrasound can also be used to measure the amount of fluid within a particular structure, which is useful for controlling the flow within the body.
The different parts of the body can be seen very clearly
The organs and structures that can be imaged with ultrasonography include the kidneys, liver, spleen, testes, uterus and ovaries, blood vessels, gallbladder, muscles, brain, thyroid, prostate, and heart, among others.
Depending on the area best viewed, different devices are recommended. For example, a device called transrectal ultrasonography is used to image the prostate, whereas transvaginal ultrasonography is best used to view the uterus and ovaries.
How images and their quality are obtained by using a sound scanner
The ultrasound image usually obtained is black and white, and is obtained by echo signals that bounce off different structures, which are separated from the surface and background of the image.
The structures of the image are differentiated in principle by the intensity of the returned signal; in addition, the acoustic behavior of the body’s soft tissues also influences the appearance of the image.
The most outstanding advantages for specialist physicians in detecting abnormalities are
In general, organs and structures are expected to show a clear and sharp image if they are in the normal anatomy; organs should show clear boundaries, a homogeneous structure, adequate presence of fluid and absence of masses, bulging, cancer, tumors, tissue hardening, or organ division.
In some cases, seeing an abnormality on the image can help doctors diagnose or pinpoint an unknown condition; sometimes these abnormalities are directly related to an underlying disease, so doctors do tests to confirm the presence of a disease.
For patients, detecting abnormalities by doctors is important
In conclusion, with the advent of ultrasonography, doctors can now visualize normal internal anatomy in a great deal of detail, this allows them to detect abnormalities early for treatment or, if necessary, apply appropriate examinations for diagnosis.
Ultrasonography allows improved visualization to provide better medical care.
