Ultrasonography, more commonly known as usg, in short, has become the primary effective diagnostical imaging tool in the field of medical science to identify the cause of diseases. It helps in identifying pains, swellings, ruptures and also infections in the internal organs. From diagnosing superficial human internal structures such as tendons, muscles, breasts, thyroid glands, to deeper substantive organs like liver and kidney, ultrasonography has proven to be an efficient means of body-imaging in modern times with over multiple advantages to consider. And not to forget, this technique has been consistently used as the imaging technique for babies in the womb.

How does ultrasound imaging works

Ultrasonography is a noninvasive medical examining technique. That is, the process does not involve the introduction of medical instruments into the body. Hence the technique is considered to be both safe and painless. The technique uses sounds that are particularly high in frequency (the frequency well over 20000 Hz that is higher than human audible limits) and is sent to the tissues of the internal structures. For the high-frequency sound wave transmission, a transducer, which also goes by the name probe, will be used. when this transducer is brought in contact with the skin, inaudible, high-frequency sound waves will be transmitted to the tissues of body organs. as the sound waves make their way through the internal body, they tend to bounce back when they come across a hurdle. This results in the change in the pitch and direction if the sound waves. These changes, however small, will be recorded by the same transducer. Because here the transducer is responsible for not only the sound wave transmission but also for collecting the sound that reflects back from the tissues. The echoes thus obtained are used to record the image. These images, which will be displayed on the computer, are known as sonograms.

The simple conduction of the test:

There are no special preparations to be made by the one who wishes to get examined. All thanks to being a noninvasive technique, this technique is considered harmless. At times, when the test is carried out on tender organs, or organs with natural openings, discomfort can be observed. Nevertheless, it is not substantial, and one can easily overcome it.

In order to ensure the proper contact of the transducer with the skin, ultrasound gel is used. With the help of this, air pockets within the transducer and skin can be eliminated and hence it results in uniform physical contact. Then, the probe will be moved over the skin back and forth until satisfactory imaging is done. Once done, the gel will be wiped off completely.

Typically, the time taken for imaging is 30 minutes, but it can vary significantly depending on the condition. Once completed, one can easily resume back to daily normal activities.

The benefits of ultrasonography

  • To expand on the advantages, usg can be done without having to worry about the harmful ionic radiations. This can be regarded as a staggering merit, as these ionic radiations are the prominent reason why people, in need of medical imaging, usually refrain from diagnostic body imaging
  • Furthermore, the images are produced in real time, making the diagnosis period substantially simpler and less tedious
  • The quality of the images of the soft tissues is considered to be superior to that of X-Ray images
  • The cost, on the other hand, is known to be comparatively lower than other known techniques such as Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET)
  • And to top all of that, usg test at home is also possible as the diagnosing setups are easily portable

The risks to be considered:

  • The quality of the imaging drops significantly if it involves the imaging of air-filled bowels, as the transmission of ultrasound waves is disrupted by air or gas
  • Imaging of bones is not good, as the waves cannot penetrate into them unless it is the babies’ bones which are being examined
  • Skilled sonographers are necessary for professional testing and interpretation of results.


Ultrasonography is indeed the imaging technique that one must adopt for easy spotless, hassle-free medical imaging, Given the benefits and the terrific imaging of vital body organs such as gallbladder, heart, liver, and kidney, and also the spine, brain, and hips of unborn infants, one can’t go wrong with this imaging process.
