What Is Ultrasound Imaging Scan?

Ultrasound (US) is an imaging technique that depicts tissue using high-frequency sound pulses. In comparison to other modalities, it is a practical and adaptable medical imaging technique that frequently offers an extra or distinct characterisation of tissues.

A non-invasive medical imaging method called ultrasound aids in the diagnosis and treatment of specific illnesses by medical professionals. Ultrasound imaging does not employ ionising radiation, in contrast to CT or X-ray imaging. Rather, it creates images of the body’s organs and architecture using high-frequency sound waves.

How Does an Ultrasound Machine Function?

To help ensure a secure connection between the transducer and the skin during an ultrasound scan, a gel is applied directly to the skin. By doing this, air pockets that could prevent sound waves from entering the surrounding tissue are removed from the area between the transducer and the skin. Sound waves are reflected to the transducer when they strike thick structures such as the uterine wall and the foetus. After that, the transducer gathers the reflected sound waves and uses a data processor to convert them into a visual image. The image then appears on the screen.

Ultrasound Applications in Medicine

Many of the inner organs of the body can be examined with ultrasound. Additionally, it is employed in medical operations. The following are a few applications for the use of ultrasound:

  • Abdominal ultrasound is used to look at the pancreas, kidneys, liver, gallbladder, and spleen
  • Breast ultrasound is used to check for problems related to the breasts, such as cancer
  • Echocardiogram used to examine the heart’s dimensions, form, and movement
  • Ultrasound of the eyes is used to look for eye conditions such as iris melanoma
  • Assisted biopsies and fluid collection drainage using guided interventional procedures

Benefits of ultrasound

When comparing ultrasound to other medical imaging techniques, there are several benefits:

  • Ultrasound uses non-ionising sound waves
  • Given that it offers real-time imaging, it’s a useful tool for directing procedures like fluid aspiration and needle biopsies in medicine
  • Most individuals find ultrasound scans to be painless and mostly tolerable. There is rarely much discomfort associated with an ultrasound technique that involves inserting a transducer into a physical opening
  • It has no known long-term adverse effects

At Beacon Hospital, ultrasound is used to detect a wide range of pathological conditions such as tumours, kidney stones, gallbladder stones and breast examinations. Ultrasound exams are usually completed within 10 to 30 minutes, and patients can resume their normal activities immediately after the procedure. Our high-definition ultrasound equipment provides good visibility and contrast to view even very small structures in the imaging of growths or abnormalities.
