Sonography or Ultrasound imaging is a harmless and non-invasive medical test, which allows physicians to diagnose the medical condition of the patient without unnecessary pricking of the skin or piercing of the body parts.
What is Sonography (Ultrasound):
Ultrasound imaging, commonly called sonography involves exposing body parts to high-frequency sound waves to see images of the inner parts of the body. Examination by ultrasound, as opposed to X-rays, never involves the use of ionizing radiation. Images are captured in real-time.
Types Of Ultrasound:
The usual Sonography or Ultrasound examination is made with a transducer (ultrasound probe) on the skin. Although, sometimes the technicians and doctors can get a much better image by inserting the probe into one of the body’s natural openings:
- Transvaginal ultrasound: Inserting the probe into the vagina allows the examination of the uterus and the ovary
- Transrectal ultrasound: Inserting the probe into the rectum allows the examination of the prostate
- Transesophageal echo: Inserting the probe into the esophagus to allows the examination of the heart and the esophagus
Uses of Ultrasound imaging:
It helps in examine the internal body organs including:
- The liver
- The bladder
- The pancreas
- The eyes
- The spleen
- The heart
- Glands, like the thyroid and parathyroid
- The reproductive organs, including ovaries, uterus, and covering of the testicles (scrotum)
Ultrasound imaging can also be applied to guide needles into the body for obtaining biopsies.
Benefits and risks
- Most ultrasound examinations are non-invasive (no needles or injections), meaning that they are painless.
- Ultrasound testing is less expensive, widely available and is very easy to carry out.
- Ultrasound Imaging never exposes you to the cell damage.
- Soft tissues that are hard to see on images from X-rays can be examined on ultrasound scans.
- With real-time imaging, an ultrasound is an excellent tool to use as a guide in minimally invasive procedures, such as needle aspiration and needle biopsies.
There are no reported harmful effects of a standard diagnostic ultrasound.
- The bowel and any organ hidden by the intestine cannot be examined because gas or air blocks ultrasound waves.
- Scanning overweight patients can be challenging because of the fat tissue.
- Ultrasound waves cannot easily pass through the bones in the body.
Ultrasound is a painless and non-dangerous diagnostic tool. It can help in examining internal body organs.
