Ultrasound Sonography

A diagnostic scan to image the anatomy of the abdominal organs, to check for anomalies and monitor fetal growth.

What is an Ultrasound?

An Ultrasound scan or a Sonography is a diagnostic technique that exposes the body to high-frequency sound waves to produce images of the internal anatomical structures. The ultrasound technique captures images in real-time, so that they can display the movement of the internal organs and blood flowing through the vessels.

Modern ultrasound technology has grown immensely, giving rise to various types of advanced techniques for accurate diagnosis. 3D ultrasound converts sound waves into 3D images to enhance the image quality. 4D ultrasound is a 3D ultrasound in motion. A Doppler ultrasound evaluates the blood flow through the major arteries and the veins in the abdomen, limbs, and neck. Based on their applications, Dopplers can be classified into Spectral, Colour, or Power Doppler scans.

Krishna Scans boasts powerful ultrasound scanning machines and is manned by a team of dedicated, trained, and experienced professionals.

1. Should I worry about any risks or side effects of an Ultrasound Sonography test?
No. An ultrasound is a painless, non-invasive and radiation-free diagnostic procedure. Since it is very safe, ultrasound sonography is the most preferred procedure to assess the fetal growth in pregnant women. Although doctors haven't ruled out long-term effects, there is no proof that the ultrasound is harmful to the fetus.
2. Why do doctors recommend ultrasound sonography?
Doctors will prescribe an ultrasound test to assess the function of all the major organs in the abdominal cavity, such as:
  • Pancreas
  • Intestines
  • Liver
  • Spleen
  • Kidneys
  • Gall bladder
3. What are the limitations of an ultrasound scan?
Ultrasound waves can only penetrate soft tissues. They cannot penetrate the bones, which is why they are not used to take images of the skull and bones.
4. When does an ultrasound prove to be useful?
An ultrasound test is very beneficial to further evaluate the following symptoms:
  • Abnormal bleeding
  • Acute pain
  • Pelvic pain
  • Infection
  • Menstrual problems
  • Swelling
5. What happens during an Ultrasound scan?
First, our technician will apply an odourless, colourless gel to the area that will be scanned. An imaging transducer or probe will be used by our radiologist to image the area. A transducer works by capturing images of various organs when it is moved around. These images will appear on a monitor. Our radiologist will use the most useful diagnostic images to make his interpretations.
6. Why should women have a full bladder for a pelvic ultrasound?
A full bladder projects the uterus into a conducive position and accentuates it by moving the intestines and bowels out of the way. It also brightens up the pelvis and adequately visualises parts of the reproductive system.
