What is ultrasound?

Ultrasound is used to create images of soft tissue structures, such as the gall bladder, liver, heart, kidney, female reproductive organs– and even of babies still in the womb. Ultrasound can also detect blockages in the blood vessels.

This helps the physician to find out the reasons for pain, swelling or any kind of infection in the body.

How is the test performed?

You will be asked to lie down and a clear water based conducting gel is applied over the abdomen to help with the transmission of sound waves.

The ultrasound transducer (a hand held probe) is then moved over the abdomen. You may be asked to hold your breath for short periods of time during the procedure. There may be varying degrees of discomfort from pressure as the transducer is moved from one area to another. The gel will be wiped off your skin after the test.

The whole examination takes usually less than 30 minutes except pregnancy scans (especially with multiple pregnancies).

Transvaginal Ultrasound involves the insertion of the transducer, a long probe, covered with a condom and a sterile lubricant that is inserted into the vagina. The probe will then be moved within the vaginal cavity to scan the pelvic structures.

In Transrectal Ultrasound a protective cover is placed over the transducer lubricated and then placed into the rectum to obtain the images of the prostarte gland.

Doppler Ultrasonography helps to detect moving blood cells or other moving structures and measure their speed and direction of movement. It helps in evaluating blood flow through the major arteries and veins of the arms, legs and neck.
