Ultra Sound / Colour Doppler

Ultrasound scans use high-frequency sound waves, which don’t involve a radiation dose to study a person’s internal body structures. Clarity performs full range of diagnostic ultrasound examinations including abdominal, pelvic, vascular, pediatric, musculoskeletal, obstetric and small part examinations.

Frequently Asked Questions

Here are common answers to clarify your questions.

Ultrasound scan is used to evaluate internal organs in the abdomen. An ultrasound scan is often used during pregnancy to obtain pictures of a baby in the womb. An ultrasound scan builds up pictures of organs and other areas inside the body from sound waves. These sound waves have a frequency beyond human hearing. An ultrasound scan doesn't use x-rays and is entirely safe. The ultrasound waves are sent inside the body by a small handheld sensor. The sensor is moved over the surface of the skin and it picks up the reflected sound waves as they bounce off various organs within the body. A computer, which is linked to the sensor, turns the sound waves into pictures that are viewed on a television screen. Photographs of these pictures can be taken.

Ultrasound scans are investigations that can be used to help doctors to make a diagnosis or assess the effects of treatment. Your doctor will recommend an ultrasound scan based on the type of disease you have and the information needed.

There is no radiation risk with ultrasound. It is considered to be very safe.

Scans of the upper abdomen usually require at least 4-6 hours of fasting. Overnight fasting may sometimes be required for better visualization of your gall bladder. Scanning of the pelvis requires you to have a full bladder. If your bladder is not full when you arrive for your scan, you will be advised by the assistant to drink water and wait until your bladder is full. Clean drinking water is available in water dispensers placed in the waiting area. You can also bring your own drinking water if you prefer.

When you arrive in the Ultrasound room you will be asked to lie on an examination couch. The lights from the room will be dimmed so that the pictures on the television screen can be seen more clearly. A gel will be applied onto your skin in the area to be scanned, such as the abdomen. The gel allows the sound waves to pass into the body. The sensor can also move over the skin more easily. The gel will be wiped off at the end of the scan.

There are two ways of scanning the pelvis for women. The first is through the abdomen. For this method a full bladder is essential to help produce good pictures. The second method uses a specially designed transducer, which is inserted into the vagina. This technique provides better, more accurate pictures of uterus and ovaries and avoids the discomfort of a full bladder.

A local anesthetic will usually be injected to numb the area and prevent discomfort. Ultrasound guides doctors to the correct place by enabling them to "see" inside the body. Then the doctor inserts a fine needle and syringe to draw off cells, fluid or tissue. The sample is sent to the laboratory for examination under a microscope.

Breast Sonography is a painless ultrasound procedure where the breasts are scanned with high frequency sound waves to produce pictures of the breast tissue. Ultrasound testing allows the Radiologist to determine whether a lump is solid tissue or a fluid-filled cyst.

Very dense breasts can often be seen better with ultrasound than with mammography. Exams for young patients and certain follow-up exams will be done primarily with ultrasound.

The same ultrasound equipment can be used to study the blood flow within arteries or veins. This study helps to find if there are blocks or narrowing in the arteries or veins.

NO! It is absolutely illegal for either the Radiologist or the sonology assistant to divulge the sex of the baby and any queries in this regard will not be entertained in our centre. Please remember that by trying to ascertain the sex of the baby, you are as much liable to be prosecuted by the law as much as any doctor/staff engaging in such unethical practices. Before a pregnancy scan you will be required to read and sign a consent form in which you agree not to enquire about the sex of the baby.

No, you only feel the gentle pressure of the sensor over your skin. If you are required to have an internal scan , the procedure will be explained to you by the female staff.

Most scans take between 10-30 minutes. However, repeat scanning after a gap may be required in selected cases, depending upon the complexity of the case

As soon as the scan is completed you may get ready to go home or back to your hospital if you are an inpatient. The gel can be removed before you get dressed. You may go to the toilet ,eat and drink as usual. There are no side effects to the ultrasound scan itself.

Usually the Radiologist will prepare a report which you can collect along with the pictures. This may take from a half an hour to two hours.
