What is an ultrasound?
Ultrasound is a test that has been largely associated with pregnancy. It is rather a common sight to carry out ultrasound test in the hospitals with ultrasound laboratory in Delhi in order to find out the gender of the baby and also to identify the anomalies or birth defects early on. But fetal imaging is only one of the common uses for ultrasounds.
How does the procedure work?
An ultrasound can develop a live image of the inside of the body using sound waves in an ultrasound lab in Delhi. This is done by using a tool called a transducer which produces high frequency sounds that human ears cannot process and then uses the echoes to discover all the information about the organs and tissues inside. This information is then shown on a computer screen. It takes a trained ultrasound technician to be able to perform the test properly. Once the test is done, a radiologist or doctor can interpret the images in order to diagnose conditions.
What is an ultrasound used for?
An ultrasound has many different uses, but here are the most common:
- Pregnancy: In the beginning of the pregnancy an ultrasound image can be used to confirm pregnancy and reveal due dates. As the pregnancy progresses it can be used to determine the presence of twins and reveal the gender of the baby. And ultrasound can also be used to find out any problems like birth defects, breech positioning, ectopic pregnancies, issues with the placenta, and more.
- Diagnostics: Ultrasound imaging is often used to find out issues that include the heart and blood vessels, gallbladder, kidneys, bladder, ovaries, uterus, liver and basically any organ inside the body. This procedure is also used to perform a thyroid biopsy or a breast biopsy to determine if there is a presence of cancer. Doctors also use this imaging to help guide the biopsy needle through the skin to a very precise area in order to retrieve tissue to test.
What are the different types of ultrasound?
Most of the time an ultrasound can be successfully done using the transducer on top of skin. However, if this does not produce a clear picture the technician use a special transducer in one of the body's openings.
What are the benefits of ultrasound?
- They are painless and do not require needles or incisions, although the transducer wand can sometimes be uncomfortable.
- There is no use of radiation which makes these tests safer than X-rays, CT scans or an MRI. There are absolutely no harmful side effects.
- Soft tissues don't show it very well in the next day but very clearly in an ultrasound image.
They are easily accessible and cost less and other techniques.
What is expected during ultrasound?
At times the doctor may issue instructions such is not eating or drinking or wearing lotion or perfume before the test. You may need to drink several glasses if your bladder needs to be full. You will also be given a gown for wearing so that the ultrasound technician can easily maneuver the transducer in the area which will be screened.
You will be down on the bed and the ultrasound tech will use a water-based gel so that the transducer can make contact with the skin without allowing for any air between; the measurements, notes, and still images maybe taken during the process.
While an MRI can take up to two hours, an ultrasound can take anywhere from 10 minutes to about one hour. You will be awake and alert for the entire process, and the technician will often be able to show you on the computer what they are seeing.
How much will an ultrasound cost?
There are two things that need to be considered while getting a fair idea as to what the ultrasound cost in Delhi is. The first point is of course the fact that it depends mostly on the part of the body which has to be examined in the ultrasound test. Next, given the fact that India is a diverse country multi-tier facility like super specialty hospitals and nursing homes, the prices vary. Ideally, the cost of ultrasound ranges between INR 500 and 3200.
