What is an Ultrasound Scan?
Ultrasound scan, also known as sonography, is a diagnostic test that uses high frequency sound waves to create an image of internal organs of the body such as kidneys, heart, liver and joints. It is a non-invasive medical test that helps doctors to diagnose the disease and treat medical conditions.
Ultrasound scanning does not use ionizing radiation (as used in x-rays) and hence there is no radiation exposure to the patient. It is safe and painless procedure with no side effects.

Purpose of Ultrasound Scan
Ultrasound imaging can help diagnose various medical conditions and assess organ damage due to illness. It is also used for guiding purpose during invasive procedures like biopsies.
Doctors generally advise ultrasound to evaluate following symptoms:
Ultrasound has its uses in various areas of medical science:
Ultrasound used to diagnose in emergency: Damage to internal organs can be assessed through ultrasound in emergencies. It can help detect fluid build-up near heart and blood in peritoneal cavities.
Gastroenterology: Ultrasound is used to detect appendicitis which is an inflammation of appendix in abdominal cavity. If detected, a surgery to remove appendix is advised. It is also used to see the images of other solid organs of abdomen like kidneys, liver, pancreas, spleen, bile ducts and inferior vena cava for any abnormalities.
Obstetric Sciences: Ultrasound is used to create image of fetus or embryo in uterus. Obstetric sonography is a standard prenatal procedure. It is used to assess the progress of the pregnancy.
Urology: Ultrasound is used in urology also. Sometimes urine is left in the bladder after a person has urinated. People who cannot empty their bladder suffer from petty bladder muscular tone, or from other conditions that restrict the flow of urine, like bladder stones or enlarged prostate. In such cases, an ultrasound is done to check how much urine remains in patient’s bladder after urinating and hence diagnose the cause.
Organs in pelvic region like uterus can be checked. Pelvic sonography can be done internally or externally. In females, sonogram may be inserted trans vaginally and in males it is inserted through the rectum. It can help the doctor determine the reason for incontinence or obstructed defecation.
Musculoskeletal Sonography: Ultrasound can be used to examine ligaments, soft issues, nerves, muscles bone surfaces and tendons. It is carried out to diagnose sprains, tears, strains and the conditions of other soft tissue.
Neonatology: Ultrasound can be done in newborn infants to check for abnormalities in brain and other body parts.
Cardiology: Ultrasound is widely used in cardiology. An echocardiogram (ECG), also known as cardiac ultrasound, takes two-dimensional or three-dimensional images of heart. It is used to assess the speed of blood flow, the function and condition of cardiac valve areas, dis-functioning of left and right side of heart and leaking of blood from the valves. The overall working of heart can be assessed through echocardiogram. Sonography of arteries can also be done to detect blockages of arteries as well as diagnosing Deep Vein Thrombosis (DVT).
Ultrasound for Treatment: Apart from diagnosis ultrasound is sometimes used to treat some illnesses.
- Ultrasound can be used by dentists to clean the teeth.
- Low intensity ultrasound can stimulate bone growth.
- Ultrasound shock waves are used to break up stones in the kidney, ureter or bladder. The tiny pieces of stones are passed out of the body in urine.
- Cataracts can be treated through ultrasound waves.
- High intensity focused ultrasound can be used to generate heat to treat tumours and cysts.
The Science Behind Ultrasound
Ultrasound imaging is done on the basis of principle of reflection of ultrasonic waves. When a sound wave strikes an object, it bounces back. By measuring this echoed waves, it is possible to determine the object size, shape and consistency.
In medical science, ultrasound is used to assess the changes in appearance, size and fluidity of organs, tissues and blood vessels or to detect abnormal masses called as tumours.
In an ultrasound procedure, a small transducer (probe) and ultrasound gel is applied directly on the skin. High-frequency waves are transmitted from the transducer through the gel into the body. As the sound waves bounce off the organs, tissues and fluids, the sensitive microphone in the transducer records changes in sound pitch and direction. This data is sent to the computer which creates real-time images and displays it on the monitor. One or two frames of the moving picture are captured as still image and are saved as scan reports.
Preparing for the Procedure
If you are advised an ultrasound scan by your doctor, book an appointment without delay as illnesses caught earlier are cured faster.
Procedure preparation will depend on the type of the scan. For some scans your doctor may instruct you not to eat or drink as long as 12 hours before the appointment. For others you may be asked to drink as many glasses of water in two hours before the scan and avoid urinating in order to keep your bladder full.
Wear loose-fitting clothes for your ultrasound scan.
How is the Procedure Performed?
Usually in ultrasound procedure, you will be asked to lie face up on the examination table. you may also be asked to turn to either side for better quality images. After you lay down, a water based gel will be applied by your sonographer to the area to be examined. The gel helps the transducer make secure contact with your sin and eliminate air bubbles. The transducer is than placed on the body and moved back and forth until the desired image is captured.
You might feel a little pain from the transducer moving on a tender area, otherwise the procedure causes no discomfort. On completion of the imaging, the gel is wiped off your sin. The gel does not stain your clothing.
You may be asked to dress and wait while the report is reviewed and printed. You may get your reports then and there only and then you can resume your normal activities.
Types of Ultrasound Scan
Ultrasound scan may be broadly classified into four types depending upon the type of ultrasound image. The choice of Ultrasound scan depends upon the requirement of the investigation and availability of the equipment.
This is the most common type of ultrasound, which creates a series of flat 2-dimensional cross-section image of the tissue being scanned. The images from a 2D ultrasound are black and white and have the same kind of detail as a photographic negative. Doctors use 2D ultrasound regularly throughout pregnancy to check the fetus, assess amniotic fluid and look for birth defects.
3D ultrasound is achieved by scanning tissue cross sections at different angles and reconstructing of the data received into a three-dimensional images. A common use for 3D ultrasound pictures is to closely examine for suspected fetal anomalies. Other more subtle features such as low-set ears, cleft lip, deformation of face or clubbing of feet can be better assessed, resulting in more effective diagnosis of chromosomal abnormalities.
Recently, 4-D or dynamic 3-D scanners are in the market. By updating 3D ultrasound images in quick succession, 4d ultrasound pictures are created. Due to addition of time as fourth dimension, the picture looks more realistic. To be able to look at the face and movement of unborn baby excites the parent and hence creates a parent – baby bond, although health advisors cautions against using scans for such purposes.
A Doppler ultrasound emits high frequency sound waves to see how the blood flows through a blood vessel, usually the ones that supply blood to arms and legs.
A Doppler ultrasound may be used to diagnose following conditions:
- Blood clots
- Heart valve defects or congenital heart disease
- Bulging or narrowing of arteries
- A blocked artery
- Decreased blood circulation in legs
Doppler ultrasound may be done as an alternative to invasive procedure such as arteriography or venography, which involve injecting dye into the blood vessels.
There are three Types of Doppler Ultrasound:
Color Doppler – Uses a wide choice of color to visualize the blood flow measurement. It provides a pronounced representation of blood flow speed and direction as compared to normal Doppler scan.
Power Doppler – It provides more detailed representation of blood flow than the regular color doppler. It can sometime achieve images not accessible by color Doppler, however color Doppler cannot indicate the direction of the blood flow.
Spectral-Doppler– can determine both the direction and amount of blood flow but represent it in graphical form instead of gray scale or colored images.

Benefits of Ultrasound Scan
The ultrasound scan has its long list of benefits
- Most ultrasounds are non-invasive. No poking of needles.
- Is a painless procedure.
- Is totally safe and not use any ionising radiation. It is a preferred imaging modality for pregnant ladies and infants.
- Is easily available and less expensive than other imaging procedures
- It gives a clear picture of soft tissue which X-rays are unable to show up.
- It provides real-time imaging and hence is used to guide minimally invasive procedures lie needle biopsies and fluid aspiration.
Limitations of Ultrasound Procedure
Ultrasound has difficulty penetrating bones and, therefore shows up only outer surface of bone structures and not what lies within. To examine internal structure of bones and joints MRI is typically used.
Obese patients are difficult to examine through ultrasound as the large amount of tissue weakens the sound waves.
Ultrasound cannot be used to study any part of the body containing air, so it is not useful tool for diagnosing lung problems and those of digestive tract. In such cases, barium extracts, CT scanning (check here to know more about CT Scan in India), and MRI (Check here to know more about MRI in India) are preferable.
