Fetal Ultrasound

What is fetal ultrasound?

Fetal ultrasound is a test used during pregnancy. It creates an image of the baby in the mother's womb (uterus). It’s a safe way to check the health of an unborn baby. During a fetal ultrasound, the baby’s heart, head, and spine are evaluated, along with other parts of the baby. The test may be done either on the mother’s abdomen (transabdominal) or in the vagina (transvaginal).

There are several types of fetal ultrasound:

  • Standard ultrasound. The test uses sound waves to create two-dimensional images on a computer screen.
  • Doppler ultrasound. This test shows the movement of blood through the umbilical cord, in the baby’s heart, or between the baby and the placenta.
  • 3-D ultrasound. This test shows a lifelike image of an unborn baby.

Ultrasound uses an electronic wand called a transducer to send and receive sound waves. No radiation is used during the procedure. The transducer is moved over the abdomen, and sound waves move through the skin, muscle, bone, and fluids at different speeds. The sound waves bounce off the baby like an echo and return to the transducer. The transducer converts the sound waves into an electronic image on a computer screen.

Why might I need fetal ultrasound?

Fetal ultrasound is a routine part of prenatal care in the U.S. This is because it’s a low risk procedure that gives important information. A routine prenatal ultrasound can check for defects or other problems in the fetus. The following can be examined:

  • Abdomen and stomach
  • Arms, legs, and other body parts
  • Back of the neck
  • Head and brain
  • Heart chambers and valves
  • Kidneys
  • Placenta placement
  • Spine
  • Umbilical cord
  • Urinary bladder

A fetal ultrasound can also show:

Your healthcare provider may have other reasons to request a fetal ultrasound.

What are the risks of fetal ultrasound?

All procedures have some risks. The risks of this procedure include:

  • Mild discomfort from the transducer on the abdomen or in the vagina
  • Reaction to a latex covering for the transducer, if you have a latex allergy

In some cases, an ultrasound may appear to show a problem that is not there called false-positive. The test can also miss a problem that is there called false-negative. In some cases, additional testing may be needed after a fetal ultrasound.

Fetal ultrasound is sometimes offered in nonmedical settings. This is done as a way to give keepsake images or videos for parents. In these cases, it’s possible for untrained staff to misread the images and give parents incorrect information. Make sure to have fetal ultrasound done by trained medical staff. Talk with your healthcare provider if you have questions.

Your risks may vary depending on your general health and other factors. Ask your healthcare provider which risks apply most to you. Discuss any concerns you may have.

Why Ultrasound Technique Is Better Than Others?

Ultra sound is commonly known as sonography. It is a process of reproducing ultrasound images of soft tissues of a particular body part and other organs on the computer screen with the help of the echoes of the sound waves produced by the transducer, a high-frequency generating instrument.
Ultra sound is commonly used during the different stages of pregnancy to denote the foetal health, date of delivery, birth defects etc. However, in recent times, the ultra sound has also been associated with the diagnosis of other body parts such as the eyes, heart, gall bladder, liver, ovary, uterus, kidney, uterus, testicles, and ovaries. Ultra sound has also been useful in conducting biopsies for suspecting cancer patients, although not all of the cancers are detected by this imaging process. 3D & 4D ultrasound imaging are useful for looking at a particular body portion with much more precision and in slow motion respectively.

The advantages of ultra sound are:
1. The process of ultrasound imaging is a painless and a fast one. It does not require any insertion of needles or similar objects to denote the problems of the concerned body part.
2. The process is more convenient as compared to other similar imaging processes like MRI, mammogram and x-rays as they can capture images of the soft tissues, blood flow & cysts more clearly than the other processes.
3. The process is free of any harmful effects as there are no chances of exposure to radiation as compared to similar processes such as CT scans or X-rays. 

In case you have a concern or query you can always consult an expert & get answers to your questions!

Ultrasonic Scaling of Teeth
Sometimes patients are worried whether ultrasonic scaling makes the teeth more mobile. In reality it is just the opposite. During and immediate post scaling patients may find spaces between their teeth but that is because the calculus and other foreign particles have been dislodged to clean the gum area. But very good healthy gum tissues grow back to fill up the spaces making your teeth and gums stronger and better.

Ultrasound - Why It is Important?

We are mortals and changes are bound to happen in the functioning of our body and the organ's of the body with every passing day. How the body reacts to the external environment needs to be constantly studied. Therefore, It is important to keep a check of what's happening within your body and live a healthy life.

The check could be need based as suggested by doctor to diagnose a disease or for a general health! Ultrasound scan is an important diagnostic measure to check the state of the organs inside our body via sound waves. It's is also known as sonogram, diagnostic sonography and ultrasonography. 

Types of Ultrasound
Although all types of ultrasound basically work the same, but there are a few differences in the below listed types of ultrasound. Doctor's conduct the test basis the need.

  1. Doppler Ultrasound 
  2. Obstetric Ultrasound 
  3. 3D and 4D Ultrasound
  4. Echocardiograms Carotid Ultrasound

How does it work and why it is done?
It uses high frequency sound waves to create an image of some part of the inside of the body, such as heart and blood vessels, liver, gallbladder, spleen, pancreas, kidneys, bladder, uterus, ovaries, eyes, thyroid, and testicles.

  1. View the uterus and ovaries of a pregnant woman and assess her foetus
  2. Diagnose gallbladder disease
  3. Evaluate flow in blood vessels
  4. Assess abdominal pain or other concerns
  5. Guides a surgeon on a needle biopsy and treatment of a tumor
  6. Kidney Stones
  7. Pelvic ultrasound for ovarian cysts, uterine fibroids, uterine growth and endometriosis
  8. The thyroid gland can be imaged using ultrasound looking for nodules, growths, or tumors
  9. Detect bulging of fluid from a swollen knee joint
  10. Veins evaluation to assess whether swelling in a leg is due to a blood clot, deep vein thrombosis or another cause

Why Ultrasound is preferred over other methods 

  1. Generally painless and does not require needles, injections or incisions.
  2. Patients aren't exposed to ionizing radiation, making the procedure safer than diagnostic techniques, such as X-rays and CT scans. In fact, there are no known harmful effects when used as directed by your healthcare provider.
  3. Ultrasound captures images of soft tissues that don't show up well on X-rays.
  4. Ultrasound is widely accessible and less expensive than other methods.

It has some limitations, such as the sound waves do not transmit well through dense bones or parts of the body that may hold air or gas, such as the bowel and thus has a diagnostic limitation.

From cancer prevention to prenatal diagnostics: ultrasound examination (sonography) is a painless method for examining the internal organs. This involves displaying images of the body's structures using ultrasound waves.

We offer the following ultrasound examinations:

  • Whole abdomen (liver, gall bladder, kidneys, pancreas, urinary bladder, prostate, uterus, ovary etc can be clearly visualised on ultrasound)
  • Obstetric (whereby the number, position, development of foetus and its environment etc can be noted. Congenital anomalies may be diagnosed)
  • Transvaginal scans
  • Transrectal scans
  • Ovulation studies

How to prepare for an ultrasound

  • For scans of the liver, gall bladder and pancreas (upper abdomen) overnight fasting is required
  • For pregnancy up to 3 months and for scans of the uterus, ovaries, kidneys, urinary bladder and prostate, please do not pass urine for 2-3 hours and drink 3-4 glasses of liquids 1 hour before the scan
  • For all other scans, no preparation is required

Ultrasonic Lipolysis: Reduce Weight By The Help Of It

Ultrasonic Lipolysis: Reduce Weight By The Help Of It

Is there anybody who is happy with their body? Definitely not! Almost everyone wants to lose weight. While some want to reduce their overall weight, others are concerned about their thighs, arms, buttocks, and/or belly and get rid of the fat accumulated in these areas. The last couple of decades have seen a drastic change in the lifestyle of people.

With more processed and refined items finding their way into each of our meals and physical activity drastically declining, the new epidemic is obesity. No germs causing it, but our foods. Extensive research is being done to identify newer methods to manage obesity. The complicating issue is also that once lost, the chance of fat re-accumulation always exists. One such new technique is the ultrasonic lipolysis. This technique involves the use of ultrasound waves to kill the fat cells (lipo - fat, lysis - kill). This is a noninvasive method wherein localized fat deposits are reduced, especially in areas like the abdomen, hips, thighs, upper arm, and buttocks. This is an advanced technique available to patients who want to achieve weight loss 
and body contouring.

How it works: The fat that is consumed through foods is digested but then accumulates under the skin. The accumulated fat is seen as fat globules or bubbles. These bubbles are difficult to break but attract more fat bubble formation and therefore fat accumulation continues over a period of time. After a detailed case history and examination, a customized programme is 

drawn that could be of 3 to 5 sessions spread over a period of one to two weeks. 

During each session, heat waves of different wavelengths are applied to the area of fat deposition through fiber-optic lasers. The sound energy gets converted into mechanical energy which helps in bursting of the fat molecules. By a process known as emulsification, the larger fat cells are broken into smaller ones, almost to a liquid form, thereby reducing fat deposits.

Benefits of this include:
1. Non-invasive
2. Painless
3. Improves body contour
4. Reduces body circumference
5. Muscle toning and firming
6. Localized body shaping

Earlier, liposuction was used which would remove the fat leaving sagging skin behind. New research has shown that a combination of lipolysis and liposuction can produce the best results. There is no sagging of the skin in these patients, 
and as an added advantage, there is also skin firming indirectly when lipolysis is done.

Studies have shown that obesity is linked to increased morbidity with higher incidence of cardiovascular disease, stroke, and paralysis. It is therefore, extremely essential that both women and men do all that is possible to reduce weight and fight obesity. If you wish to discuss about any specific problem, you can consult a doctor.

Using An Ultrasound To Assess Penis Health

Using an Ultrasound to Assess Penis Health

Taking steps to maintain good penis health pays off. A healthier penis not only looks better but it is more likely to maintain its function - just as taking care of the body helps it to fulfill its functions more fully. Of course, sometimes even conscientious practitioners of appropriate penis health develop issues that require a doctor's assistance. Assessing exactly what the issue is or what might be causing it may require a doctor to conduct tests or use equipment. And, although this may be a surprise to many men, sometimes a doctor may need to have an ultrasound scan done on a man's penis.

What is an ultrasound?

An ultrasound scan, also known as sonography and typically just called an ultrasound, is a medical test that utilizes high frequency sound waves. These sound waves can provide a doctor with a picture of the inside of the body. The technology is kind of similar to that which is used in sonar and radar in military operations.

Although ultrasound is most often associated in the public mind with pregnancy, where it is used to allow a doctor to get a good look at the fetus and how it is developing, it is often used for other purposes. Basically, if a doctor needs a visual of a person's internal organs (bladder, kidneys, pancreas, thyroid, etc.), he may want to use an ultrasound.

Why ultrasound a penis?

Some men may wonder why a penis might need an ultrasound? Or if the doctor needs a look inside, why doesn't he just use an x-ray?

In terms of an x-ray, that's of limited use when it comes to the penis. X-rays are very good for looking at bones, but the penis doesn't really have bones - so an ultrasound is a better bet.

As to why an ultrasound might be needed, there could be several reasons. A man who is battling erectile dysfunction, for example, might benefit from an ultrasound, as this would enable the doctor to better assess the blood flow in the penis, as well as how that blood flow gets "trapped" for an erection.

An ultrasound may also be useful when a man presents with Peyronie's disease (an excessively curved penis), as a way of determining the location and extent of plaque build-up, or to examine a man suffering from priapism. It can also detect the presence of penile stones or a fracture and pinpoint the presence of unwanted tissue masses.

Is it safe?

Ultrasounds are considered a safe procedure. There is no radiation involved, as opposed to x-rays and some other procedures.

Frequently for a penile ultrasound, an injection will be given to induce an erection. This may in some cases cause pain or light bruising at the site of the injection.

Using an ultrasound to assess penis health can enable a doctor to better pinpoint problems and devise appropriate treatment strategies.

Of course, maintaining excellent penis health requires more than paying a visit to an ultrasound machine. Men can daily support their penis health by applying a first class penis health crème (health professionals recommend Man 1 Man Oil, which is clinically proven mild and safe for skin). There are many crèmes available, so be sure to locate one which contains both L-arginine and L-carnitine. The former is an amino acid which plays role in the creation of nitric oxide. In turn, nitric oxide helps penile blood vessels expand to accommodate increased blood flows. L-carnitine has neuroprotective capabilities, which are valuable for helping maintain an appropriate level of penis sensitivity - something which can easily be lost when the penis is handled too aggressively.
