What is the effect of ultrasound scan on a person.?!
Question:
Want to know if four ultrasound scans can affect a person and in which ways can this be stop.
Answers:
I routinely preform multiple exams on the same patient. They do believe there are no health risks, if done by a trained and qualified technologist.
There are no health risks associated with ultrasound, although no one knows for sure what the possible long-term effects may be for you or your child. http://www.umm.edu/pregnancy/stayhealthy/articles/ultrasound.html
There is no documented risk. No ionizing radiation exposure is involved. http://health.allrefer.com/health/abdominal-ultrasound-risks.html
Here is some of the problems with a non-qualified person performing ultrasound procedures (Tom Cruise):
Experts say no significant health risks to a baby who has undergone ultrasound at the low levels approved for obstetrics use have been shown. According to the Food and Drug Administration, which must approve ultrasound devices before they are sold in the United States, the only consistent finding has been a slight increase in left-handedness among boys.
But according to the American College of Radiology, which offers guidelines on sonography, laboratory studies have shown that some levels of ultrasound can produce physical effects in tissue, such as vibrations and a rise in temperature, especially when used for a prolonged period of time. http://msnbc.msn.com/id/10309963/

"Similar to other heating modalities, ultrasound affects the properties of skeletal muscle, nerves, enzymes, blood flow, and pain thresholds. Authors agree that frequency and intensity of ultrasound, treatment time, movement speed of the sound head, type of coupling agent, tissue type, and size of treatment area determine the absorption of ultrasound energy in tissues high in collagen. Previous scientific research focused on ultrasound penetration in animal tendons rather than those of a human. It was said that energy absorbed by the tissue was directly related to the size of the treatment area, and that tendons will absorb more than muscle due to its high collagen content. An ultrasound treatment of 2X the effective radiating area (ERA) at a frequency of 3MHz heats muscle at 0.6 degrees Celsius per minute at a depth of 0.8 cm, at 1 W/cm2. My study sets out to determine the magnitude and rate of temperature change in response to ultrasound in human patellar tendon for two different ERA’s. I hope to provide insight to rehabilitation professionals, such as Athletic Trainers, on the safe and appropriate parameter range when performing ultrasound on human patellar tendons using thermal effects. I also wish to open a window to further studies on the use of ultrasound on other human tendons throughout the body."

If you are asking if ultrasound scans can hurt people - the answer is no. Ultrasounds are not like x-rays, where you are being exposed to radiation or something. Ultrasound is just bouncing soundwaves off the part of your body being studied so that the doctor or radiologist can get a picture of what's going on. Ultrasound is also used to treat muscle injury/muscle spasms, etc. It is safe, but is to be used by trained ultrasound technicians only and "read" by specially trained medical professionals.
