An ultrasound scan can identify masses such as breast cancer, fibroid, kidney stones, causes of uterine bleeding, or the sex and health condition of a fetus. There are different types of ultrasound scans are external, internal, and endoscopic, depending on the part of the body to examine. Placing the transducer on the skin and moving it over the body part that is to be examined is the external ultrasound. A gel is applied to the skin to facilitate smooth movement of the transducer and to ensure that there is continuous contact between the transducer sensor and the skin. The common uses of an external ultrasound scan are the examination of the developing fetus in the pregnant mother’s uterus, the reproductive organs, heart, liver, gallbladder, and kidneys. Putting an ultrasound probe into the vagina or rectum is the internal ultrasound; the process commonly known as the trans-vaginal probe, which enables better visualization of the uterus even if the bladder is empty.
Ultrasound can also act as a therapy and may use to treat certain conditions. For example, ultrasound waves may help to relieve pain, calm inflammation and encourage healing in tissues. The ultrasound probe is used for the generation and receiving of sound waves of high frequency which cannot be detected by the human ear. During each ultrasound scan, many sound waves are produced. Ultrasound considered safe and produces no side effects compared with other diagnostic tools. It does not expose patients to ionizing radiation and is therefore safer than CT scans and X-rays. In most cases, ultrasound is not invasive or significantly uncomfortable. It allows for safer procedures involving a needle, catheter or other invasive devices by providing physicians with a real-time visual aid. It usually involves no needles or injections and never requires an incision. There are even as easily transported mobile equipment, which made ultrasound the comparatively inexpensive and is available in many kinds of healthcare facilities. Many conditions that are hard to diagnose occur in the soft tissues and structures of the body not well depicted on X-rays.
While the trans-rectal ultrasound enables more detailed examination of the prostate gland and can include targeted biopsy of the prostate. There is usually no pain with internal ultrasound, but you can feel discomfort during the ultrasound process.As technology has advanced, new ultrasound methods have emerged, such as 3D and 4D ultrasounds. Although 2D ultrasounds are typically sufficient to diagnose a medical issue or to measure baby sex, development, and health, the new 3D and 4D ultrasounds offer more visibility than regular 2D ultrasounds, which only show a flat image on a screen.The abdominal ultrasound may be use to investigate abdominal pain, nausea, vomiting, abnormal sounds and lumps. Structures to be examined may include the gallbladder, bile ducts, liver, pancreas, spleen, kidneys and large blood vessels. Structures that contain air cannot be examined easily by ultrasound because air prevents the transfer of the sound waves.A 3D ultrasound takes thousands of pictures at once. 3D ultrasound makes a 3D image that is almost as clear as a photograph. Some providers use this kind of ultrasound to make sure your baby’s organs are growing and developing normally.
Accordingly, there has been a resurgence of enthusiasm for ultrasound given its absence of related radiation presentation and demonstrated adequacy as a symptomatic and helpful imaging methodology.Providing a review of the history of ultrasound on how the use of ultrasound is expanding in both diagnosis and treatment of urinary stone disease.At long last, how encouraging uses of ultrasound are forming the fate of kidney stone administration.The bone demineralization, drying out and stasis put at expanded danger of shaping kidney stones and the shading doppler ultrasound twinkling antique which features kidney stones with shading can make stones readily detectable with ultrasound.Butthe results suggest twinkling is caused by microbubbles on the stone surface which could be affected by the elevated levels of carbon dioxide found. The kidney stones and imaged with ultrasound while the anesthetic carrier gas oscillated between oxygen and air contains carbon dioxide and the exposure of twinkling was significantly reduced and recovered when the carrier returned to oxygen. These trends repeated again to exposed the carbon dioxide followed by oxygen and the reduction of twinkling caused by exposure to elevated carbon dioxide may make kidney stone detection with twinkling difficulty.
Most people associate ultrasound with pregnancy, the scan that expectant mothers get to view their unborn children. There are many other uses, however, for ultrasound. Your doctor can order an ultrasound if you have pains, swelling or some other symptoms that require an internal view of your body organs. An ultrasound can provide views on such organs as the bladder, the brains (infants) eyes, gall bladder, kidneys and liver. Also included are views of other organs like ovaries, pancreas, spleen, testicles, uterus, and blood vessels. Ultrasound is also a helpful assistant in guiding the movements of surgeons during certain medical procedures like biopsies.
Under some conditions, ultrasound can produce images of the bones (in small babies or fetus), or the lungs and linings around the lungs. This can be done either when they are filled up or partially filled with fluids. One of the most common uses of ultrasound is during a mother’s pregnancy to monitor the growth and development of the fetus. Ultrasound images are displayed in either 2D, 3D or in 4D (this is 3D in motion).
An important function of ultrasound is elastography, a method of measuring and displaying the relative stiffness of a tissue. This is to differentiate tumors from healthy tissues. This information is displayed either in black and white maps.
The other uses are the interventions in the body. Ultrasound can guide a needle during biopsy to help doctors see the position of the needle while it is being guided to a selected target. It is also used in real-time imaging of the location of the tip of a catheter when inserted to a blood vessel and guided along the length of that vessel.
A diagnostic ultrasound is able to image internal organs of the body in a non-invasive way (no cutting or incisions made). It is not good, however, in imaging bones or any tissues that contain air like the lungs. The transducer emits high-frequency sound waves through the patient’s body. The waves produce an echo when they hit a dense object, like an organ or a bone. The echoes are then reflected back into a computer. These sound waves are too high-pitched for humans to hear. What they do is form a picture that can be interpreted by a doctor. Depending on the area examined, the patient may be asked to change positions so the technician can have better access.
