However, inasmuch as torsion and other sources of testicular pain can consistently be determined by palpation alone, some studies have suggested that the only real benefit of an ultrasound is to assure the patient that he does not have cancer.

" Electric diathermy " ( not to be confused with therapeutic ultrasound ) may be loosely called " diathermy ," but it does not use dielectric heating but rather high frequency alternating electric or magnetic fields, sometimes with no electrode or device contact to the skin, to induce gentle deep tissue heating by induction or dipole rotation.

When Juliet, their doctor does an ultrasound on their baby, they remember moments from the original timeline, and they perfectly speak English and call their baby " Ji Yeon.

It has also been used historically to evaluate for testicular torsion, although ultrasound is more commonly used in current practice, as it does not deliver a radiation dose to the testes.

The research uses ultrasound waves to create acoustic radiation pressure, which provides tactile feedback as users interact with the holographic object.

Some women may interact with the healthcare system by getting an ultrasound to diagnose symptoms if they ’ ve had a mother, sister or grandmother who has previously suffered with these benign tumors.

Ultrasonic hearing can occur if ultrasound is fed directly into the skull bone and reaches the cochlea through bone conduction without passing through the middle ear.

Typically, a concentrated salt solution is injected directly into the fetal heart using ultrasound to guide the needle.

The explanation for this is that the heart rests directly upon the esophagus leaving only millimeters that the ultrasound beam has to travel.

Under ultrasound guidance, thrombin can be injected directly into a pseudoaneurysm, causing it to clot.

Since the 1970s ultrasound scans have allowed measurement of the size of developing embryos directly and so allow for an estimation of gestation age.

Although a similar device named a " pulsed ultrasound flowmeter " was designed by the Dean Franklin group at the University of Washington, Seattle, USA, its sensor had to be directly attached to the blood vessel wall.

Acoustics is the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound and infrasound.

However, in 2004, Maher concluded that " Physical treatments, such as acupuncture, backschool, hydrotherapy, lumbar supports, magnets, TENS, traction, ultrasound, Pilates therapy, Feldenkrais therapy, Alexander technique, and craniosacral therapy are either of unknown value or ineffective and so should not be considered " when treating lower back pain with an evidence-based approach.

Cultured skin and prostate cancer cells showed significant mortality ( compared to nonmalignant cells ) when treated with a combination of quercetin and ultrasound Note that ultrasound also promotes topical absorption by up to 1, 000 times, making the use of topical quercetin and ultrasound wands an interesting proposition.

There is increased sensitivity to radioiodine therapy in thyroids appearing on ultrasound scans as more uniform ( hypoechogenic ), due to densely packed large cells, with 81 % later becoming hypothyroid, compared to just 37 % in those with more normal scan appearances ( normoechogenic ).

Blume announced she was diagnosed with breast cancer in August 2012 after undergoing a routine ultrasound as she was preparing to leave for a five-week trip to Italy.

An ultrasound test can be performed, and together with the exposure dates, a better idea of when the cria is expected can be determined.

How do songbirds learn new songs and bats localize with ultrasound?

Radiological examination of the temporal artery with ultrasound yields a halo sign.

In most cases, the source of atherosclerosis is usually identified with an ultrasound.

Approximate frequency ranges corresponding to ultrasound, with rough guide of some applications

This effect is typically very minor as normal tissue perfusion dissipates most of the heat, but with high intensity, it can also cause small pockets of gas in body fluids or tissues to expand and contract / collapse in a phenomenon called cavitation ; however this is not known to occur at diagnostic power levels used by modern diagnostic ultrasound units.

The ALARA ( As Low As Reasonably Achievable ) principle has been advocated for an ultrasound examination — that is, keeping the scanning time and power settings as low as possible but consistent with diagnostic imaging — and that by that principle non-medical uses, which by definition are not necessary, are actively discouraged.

Many health care professionals consider the risk of leaving these conditions undiagnosed to be much greater than the very small risk, if any, associated with undergoing an ultrasound scan.

Soft tissue imaging of many other parts of the body is conducted with ultrasound.

Ultrasound is also increasingly being used in trauma and first aid cases, with emergency ultrasound becoming a staple of most EMT response teams.

All patients with varicose veins should now be investigated using Duplex doppler ultrasound scanning.

Instead, they noticed tiny dots on the film after developing and realized that the bubbles in the fluid were emitting light with the ultrasound turned on.

Often, fetuses with Turner syndrome can be identified by abnormal ultrasound findings ( i. e., heart defect, kidney abnormality, cystic hygroma, ascites ).

conversely those with mosaic karyotypes are less likely to have associated ultrasound abnormalities.

On occasion, goitre is not clinically detectable, but may be seen only with CT or ultrasound examination of the thyroid.

The newer integrated screen ( formerly called F. A. S. T. E. R for First And Second Trimester Early Results ) can be done at 10 plus weeks to 13 plus weeks with an ultrasound of the fetal neck ( thick skin is bad ) and two chemicals ( analytes ) Papp-a and bhcg ( pregnancy hormone level itself ).

In " stable " angina, chest pain with typical features occurring at predictable levels of exertion, various forms of cardiac stress tests may be used to induce both symptoms and detect changes by way of electrocardiography ( using an ECG ), echocardiography ( using ultrasound of the heart ) or scintigraphy ( using uptake of radionuclide by the heart muscle ).

The chemical effects of ultrasound are concerned with understanding the effect of sonic waves on chemical systems.

The chemical effects of ultrasound do not come from a direct interaction with molecular species.

The calcaneus is the most common skeletal site for quantitative ultrasound assessment because it has a high percentage of trabecular bone that is replaced more often than cortical bone, providing early evidence of metabolic change.

If allowed to view the ultrasound or x-ray monitor, they may be able to see their stones change from a distinct bright point ( or dark spot depending on whether the fluoro unit is set up in native or bones white ) to a fuzzy cloud as the stone is disintegrated into a fine powder.

It was mechanical and used ultrasound to change the channel and volume.

Generally this limits the resolution of ultrasound measures of SV and CO to ± 20 %; better than invasive catheter measures but not as accurate as the USCOM Doppler method which has a proven 5 % sensitivity to change.
