Diagnostic ultrasound is generally regarded as safe and does not produce ionizing radiation like that produced by x-rays. Still, ultrasound is capable of producing some biological effects in the body under specific settings and conditions.
What is medical ultrasound?
Medical ultrasound falls into two distinct categories: diagnostic and therapeutic. Diagnostic ultrasound is a non-invasive diagnostic technique used to image inside the body. Ultrasound probes, called transducers, produce sound waves that have frequencies above the threshold of human hearing ...
What is diagnostic ultrasound?
Diagnostic ultrasound is a non-invasive diagnostic technique used to image inside the body. Ultrasound probes, called transducers, produce sound waves that have frequencies above the threshold of human hearing (above 20KHz), but most transducers in current use operate at much higher frequencies (in the megahertz (MHz) range).
How are ultrasound waves produced?
Ultrasound waves are produced by a transducer, which can both emit ultrasound waves, as well as detect the ultrasound echoes reflected back. In most cases, the active elements in ultrasound transducers are made of special ceramic crystal materials called piezoelectrics. These materials are able to produce sound waves when an electric field is ...
How does an ultrasound transducer work?
When used in an ultrasound scanner, the transducer sends out a beam of sound waves into the body. The sound waves are reflected back to the transducer by boundaries between tissues in the path of the beam (e.g. the boundary between fluid and soft tissue or tissue and bone).
Is a diagnostic ultrasound good for bones?
However, it is not good for imaging bones or any tissues that contain air, like the lungs.
Can ultrasound scans show bones?
However, it is not good for imaging bones or any tissues that contain air, like the lungs. Under some conditions, ultrasound can image bones (such as in a fetus or in small babies) or the lungs and lining around the lungs, when they are filled or partially filled with fluid.
Can ultrasound be used for non-medical purposes?
Furthermore, the use of ultrasound solely for non-medical purposes such as obtaining fetal ‘keepsake’ videos has been discouraged. Keepsake images or videos are reasonable if they are produced during a medically-indicated exam, and if no additional exposure is required.
Is ultrasound safe?
Ultrasound imaging has been used for over 20 years and has an excellent safety record. It is based on non-ionizing radiation, so it does not have the same risks as X-rays or other types of imaging systems that use ionizing radiation.
What is ultrasound imaging?
Ultrasound imaging (sonography) uses high-frequency sound waves to view inside the body. Because ultrasound images are captured in real-time, they can also show movement of the body's internal organs as well as blood flowing through the blood vessels. Unlike X-ray imaging, there is no ionizing radiation exposure associated with ultrasound imaging.
What is the FDA's recommendation for medical imaging?
For all medical imaging procedures, the FDA recommends that patients talk to their health care provider to understand the reason for the examination, the medical information that will be obtained, the potential risks, and how the results will be used to manage the medical condition or pregnancy.
Is there radiation in ultrasound?
Unlike X-ray imaging, there is no ionizing radiation exposure associated with ultrasound imaging. In an ultrasound exam, a transducer (probe) is placed directly on the skin or inside a body opening. A thin layer of gel is applied to the skin so that the ultrasound waves are transmitted from the transducer through the gel into the body.
Where is the transducer placed in an ultrasound?
In an ultrasound exam, a transducer (probe) is placed directly on the skin or inside a body opening. A thin layer of gel is applied to the skin so that the ultrasound waves are transmitted from the transducer through the gel into the body. Picture of a transducer (probe) used during an ultrasound exam.
How is ultrasound produced?
The ultrasound image is produced based on the reflection of the waves off of the body structures. The strength (amplitude) of the sound signal and the time it takes for the wave to travel through the body provide the information necessary to produce an image.
What is ultrasound used for?
It is used in obstetrics to monitor the progress of pregnancy, in oncology to visualize tumours and their response to treatment, and , in cardiology, contrast- enhanced studies are used to investigate heart function and physiology.
Is ultrasound harmful?
However, if used imprudently, diagnostic ultrasound is capable of producing harmful effects. The range of clinical applications is becoming wider, the number of patients undergoing ultrasound examinations is increasing and new techniques with higher acoustic output levels are being introduced.
What is the difference between a routine ultrasound and a souvenir ultrasound?
A ‘routine’ obstetric ultrasound scan is conducted with the expectation that it will beneficially inform the management of the pregnancy, whereas a souvenir scan is solely for ‘recreational’ purposes. Thu s, the clinically indicated scan should confer significant benefit, whereas the souvenir scan should not.
Why is ultrasound used in obstetrics?
It is used in obstetrics to monitor the progress of pregnancy, in oncology to visualize tumours and their response to treatment, and, in cardiology, contrast-enhanced studies are used to investigate heart function and physiology. An increasing use of diagnostic ultrasound is to provide the first photograph for baby's album—in the form ...
Is therapeutic ultrasound effective?
The effectiveness of therapeutic ultrasound has not been documented through research. For example, a 2014 study. Trusted Source. on 60 people with knee osteoarthritis concluded that the use of the treatment offered no additional benefit in pain improvement and functions.
What conditions can a physical therapist treat with ultrasound?
It may be recommended if you experience any of the following conditions: carpal tunnel syndrome. shoulder pain, including frozen shoulder. tendonitis. ligament injuries. joint tightness. Physical therapists use therapeutic ultrasound in two different ways:
What is ultrasound used for?
This is diagnostic ultrasound used to capture images of organs and other soft tissues.
Why do physical therapists use ultrasound?
Your physical therapist (PT) might use therapeutic ultrasound to provide deep heating to soft tissue to increase blood circulation to those tissues. This could, theoretically, promote healing and decrease pain.
Can ultrasound be used for heat?
The U.S. Food and Drug Administration has approved the use of therapeutic ultrasound by licensed professionals. It has the potential to produce harm if the heat is left in the same place too long. If, while being treated, you feel discomfort, alert your PT right away.
Can ultrasound cause microplosion?
One potential risk with therapeutic ultrasound is that the rapid pressure changes during cavitation could cause a “microplosion” and damage cellular activity. This is unlikely to occur in most uses of the treatment.
What is therapeutic ultrasound?
Therapeutic ultrasound is a tool in wide use by physical therapists. If it is offered to you as part of your treatment, it should always be part of an overall treatment plan that includes exercise, stretches, or other focused activities.
What is the code for hands free ultrasound?
The appropriate code for hands-free forms of ultrasound is CPT 97039. Phonophoresis is ultrasound treatment that uses a steroidal cream in place of the usual types of conductive gels. Report the ultrasound with CPT 97035 and the steroidal cream with the supply code 99070.
Is pulsed ultrasound nonthermal?
Ultrasound is a constant-attendance modality. Continuous ultrasound clearly provides such a thermal effect, whereas pulsed ultrasound is generally a nonthermal form of ultrasound. Reporting of pulsed ultrasound, however, using CPT 97035 may be inaccurate. Some pulsed ultrasound units, which have ultrasound heads attached to a mechanical arm placed ...
Is CPT 97035 inaccurate?
Reporting of pulsed ultrasound, however, using CPT 97035 may be inaccurate. Some pulsed ultrasound units, which have ultrasound heads attached to a mechanical arm placed over the patient, are marketed as hands-free devices. Constant attendance is not required, and CPT 97035 is therefore inappropria te.
What is the CPT code for phonophoresis?
Phonophoresis is ultrasound treatment that uses a steroidal cream in place of the usual types of conductive gels. Report the ultrasound with CPT 97035 and the steroidal cream with the supply code 99070. Phonophoresis is often misreported as an unlisted procedure (97039).
