High-frequency sound waves are used for an ultrasound scan to view inside the body. Because ultrasound scans are captured in real-time, they can also show the movement of internal organs of a body as well as blood flowing through the blood vessels. Unlike X-ray, there is no ionizing radiation exposure associated with an ultrasound scan.
In an ultrasound scan, a transducer is placed directly on the skin. 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.
The ultrasound scan is 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 for a scan.
Benefits of Ultrasound Scan
Ultrasound scanning has been using from 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 scanning systems that use ionizing radiation.
Less Expensive: CT, MRI scan is more expensive than ultrasound, and the expense of diagnostic is a real barrier for some patients
Full Visualization of Gynecological Anatomy: 3D ultrasound provides a view of the coronal plane, which allows for more realistic and complete scanning of internal pelvic organs. Pathology within or around the pelvis is easier to see and understand, especially with other organs and tissue layers, with 3D ultrasound.
Reduced Travel and Wait Times: Ultrasound is accessible and portable for clinicians to have in-house. This eliminates the need for patients to travel to other facilities or make additional appointments, can improve the time to diagnosis for more complex and painful gynecological disorders.
Immediate Results: Ultrasound is live and provides a unique opportunity to view pathology in real-time. Interpretation and evaluation can be conducted immediately after the scan, and a treatment plan can be discussed with the patient during the same appointment.
