Sonography is an advanced non-invasive imaging technique that uses the reflection of high frequency sound waves to view the organs and tissues of the human body. In addition to conventional sonography, there is also the so-called Doppler ultrasound, which uses the Doppler phenomenon to get information about the speed of tissue movement, especially blood. It is used to view blood flow and visibility of the vascular wall.
Radiology is a medical speciality that employs the use of ionizing radiation to diagnoze and treat patients. Gradually, other diagnostical methods have been incorporated into radiology which do not use ionizing radiation. Medical ultrasonography is a diagnostic imaging technique based on recording sound waves reflected from body tissues.
Ultrasound examinations help doctors diagnose and suggest further treatment of the patient.
