An ultrasound exam is a safe diagnostic procedure that uses very-high-frequency sound waves to produce an image of many of the internal structures of the body. These sound waves are harmless and may be used with complete safety, even on pregnant women, where X-rays would be inappropriate. Ultrasound is the imaging modality of choice in the field of obstetrics. It is the initial modality used in the assessment of patients with hepatobiliary, pancreatic, and renal or gynaecological symptoms. It is valuable in the detection of fluid collections and abscesses, and can be employed to guide aspiration or drainage procedures.
Doppler
When sound waves are echoed from a moving object, e.g. flowing blood cells, the frequency alters. The frequency shift depends on both the velocity and on the direction of movement in relation to the beam. A focal stenosis in an artery produces a high velocity jet, whereas an occluded vessel produces no Doppler signal.
Doppler is increasingly used to evaluate patients with arterial problems, particularly those with lower limb or carotid disease. Doppler imaging can also be used in the evaluation of the venous system.
