UltraSound(SonoGraphy)

 The ultrasound is a noninvasive medical exam that uses sound waves to analyze parts of the body. During an ultrasound, a technician will use a device with an attached transducer (a small plastic paddle) to generate sound waves and send these through the body. Then, using either software or by hand, they will manipulate these echoes into images of what is inside your body. An ultrasound allows your practitioner to see internal details, such as blood flow, tissue structure, or fluid levels. This technique is also used to examine the fetus during pregnancy. The use of this technique has grown significantly in recent years due to technological advances in miniaturization and signal processing.

The term ultrasonography is usually reserved for the use of transducers more than 6 cm in length. Other uses of ultrasound are not technically ultrasonography since they do not use transducers more than 6 cm in length even though they are similar. For example, the diagnostic medical ultrasound uses sound waves above about 12 to 30 wavelengths.

Ultrasonic examinations present a multitude of advantages over other diagnostic tests, particularly by providing more information on diagnosis and surgical procedures. In diagnostic applications, ultrasound provides a diagnosis of disease, particularly when vascular abnormalities or structural defects can be visualized. In many cases, this eliminates the need for invasive imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI). As a result, lower radiation doses are used, which reduces the risk of causing cancer.(ultrasound centre in north delhi)

In general, ultrasonography is a very safe radiologic procedure. When a contrast medium is administered to enhance visualization during imaging procedures, there is rarely any adverse effect on the patient.
