Ultrasound, also known as ultrasonography, is a medical imaging technique that uses high-frequency sound waves to produce real-time images of the internal structures of the body. It is a non-invasive and safe diagnostic tool commonly used in various medical specialties, including obstetrics, gynecology, cardiology, radiology, and more.

During an ultrasound examination, a handheld device called a transducer is placed on the skin over the area of interest. The transducer emits high-frequency sound waves into the body, and these waves bounce back (echo) when they encounter different tissues and organs. The echoes are then captured by the transducer and converted into visual images on a monitor.

Ultrasound can provide valuable information about the size, shape, and texture of organs and tissues. It is often used to:

• Monitor pregnancy and assess the development of the fetus (obstetric ultrasound).
  (Determining the sex of the fetus through ultrasound is illegal and strictly prohibited at Sir Ganga Ram Hospital. We adhere to all applicable laws and regulations governing the use of ultrasound technology, and our dedicated medical professionals are committed to upholding ethical practices in patient care.)
• Evaluate abdominal organs such as the liver, gallbladder, kidneys, and pancreas.
• Examine the heart and its structures (echocardiography).
• Diagnose and monitor conditions in the pelvic region, including the uterus and ovaries (gynecologic ultrasound).
• Detect and guide the biopsy of tumors or abnormal growths.
• Evaluate blood flow and vascular conditions (Doppler ultrasound).
• Assess the thyroid gland, breasts, and other superficial structures.
• Guide certain medical procedures, such as the placement of catheters or drainage tubes.

Ultrasound is widely used because it is non-ionizing (does not use radiation) and generally does not cause any discomfort or side effects. It is particularly valuable during pregnancy for monitoring the health and development of the baby without posing any risk to the fetus.

In addition to its diagnostic applications, ultrasound can be used therapeutically for procedures like targeted ultrasound ablation to treat certain conditions.

Ultrasound is a versatile and valuable tool in modern medicine, providing detailed images that aid in the diagnosis, treatment, and monitoring of various medical conditions.
