Description

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. 1. How Ultrasound Works: During an ultrasound exam, a small handheld device called a transducer is used. The transducer emits high-frequency sound waves into the body and then detects the echoes as they bounce back from the internal structures. 2. Obstetric Ultrasound: Obstetric ultrasound is used during pregnancy to monitor the development and well-being of the fetus. It can provide valuable information about the baby's growth, position, anatomy, and detect any potential abnormalities. Obstetric ultrasound is commonly used to determine gestational age, assess the baby's heartbeat, evaluate the placenta and amniotic fluid, and detect multiple pregnancies. 3. Types of Obstetric Ultrasound: a- Transabdominal Ultrasound: In this type of ultrasound, the transducer is placed on the abdomen and moved to obtain images of the uterus, fetus, and surrounding structures. b- Transvaginal Ultrasound: A transducer is inserted into the vagina to obtain more detailed images in early pregnancy or when a closer view is required. 4. Other Uses of Ultrasound: Ultrasound imaging is also utilized in various other medical specialties for diagnostic purposes. It can help visualize and assess different organs such as the liver, kidneys, gallbladder, heart, and blood vessels. Additionally, ultrasound-guided procedures, such as biopsies or fluid drainage, can be performed to aid in diagnosis or treatment. 5. Safety and Non-invasive Nature: Ultrasound is considered a safe imaging technique as it does not use ionizing radiation like X-rays or CT scans. It is non-invasive, meaning it does not involve any incisions or injections, making it generally well-tolerated by patients.
