Ultrasound-Exam Description and Information
Ultrasound imaging uses high frequency sound waves to make pictures of the inside of the body. Reflected sound wave echoes are recorded, reconstructed by a computer, and displayed as images on a computer screen. Because ultrasound images are captured in real-time, they can show movement of internal tissues and organs, fetal development, and blood flow. There is no harmful radiation.
Diagnostic (Abdomen, Pelvis, Thyroid, Retroperitoneal)
Ultrasound is a useful way of examining many of the body's internal organs, including the liver, gallbladder, spleen, pancreas, kidneys, bladder, uterus, and ovaries. Because ultrasound provides real-time images, it can also be used to guide procedures such as needle biopsies, in which needles are used to sample cells from organs for laboratory testing.
Some indications for obstetrical ultrasound may be:
- Establish presence of a living embryo/fetus
- Estimate the age of the pregnancy
- Evaluate the position of the fetus
- Evaluate the position of the placenta
- Determine if there are multiple pregnancies
- Diagnose congenital anomalies
Ultrasound imaging of the body's veins and arteries can help the radiologist see and evaluate blockages to blood flow, such as clots in veins and plaque in arteries. Ultrasound of the vascular system also provides a fast, noninvasive means of identifying blockages of blood flow in the neck arteries to the brain that might produce a stroke or mini-stroke.
