Ultrasound images come from sound waves passing into the body. Those sound waves send echoes back to produce images of the internal structures of the body. The sound waves do not harm the body. Ultrasound can also show internal motion such as blood flowing through the veins and the heart beating. The sound waves are produced from a wand which the technologist moves over the area to be examined.
General ultrasound imaging most effective in locating and measuring structures inside the body using high frequency sound waves. There is no ionizing radiation involved in general ultrasound.
Obstetric ultrasound is the use of ultrasound scans during pregnancy. Since the 1950s, this type of sonography has been the most effective diagnostic tool for conditions among pregnant women and their unborn children. A full bladder is often required for abdominal scans early in pregnancy.
This safe and painless ultrasound produces images of the body’s veins and arteries. Because ultrasound images are captured in real time, they can show the structure and movement of internal organs as well as blood flowing through vessels.
Ultrasound Guided Biopsy
Ultrasound guided biopsy is an extremely precise method for obtaining cells from a suspicious area of the body. During an ultrasound guided biopsy a physician uses a tiny needle, inserted into the body, to retrieve a tissue or fluid specimen from an organ or tumor while being guided by ultrasound images.
