This includes whether the object is solid or filled with fluid.ĭoctors use ultrasound to detect changes in the appearance of organs, tissues, and vessels and to detect abnormal masses, such as tumors. By measuring these echo waves, it is possible to determine how far away the object is as well as its size, shape, and consistency. When a sound wave strikes an object, it bounces back or echoes. Ultrasound imaging uses the same principles as the sonar that bats, ships, and fishermen use. The doctor will infuse saline into the uterus using a small, lightweight catheter. In these cases, the doctor will cover the device with a sterile sheath and lubricate it. Some ultrasound procedures, such as transvaginal or transrectal exams, require the doctor to insert the transducer into the body. It also considers what type of body structure and/or tissue the sound is traveling through. The computer creates the image based on the loudness (amplitude), pitch (frequency), and time it takes for the ultrasound signal to return to the transducer. The ultrasound image is immediately visible on a video monitor. The gel allows sound waves to travel back and forth between the transducer and the area under examination. The technologist applies a small amount of gel to the area under examination and places the transducer there. The same principles apply to sonar used by boats and submarines. The transducer sends out inaudible, high-frequency sound waves into the body and listens for the returning echoes. Some exams may use different transducers (with different capabilities) during a single exam. The transducer is a small hand-held device that resembles a microphone. Ultrasound machines consist of a computer console, video monitor and an attached transducer. It is a special, minimally invasive ultrasound technique that provides pictures of the inside of the uterus.Ī Doppler ultrasound study may be part of a sonohysterography exam.ĭoppler ultrasound is a special ultrasound technique that evaluates blood as it flows through a blood vessel. Sonohysterography is also known as saline infusion sonography. The images can also show blood flowing through blood vessels. Because ultrasound captures images in real-time, it can show the structure and movement of the body's internal organs. Ultrasound exams do not use radiation ( x-rays). A computer uses those sound waves to create an image. The probe collects the sounds that bounce back. High-frequency sound waves travel from the probe through the gel into the body. It uses a small probe called a transducer and gel placed between the transducer and the body. Ultrasound imaging is also called sonography. It produces pictures of the inside of the body using sound waves. Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. What is Sonohysterography (Ultrasound of the Uterus)? Leave jewelry at home and wear loose, comfortable clothing. Inform your doctor if there's a possibility you are pregnant. Little or no special preparation is required for this procedure. It is best to perform hysterosonography immediately after your period and within 10 days after the first day of your period to minimize the risk of infection and unintended loss of a very early pregnancy. Ultrasound does not use ionizing radiation, has no known harmful effects, and provides a clear picture of soft tissues that don't show up well on x-rays. Using a small tube inserted into the vagina, your doctor will inject a small amount of sterile saline into the cavity of the uterus and study the lining of the uterus using the ultrasound transducer. Your doctor will insert a speculum into your vagina and insert a catheter into the cavity of the uterus. Hysterosonography is performed very much like a gynecologic exam. Hysterosonography, also called sonohysterography, uses sound waves to produce pictures of the inside of the uterus and help diagnose many problems, including unexplained vaginal bleeding, infertility, and repeated miscarriages.
