![]() It can also be used to check the abdomen for conditions such as: Why might I need an abdominal ultrasound?Ībdominal ultrasound may be used to assess the size and location of abdominal organs and structures. Other related procedures that may be performed to evaluate the abdomen include abdominal X-rays, computed tomography (CT scan) of the abdomen, and abdominal angiogram. Ultrasound may be safely used during pregnancy or in the presence of allergies to contrast dye, because no radiation or contrast dyes are used. ![]() ![]() Unlike a standard ultrasound, some sound waves during the Doppler exam are audible. The speed at which the sound waves are returned to the transducer, as well as how much of the sound wave returns, is translated by the transducer as different types of tissue.Īn ultrasound gel is placed on the transducer and the skin to allow for smooth movement of the transducer over the skin and to eliminate air between the skin and the transducer for the best sound conduction.Īnother type of ultrasound is Doppler ultrasound, sometimes called a duplex study, used to show the speed and direction of blood flow within the abdomen. The sound waves travel at different speeds depending on the type of tissue encountered - fastest through bone tissue and slowest through air. ![]() The transducer processes the reflected waves, which are then converted by a computer into an image of the organs or tissues being examined. The sound waves bounce off the organs like an echo and return to the transducer. The ultrasound transducer is placed on the skin, and the ultrasound waves move through the body to the organs and structures within. Ultrasound uses a transducer that sends out ultrasound waves at a frequency too high to be heard. Ultrasound may also be used to assess blood flow to abdominal organs. Ultrasound technology allows quick visualization of the abdominal organs and structures from outside the body. This includes the liver, gallbladder, pancreas, bile ducts, spleen, and abdominal aorta. An abdominal ultrasound is a noninvasive procedure used to assess the organs and structures within the abdomen.
