Pelvicsonogram, also known as pelvic ultrasound, involves the use of aprobing object called a transducer and an ultrasound gel that isapplied on the skin. The transducer transmits high-frequency wavesthrough the ultrasound gel, they bounce back, and a computer usesthem to generate an image. The image shows the structure and themovement of the internal organs and the flow of blood in the vessels.There are three types of pelvic ultrasound namely, abdominal,vaginal, and rectal.
Dopplerultrasound is used to perform a pelvic sonogram. It detects movingblood cells and measures their direction and speed by measuring thefrequency of the echoes of the moving structures (Wiley-Blackwell,2014).It is advantageous as it can give a real-time view of the blood flow.In addition, it aids in evaluating major arteries and veins,obstetricsfor fetal monitoring, brain, liver, and kidneys. According toWiley-Blackwell(2014), a doctor may result in the use of Doppler ultrasound to lookthe flow of blood in certain pelvic areas. He or she may also monitorhow fast the blood is moving in the umbilical blood flow therefore,be able to determine whether the fetus is under any stress. This ismostly helpful in determining high-risk pregnancies and offering therequired assistance in delivering the baby. Doppler ultrasound isknown to reduce infant deaths through better timing of caesareansections. Further, Doppler is used to determine the position of thefetus, multiple pregnancies, check for the opening of the cervix, andestablish the age of the pregnancy. Besides, it also reduces cases ofcaesarean sections and induction of labor.
