#DOPPLER ULTRASOUND PREGNANCY PORTABLE#

It is done in an ultrasound room in a hospital or doctor's office. Or it may be done by an ultrasound technologist (sonographer) who works with a radiologist. This test is done by a doctor who is an expert in imaging tests ( radiologist). The test can check for the risk of stroke. The mother has other problems, such as pre-eclampsia or sickle cell disease.Ī transcranial Doppler (TCD) ultrasound may be used in children with sickle cell disease.Blood flow through a blood vessel in the brain can be used to check the health of the fetus. Blood flow through the large blood vessel in the umbilical cord (the umbilical artery) can be looked at. The fetus is smaller than normal for the gestational age.

Doppler ultrasound may be used to guide decisions during pregnancy when: This test can show if the fetus is getting enough oxygen and nutrients. It may check blood flow in the umbilical cord, through the placenta, or in the heart and brain of the fetus. Guide treatment such as laser or radiofrequency ablation of abnormal veins.Plaque in the carotid arteries can reduce blood flow to the brain. Find the presence, amount, and location of arterial plaque.Monitor the flow of blood after blood vessel surgery.

Find out the amount of blood flow to a transplanted kidney or liver.

It also can look at the health of grafts used to bypass blockage in an arm or leg.

Map veins that may be used for blood vessel grafts.

Check for varicose veins or other vein problems.

After a stroke, this can be done with a test called transcranial Doppler (TCD) ultrasound.

Assess blood flow after a stroke or other condition that might be caused by a problem with blood flow.

This is a condition caused by atherosclerosis of the lower limbs.

Check leg pain that may be caused by intermittent claudication.

It's most often used for the neck, arms, and legs.

Find blood clots and blocked or narrowed blood vessels in almost any part of the body.

Power Doppler is most often used to look at blood flow through vessels within solid organs. Power Doppler can get some images that are hard or impossible to get using standard colour Doppler. Power Doppler is a special type of colour Doppler. These colours show the speed and direction of blood flow through the vessel. A computer changes the Doppler sounds into colours that are overlaid on the image of the blood vessel. Colour Doppler uses standard ultrasound methods to make a picture of a blood vessel. This graph helps to show the speed and direction of blood flow through the blood vessel. A computer turns the Doppler sounds into a graph. This test uses standard ultrasound methods to make a picture of a blood vessel and the organs around it.

It uses a portable machine that can quickly check the extent of blood vessel damage or disease. This type of ultrasound can be done at the bedside in the hospital. The doctor listens to the sounds made by the transducer to assess the blood flow through an area that may be blocked or narrowed. This type uses the change in pitch of the sound waves to provide information about blood flow through a blood vessel. The three basic types of Doppler ultrasound are: These graphs or pictures can be saved and reviewed later. Information from the reflected sound waves can be used to make graphs or pictures that show the flow of blood through the blood vessels. If there is no blood flow, the pitch does not change. The movement of blood cells causes a change in the pitch of the reflected sound waves. The sound waves bounce off solid objects, including blood cells. It sends and receives sound waves that are amplified through a microphone.

#DOPPLER ULTRASOUND PREGNANCY SKIN#

During pregnancy, Doppler ultrasound may be used to look at blood flow in an unborn baby to check the baby's health.ĭuring Doppler ultrasound, a hand-held device is passed lightly over the skin above a blood vessel. This problem is called a pulmonary embolism. The test also can find blood clots in leg veins ( deep vein thrombosis, or DVT) that could break loose and block blood flow to the lungs.

It can show blocked or reduced flow of blood through narrow areas in the major arteries of the neck. It helps doctors assess the blood flow through major arteries and veins, such as those of the arms, legs, and neck. A Doppler ultrasound test uses reflected sound waves to see how blood flows through a blood vessel.
