This is Why Do You Need a Doppler Ultrasound?
A Doppler ultrasound is a noninvasive diagnostic that uses circulating red blood cells to reflect high-frequency sound waves (ultrasound) to assess the blood flow via your blood arteries. Normal ultrasounds employ sound waves to create images, but they are unable to depict blood flow. By monitoring the rate of change in its pitch (frequency), a Doppler ultrasonography can determine how quickly blood flows. A sonographer who is trained in ultrasound imaging applies pressure to your skin using a tiny, hand-held instrument (transducer) roughly the size of a bar of soap across the area of your body being scanned, moving from one area to another as required. You may need a Doppler ultrasound if you have symptoms of reduced blood flow or a heart disease. Symptoms vary depending on the condition causing the problem.
Some common blood flow conditions and symptoms are below:
- Numbness or weakness in your legs
- Painful cramping in your hips or leg muscles when walking or climbing stairs
- Cold feeling in your lower leg or foot
- Change in color and/or shiny skin on your leg
- Shortness of breath
- Swelling in your legs, feet, and/or abdomen
The other name for Doppler Ultrasound is Doppler ultrasonography. The test is most frequently used to examine heart health. It frequently takes place in conjunction with an electrocardiogram, a test that gauges the electrical activity of the heart.
