Color Doppler ultrasound is a medical imaging technique which is used to provide visualization of the bloodflow, using color processing to add color to the image so that a doctor or care provider can clearly see what is happening inside the body. This technique requires the use of an ultrasound machine which is capable of color Doppler ultrasound, and can be performed in a hospital or clinic as an outpatient procedure. Having this imaging study performed is not usually painful, and the patient does not require sedatives.
