Doppler Study

A Doppler ultrasound is a noninvasive test that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can't show blood flow.

EBUS machine has the facility to evaluate the mediastinal vessels though doppler to rule out clots in pulmonary vessels.
