B-Flow is a type of ultrasound imaging that allows visualization of blood flow by selectively enhancing the signal from moving blood cells while simultaneously suppressing tissue signal 1. Unlike color Doppler, it does not show flow direction or amplitude.

B-flow is used clinically to image the anatomy of a blood vessel or the overall vasculature of a region. Similar to color Doppler, it helps select a particular vessel for quatitative spectral Doppler analysis. A B-flow flashlight sign has been described recently, which can aid detection of floating and wall adherent arterial thrombi and emboli.
