Abstract
We present two cases of subcutaneous hematoma in which color Doppler US revealed colored areas under probe compression, and Doppler waveforms obtained from these areas changed rapidly (from a constant flow to a pulsatile flow, and from a high-velocity flow to a slow-velocity flow) according to the degree of probe compression. In our cases, a sufficient number of blood cells within the lesion moving under probe compression was thought to give rise to Doppler signals and changes in Doppler waveforms.
