==Using Color Doppler Ultrasound== | ==Using Color Doppler Ultrasound== | ||
It is sometimes necessary to use color Doppler ultrasound when valvular regurgitation is suspected, although this method should not be used to as the final diagnostic tool to determine valve dysfunction as the Doppler beam is nearly perpendicular to the flow. Instead, the presence of valvular regurgitation is based on the cardiac cycle, not the color-coding.<cite>Feigenbaum1 | It is sometimes necessary to use color Doppler ultrasound when valvular regurgitation is suspected, although this method should not be used to as the final diagnostic tool to determine valve dysfunction as the Doppler beam is nearly perpendicular to the flow.
