Which situation can cause color Doppler noise to overwrite an anechoic or hypoechoic area?
Comprehensive and Detailed Explanation From Exact Extract:
When color Doppler gain is set too high, the system amplifies noise signals, leading to random color speckles appearing within anechoic or hypoechoic areas where no true flow exists. This artifact is known as 'color bleeding' or 'color noise.'
According to sonography instrumentation reference:
''Excessive color Doppler gain can cause noise to overwrite areas without flow, resulting in false color signals within fluid-filled or hypoechoic structures.''
Therefore, the correct answer is D: Color gain set too high.
