Question 27/99

During a color Doppler scan, which angle to flow would most likely result in no color being visualized?

A. 3 degrees

B. 45 degreesC 88 degrees

C. 175 degrees

Correct Answer: C

* Color Doppler imaging is most effective when the angle between the ultrasound beam and the flow of blood is small.
* At an angle of 88 degrees, the flow of blood is nearly perpendicular to the ultrasound beam.
* When the angle is close to 90 degrees, the Doppler shift (frequency change) approaches zero, resulting in little to no color being visualized on the Doppler image.
* Thus, to obtain a color signal, the angle should be optimized to be as close to 0 degrees as possible, with 60 degrees being the practical limit for accurate Doppler measurements.References:
* ARDMS Sonography Principles and Instrumentation guidelines on Doppler angle and its effect on Doppler imaging.
