Sonography Principles & Instrumentation (SPI) Ultrasound Registry Practice Test

Turbulence in blood flow significantly affects ultrasound imaging, particularly by causing artifacts. When blood flow is turbulent, the flow becomes chaotic and unpredictable, leading to varying velocities and directions of the blood cells. This chaotic movement can create inconsistencies in the echo patterns received by the ultrasound transducer.

In ultrasound imaging, artifacts occur when the images do not represent the true anatomy or physiology accurately. Turbulent flow can lead to several types of artifacts, such as spectral broadening in Doppler ultrasound, where the Doppler waveform appears wider due to the range of velocities present in the turbulent flow. This can complicate interpretation and may obscure the detection of specific pathological conditions.

By understanding that turbulence generates these artifacts, sonographers can better interpret images and make more accurate diagnoses. It emphasizes the importance of recognizing how flow dynamics can distort the ultrasound waveforms and images captured, aiding in improved clinical practice and patient care.
