What is "artifact" in ultrasound imaging?

Artifact in ultrasound imaging refers to an error that occurs during the imaging process, producing results that do not accurately represent real anatomical structures or pathological conditions. This phenomenon can arise from various sources, such as equipment limitations, patient factors, and imaging techniques. Artifacts can lead to misinterpretation of scans, potentially impacting clinical decision-making. Examples of artifacts include shadowing, enhancement, and reverberation artifacts, all of which can obscure or alter the perception of true anatomical features.

Understanding artifacts is crucial for sonographers as it helps in differentiating between actual findings and those that are false representations caused by the imaging process. This knowledge enables better accuracy in interpreting ultrasound images and ensures effective communication with the rest of the healthcare team.
