Abstract: Ultrasound artifacts are encountered daily in clinical practice and may be a source of confusion on interpretation. Some artifacts arise secondary to improper scanning techniques and may be avoidable. Other artifacts are generated by the physical limitations of the technique. Recognition of artifacts is important, as they may be clues to tissue composition and aid in diagnosis. The ability to recognize and correct potential ultrasound artifacts is important for image-quality improvement and optimal patient care. In this article, we review common ultrasound artifacts that occur in B mode, spectral and color Doppler, and elastography.
Keywords: artifacts, ultrasound, Doppler artifacts, B-mode artifacts
