Effects of Artifacts on the Diagnosis of Ultrasound Image

In ultrasound imaging, the artifact is the term that can be used to describe various parts of an image that doesnot accurately represent the anatomic structure within the subject being evaluated. The current study aimsto explain the foundation of understanding the artifacts in conventional ultrasound and Doppler techniquesto highlight the effect which may occur as a result of these artifacts. Artifact in ultrasound imaging can beclassified into three categories according to its cause, artifacts caused by the patient, by instrument, and byan operator. Recognition of artifacts is important as they can be considered as tissue composition indicators.Therefore, it helps in the diagnosis. The ability to recognize and correct potential ultrasound artifacts issignificant for image quality improvement and optimal patient care. The most frequent artifact is acousticshadowing that had been seen in 11 from 54 cases and the less frequent is blooming artifact that occurred inonly 1 case from selected cases.
