Which type of artifact can mimic true pathology in imaging?

Side lobe artifacts can indeed mimic true pathology in imaging. These artifacts occur due to the presence of additional sound beams that radiate away from the main beam in ultrasound, particularly in scanners that use mechanical or phased array transducers. When these side lobes interact with highly reflective structures, they can produce echoes that are displayed on the image as if they originated from a different location, potentially resembling true lesions or other pathological findings. This can lead to misinterpretations by clinicians if not carefully evaluated.

Understanding side lobe artifacts is essential for sonographers as it emphasizes the need for careful examination of any suspicious findings in relation to the patient's clinical history and the imaging context. By recognizing these artifacts and knowing their appearance, sonographers can differentiate them from true pathology, leading to more accurate diagnoses.
