Which choice is NOT a true statement regarding this filling defect within the gallbladder?

The filling defect displays a significant amount of attenuation.
It has created a shadowing artifact.
Regions deeper than the filling defect are obscured.
It has created an enhancement artifact.

The correct answer is: It has created an enhancement artifact.

The correct answer is D. It is correct because an enhancement artifact is a term used when an area appears brighter than expected on an ultrasound image. When there is a filling defect within the gallbladder, it typically results in a shadowing artifact, as mentioned in choice B. This artifact occurs due to sound waves being blocked by a structure or abnormality, causing a shadow to appear on the image. Choices A and C are also incorrect as a filling defect within the gallbladder often results in a significant amount of attenuation, affecting the clarity of the deeper regions in the area of interest.
