Summary of our results for the various anthropomorphic phantoms and general impressions of the metal artifact reduction methods. √ indicates that the method resulted in a small reduction in streak artifacts, √√ indicates a more substantial reduction in streak artifacts, and ★ indicates that the method was the most successful method of the three investigated and was highly successful for the given site. X indicates that the method is not recommended for use at a particular site.

	Pelvic	Head	Thoracic	Weaknesses/Drawbacks
