Sections:
Truncation artifact in CT is an apparently increased curvilinear band of attenuation along the edge of the image.
This artifact is encountered when parts of the imaged body part remain outside the field of view (e.g. due to patient body habitus), which results in inaccurate measurement of attenuation along the edge of the image. The artifact can be reduced - if possible - by using an extended FOV reconstruction of the affected region 1.
