High-Resolution CT Using MDCT: Comparison of Degree of Motion Artifact Between Volumetric and Axial Methods

¹ Department of Radiology, Beth Israel Deaconess Medical Center and Harvard Medical School, 330 Brookline Ave., Boston, MA 02215.
² The University of Arizona College of Medicine, Tucson, AZ.

OBJECTIVE. The purpose of this study was to compare the degree of motion artifact on high-resolution CT images obtained using volumetric and axial (nonvolumetric) CT methods.

CONCLUSION. Volumetric high-resolution CT is associated with significantly greater motion artifact compared with axial noncontiguous high-resolution imaging.
