Wraparound: In the figure on the left, the nose folds into the back of the skull. In the figure onthe right, the ear wraps into the side of the skull.Wrap-aroundMotion: patient motion causes lines to appear in the scan as shown in the following figure.Motion
Metal Artifact: In this example there is a signal void due to the presence of metal near thesubjects head.Metal artifactFolding (see next page): you get this artifact when slices are copied to a T1 based scan (MP-RAGE, SWI or PD) from a T2 based scan (DTI, T2 or fMRI).The things to note there are:1. The folding, this is very clear in the image.2. The shape of the matrix. It should be square when looking in the coronal or sagittalplanes and rectangular on the axial plane. The way to see it in Slicer is by playing withthe image contrast until the background noise is visible.The top figure shows a correct scan, the bottom an incorrect scan.
