Quick Overview
Artifact Information
NAME
Crosstalk, cross excitation
DESCRIPTION
Anomalous intensities in an image
REASON
HELP
Slice gap minimum 10%
Crosstalk is an artifact introduced into images by interference between adjacent slices of a scan, caused by a slice profile that is not ideal due to the constraints of the measurement technology. If the slice distances are too small, there is cross talk between the slices, which can affect T1 contrast.

Image Guidance
This artifact can be eliminated by limiting the minimum spacing (for the most sequences a minimum gap 10% and for IR sequences 20%) between the slices. Crosstalk can also be reduced by selection of interleaved slices (so a slice gap will not be necessary), but interleaved data acquisition can produce large mean intensity differences between adjacent slices.

Multi Angle Oblique
 
The multi angle oblique technique gives the ability to display anatomical structures in a variety of planes from the data acquired in just one MRI scan. This technique is useful, for example in lumbar spine MRI obtaining images of each intervertebral disc, individually oriented at a different angle, to better recognize herniation or to compare degenerative changes.
This technique is more difficult in the cervical spine MRI region because of the small vertebra and therefore a short distance between the multi angle oblique planes. In case of too short distance or overlapping slices the crosstalk (artifact) destroys the signal with reduced image quality.
