Quick Overview

The slice overlap artifact is another name for crosstalk artifact. If slices of multislice acquisitions are overlapping, the spinning nuclei belonging to more than one slice getting multiple times saturated, which leads to signal loss in this areas.

This problem occurs often in cervical or lumbar spine MRI, when scanning each disc with multi angle oblique technique. If prevention of overlapping is not possible, try to position the saturated region posterior to the spinal canal, outside the region of interest.
