A preliminary Radiology. 1992;182:243-6. 7. Duplex scanning in vascular disorders. Strandness Most shunt systems include a valve which regulates drainage.

In consideration of the test results, this new programmable CSF shunt valve is not adversely affected by the 3-T MRI environment and is acceptable for a patient undergoing MRI at 3 T or less when specific guidelines are followed, including verifying the valve setting according to manufacturer recommendations immediately after the MRI procedure.

This can be quite significant, as infection may have further implications and detrimental effects on the individual including abscess formation or shunt occlusion. If infection occurs, the shunt will generally need to be revised (Rinker et al. 2015).
