CSF may be gadolinium's route to the brain
By Wayne Forrest
A study published in the August issue of Radiology offers further evidence of a mechanism for gadolinium deposition in the brain after the administration of MRI contrast. Researchers detected gadolinium accumulation in cerebrospinal fluid (CSF) -- even in patients with an undamaged blood-brain barrier and normal renal function.
