Key Indications for MRI Contrast in Neurology
Contrast administration during an MRI is crucial when evaluating potential tumors, infections, inflammation, or demyelination. For instance, in cases of suspected encephalitis, as indicated by symptoms like headache and altered mental status, MRI with contrast can help differentiate between infectious and post-infectious conditions. The importance of contrast is also underscored in instances of acute disseminated encephalomyelitis (ADEM), where inflammation can lead to characteristic changes visible on specific MRI sequences. Overall, these key indications guide clinicians in selecting appropriate imaging strategies to enhance diagnostic accuracy in critical pediatric cases.
