Here are the newly revised guidelines
The 2017 newly-revised MRI guidelines for diagnosing and monitoring MS state the following:
- An MRI scan of the brain with gadolinium is recommended for MS diagnosis.
- GBCAs should be used only in instances when they are medically necessary.
- An MRI scan of the spinal cord is recommended if the MRI scan of the brain provides no diagnostic information or if it reveals symptoms are capable of being credited to the spinal cord.
- Patients with relapsing MS should undergo a routine MRI of the brain every 6 months to two years.
- A follow-up MRI scan of the brain is recommended to reassess the original diagnosis, to show dissemination in time for proper diagnosis, to safely monitor disease activity that is silent while on treatment, to assess any sudden clinical worsening, and to provide a new baseline MRI scan before starting or changing treatment.
