Purpose
Magnetic Resonance
Imaging (MRI) is an advanced form of X-ray that uses magnetism to create
pictures with excellent anatomical resolution. MRI is especially useful
when studying the brain and nervous system.
One type of MRI is
done after a drug called gadolinium is injected into the vein. Gadolinium
does not usually crossover from the bloodstream into the brain. However,
when it does cross it can be seen by MRI. Therefore, when gadolinium is
detected by MRI it means there has been some disruption of the barrier
that normally exists between the blood and the brain. Researchers believe
that a change in the blood-brain barrier is the first step in the development
of new MS lesions.
The overall goals
of the study are to identify immunological processes that may contribute
to the development of Multiple Sclerosis and to design specific therapies
for the disease.

Official Title:
Evaluation of Progression
in Multiple Sclerosis by Magnetic Resonance Imaging (MRI)
Further Study
Details:
Efforts to measure
progression of disease activity in multiple sclerosis (MS) have been difficult
and this problem has become increasingly evident in the assessment of clinical
changes in patients involved in clinical trials. Recent evidence has suggested
that MRI, and particularly MRI following the administration of gadolinium
to demonstrate changes in blood-brain barrier, may be an effective means
for monitoring disease activity. This study will examine the use of MRI
to evaluate disease activity in MS over time. MRI findings will be correlated
with clinical status. A small number of patients will also be studied by
magnetization transfer (MT) along with MRI in an effort to identify the
metabolic changes occurring in acute lesions of MS. The effect of interferon
beta-Ib, now approved for use in patients with relapsing-remitting MS,
will be studied for its effect on disease activity as measured by MRI.
Immunological studies will be done in parallel with the MRI evaluation.
