    Neurospin

    Wise:

    Do you think that neurospin will help to better identify the recoveries made with therapies already available for individuals suffering from a SCI?

    Al,

    There are several of these types of centers in the United States. They do provide higher resolution images of the spinal cord but the resolution is limited to about 100 micra (bigger than most neurons), even with the strongest magnet, by intrinsic movements of living tissues. Every time a person breathes and the heart beats, the spinal cord moves. The movements will blur the image. The biggest magnets are able to capture images over shorter periods of time but it is still not fast enough. The problem is like taking a picture of a vibrating object in a dark room. If one can put a flash on or reduce the shutter speed, one can capture the moving object more clearly. In the past decade, CT scans have become fast enough to be able to capture images of the heart but MRI is not yet at this point. As you know, obtaining proof of regeneration is difficult, even with light microscopy of spinal cord sections. On the other hand, I am hopeful that some of the new techniques, such as tensor analysis may yield important information about the spinal cord. Tensor analysis is of interest because these images show directional elements and white matter shows up as bright areas compared to gray matter. So, with tensor analysis, it may be possible to quantify the amount of white matter remaining at different levels of the spinal cord. I am hoping to get such technology for our lab at Rutgers.

    So, at the present, I believe that the gold standard for neurological recovery is and should be careful and standardized examinations by well-trained and experienced clinicians.
