Quix-or anyone else who may be reading medical journals...I just finished reading about a newer criteria being proposed for interpreting MRI results(proposed in 2006) in regards to fulfilling dissemination in space(DIS) requirement for diagnosis following occurance of CIS.
The Swanton require "at least 1 T2 lesion in at least two of four locations defined as characteristic of MS: periventricular, juxtacortical, infratentorial and spinal cord" in order to demonstrate DIS. "Dissemination in time(DIT) was achieved by a new T2 lesion on a follow-upscan irrespective of the timing of a baseline scan."
According to the paper, "initial studies have suggested that these new criteria were more sensitive than previous criteria, without compromising specificity and accuracy." The conclusion is that, compared to Barkhoff-Tintore's criteria(currently used to evaluate MRI images as part of the McDonald diagnostic criteria), "Swanton's criteria are simpler and more sensitive, with a slight decrease in specificity. These results reiforce their use in multiple sclerosis diagnosis."
Anyway, just looking for any thoughts or comments. I am considering presenting this info to my neurologist for his input. It also helps that when this criteria is applied to the three lesions on my brain MRI, I think it qualify me in the DIS category.
If anyone is interested I can provide info regarding the exact article I found.
Thanks and be well!
