Whole-brain atrophy in multiple sclerosis measured by automated versus semiautomated MR imaging segmentation

Jitendra Sharma, Michael P Sanfilipo, Ralph H B Benedict, Bianca Weinstock-Guttman, Frederick E Munschauer, Rohit Bakshi
2004 American Journal of Neuroradiology  
Linear measures of atrophy, whole-brain lesion volumes, and clinical data were used to explore validity. The 2D automated method yielded unreliable segmentation and was discarded.  ...  These automated and semiautomated measures of whole-brain atrophy provided similar and nearly interchangeable data regarding MS.  ...  The automated method we tested also has the advantage of separating the brain parenchyma into gray matter and white matter compartments, allowing a compartmental analysis of gray versus white matter atrophy  ...
