          Quantitative MRI (qMRI) markers of disease progression 
						such as tissue volume, DTI, and quantitative T1 (qT1) 
						from the brain and cervical spinal cord were assessed 
						for their sensitivity to disease progression in primary 
						progressive multiple sclerosis (PPMS). Thirty-one PPMS 
						patients were assessed twice longitudinally using qMRI 
						and clinical scores. Among the qMRI parameters that 
						showed change at 1 year were qT1 from the upper cervical 
						spinal cord, thalamic and ventricular volumes, FA from 
						the corpus callosum, and MD from caudate. A majority of 
						the qMRI from brain did not show any changes, probably 
						reflecting the pathophysiology of PPMS.
