SWI
images for 37 age and gender matched healthy paired subjects (Chinese versus
Caucasians) were retrospectively reviewed. the GP was measured in two
adjacent slices. Two cutoffs were used and the percentage cutoff pixels
between two groups was compared. Mineralization increases with age in the GP
whether measured with phase or magnitude. For the right globus pallidus,
healthy Chinese subjects have a higher percentage of mineralization at any
age group while for the left side it tends to grow after age 40. SWI offers
the potential to examine differences in disease that might correlate with
mineralization.
