  • Abstract
  • Look Inside

MR angiograms from 200 neurologically normal subjects aged 30 to 79 years were analyzed to assess the influence of aging and hypertension on the degree of the visualization of the cerebral arteries. The de-gree of MR visualization of the cerebral arteries, in-cluding the IC, M1, and distal MCA, was evaluated on a 4-degree scale. IC and M1 differ in appearance.The MR gradings of each cerebral arteries showed a significant (p<0.001) negative correlation with age.Hypertension, which is a risk factors for arteriosclero-sis, significantly reduced MR grade.
