To my knowledge，however，there have been no reports evaluating age-related changes in cerebral MRA in many neurologically normal subjects. The purpose of this study is to assess the correlation between the visualization of cerebral peripheral arteries in MRA and aging，sex，laterality or lacunar infarctions in magnetic resonance imaging (MRI). Materials and Methods: Two hundred forty four neurologically normal subjects (119 males and 125 females，aged 7 to 82 yrs.) were evaluated with MRA and MRI. A 3DFT-TOF pulse sequence with slab thickness of 115 mm was used to obtain axial，saggital and coronal projection images. The imaging parameters were 30/11/1 (TR/TE/excitations) using a 20 degree flip angle and the voxel size was 0.9x1.1x0.9mm. A total of 6 arteries including bilateral anterior cerebral arteries (ACAs)，middle cerebral arteries (MCAs) and posterior cerebral arteries (PCAs) for every subject were each graded into 8 scores by the degree of visualizaiion of the arteries. Asymptomatic lacunar infarctions were analyzed in subjects of fifties or more. They were scored as 0-2 based on their size and the scores were summed. Results: An age-related decline of visualization of the cerebral arteries was observed in ACA (r=-0.603，p<0.001)， MCA (r=-0.452，p<0.001) and PCA (r=-0.537，p<0.001). Females during the fifth decade had a higher score of visualization of the arteries than males (p<0.01). No substantial relationship was observed between visualization of the arteries and sex in other decades，laterality or lacunar infarctions. Conclusion: The MRA using a 3DFT-TOF pulse sequence with slab thickness of 115 mm disclosed an age-related decline of visualization of thc cerebral arteries and a sex-dependent difference of the visualization in the fifth decade probably due to the decline of the blood flow velocity with aging and a difference in it between females and males in the fifth decade，respectively.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"医歯学総合研究科博士論文(医学) ;
