Abstract:
of left and right side cerebral cortical veins was 159.16(154.88-164.13)ppb(× 10-9), 164.61(156.23-168.04) ppb, respectively. The median susceptibility (extent) of left and right side thalamostriate veins was 160.51 (152.14-170.06) ppb, 162.48(153.47-173.66)ppb, respectively. Left were less than the right, and the difference was statistically significant (Z=-3.14,-2.02, P<0.05). And the difference of two side of other cerebral venous susceptibility had no statistical significance. The median susceptibility (extent) of right cerebral cortical veins, left thalamostriate veins and right septal veins of 22 male was 166.22(159.21-169.99) ppb, 168.65(159.19-174.45)ppb and 153.42(148.10-161.78)ppb, respectively. The coresponding positions of median susceptibility (extent) of 38 female was 161.10(155.06-167.15)ppb, 157.70(151.53-164.41)ppb and 147.52(142.94- 154.16)ppb, respectively. The susceptibility of right cerebral cortical vein, left thalamostriate vein, right septal vein of male was significantly different from the females (Z=-2.03,-2.20,-2.33, P<0.05). Futhermore, we also found that there had positive correlation between age and right thalamostriate vein(r=0.28,P<0.05). Conclusion The magnetic sensitive of the right thalamostriate vein tends to increase along with the age, and some of peoples had difference with bilateral and age.
