The difference in susceptibility of straight sinus among AI patients, non-AI patients and healthy controls.
The susceptibility of straight sinus in non-AI group (256 ± 35) was significantly lower than that in healthy control group (311 ± 43) (P < 0.001, Bonferroni corrected), the susceptibility of straight sinus in AI group (265 ± 61) was significantly lower than that in healthy control group (311 ± 43) (P = 0.004, Bonferroni corrected). But there was no significant difference in susceptibility of straight sinus between non-AI group (256 ± 35) and AI group (265 ± 61) (P = 1.000).
