CT measurements on subarachnoid cistern of Zhuang nationality

Objective To obtain the CT anatomical data and its variety regulation of Subarachnoid cistern of Zhuang nationality in Guangxi Methods Choose the head CT photography (127 males,127 females) Six items were weasured, and the data were analyzed. Results The size of subarachnoid cistern in the males was larger than those of the females, and the sex difference was significantly obvious The data comparison between each two age groups showed the cistern longitudinal fissure cerebri and supracellar cisterns of age 60 has significant differences (P<0 05; supracellar cisterns of age 50 was excepted), cisternae ambiens of age groups showed difference (P<0 05) but the close together age(P>0 05) Significant difference in quadrigeminal cistern was showed between age 20～ and other age groups, and between age 30～and age 60～as well No significant difference was showed between the cisterns of lateral fossa of cerebrum among the three age groups before age 50 Conclusion The age variety of subarachnoid cistern of Zhuang have its own charcteristics and regulation The CT anatomical data of the subarachnoid cistern of the Zhuangs in the males were lager than that of females, and the sex difference were significantly obvious
