Analysis on Transferring Tumor of Skull with High Resolution CT (HRCT)

Objective: As to the transferring tumor of skull, analyze and discuss the relationship about its source, distributing part and oedema around it .Methods: Examine 93 focus of transferring tumor of skull, and scan parallel and increasingly to them. Divide the skull into 3 regions: Region 1 is the boundary of hemisphere skinniness and medulla; Region 2 is hemisphere; Region 3 is cerebellum and the brain stem. Four degrees of oedema: Degree 0 (not dropsy),Degree 1 (ETR<=1),Degree 2 (1=2).Results: transferring focus: 74 ones in Region 1; 14 in Region 2;5 ones in Region 3. Degree of oedema: 16 ones in Degree 0;15ones in Degree 1; 26 ones in Degree 2;36 ones in degree Conclusion: There is no relationship between oedema around transferring tumor and its source and vicious degree; Closely related to the transferring part.
