Abstract：Objective To explore the value of low‐dose multislice CT in the reexamination of cerebral hemorrhage and cerebral infarction .Methods 150 patients with brain infarction or cerebral hemorrhage were subjected to CT scan at dif‐ferent conditions .At first visit ,CT was performed with routine dose scan (130 kV and 130 mAs ,group A) .As for reex‐amination ,CT was performed wiht low‐dose scan conditions (110 kV and 150 mAs ,group B;110 kV and 100 mAs , group C) .The acceptance rate and noise value of scanning images in three groups were evaluated by double blind method and ,then ,image quality was compared .Results The CTDIvol value of group B and group C was 24 mGy and 16 mGy re‐spectively ,which decreased by 58% and 72% compared with that of group A (56 .7 mGy) ,with statistically significant differences .The average value of image noise of group B and group C was slightly higher than that of group A ,but ,with‐out statistically significant difference ( P >0 .05) .Conclusion Low‐dose multislice CT can not only significantly reduce the radiation dose in the reexamination of cerebral hemorrhage and cerebral infarction ,but gain the satisfactory image for the diagnosis as well .
