Abstract:
0.05).(3)The average CTDIvol values were 60?5 mGy,88?10 mGy for 2C_2 and NC_2(C_2)groups,respectively.The corresponding ED values were(12.3?1.0)and(18.0?2.0)mSv,respectively.The CTDIvol and ED values for 2C_2 group were about 32% lower than those of NC_2 group and were statistically significant with P
