- Abstract
Objective To explore the clinical application value of low radiation dose iterative technique in craniocerebral spiral CT three-dimensional imaging. Methods Two hundreds and thirty patients with suspected lesions receiving craniocerebral scanning imaging in the Chenzhou Municipal First People's Hospital from July 2016 to June 2017 were collected and divided into the routine dose group(I)and low radiation dose iterative technique spiral scanning groupII),115 cases in each group. The original image and reconstructed image were transmitted to the GEAW4.2 workstation,and were performed the aftertreatment by three CT doctors. The 4-points scale was adopted to independently evaluate the image quality in the two groups. The t test was used to compare the radiation dose,objective indicators(noise)and subjective scores of image quality between the two groups. Results Compared with the groupI,the radiation dose in the group II was significantly decreased,the difference was statistically significant(P<0.01).The average effective dose in the group II was(0.72±0.16)mSv,the reduction rate reached 63.45%. The reduction rates of CTDIvol and DLP were 84.74% and 63.44% respectively. The image quality had no statistical difference between the groupI and group II(P>0.05). Conclusion Using low radiation dose iterative technique for conducting craniocerebral spiral CT three-dimensional imaging not only ensures the image quality,but also significantly reduces the radiation dose,and has good clinical application value.
