Objective To explore the application value of segmented seamless scanning combined with data reorganization in improving CT examination of emergency head and face trauma. Methods Sixty patients with emergency head and face CT examination from July 2017 to September 2019 in Hefei Binhu Hospital were collected. According to the different scanning methods, they were divided into improved group and routine group, with 30 cases in each group. In improved group, segmented and seamless scanning was used, while in conventional group, traditional scanning mode was used. The differences in time consumption, head and face DLP,TDLP and TED of the two groups were compared after scanning. Comparison of the difference in image quality was performed in two groups using χ2 tests. Results The mean examination time(89.50±18.56) s, head mean DLP(744.48±0.00) mGy×cm, face mean DLP(192.32±16.52) mGy×cm, mean TDLP(938.73±16.04)mGy×cm, TED(1.97±0.03) mSv in improved group were all lower than those in conventional group (P<0.05). The image quality between the two groups was in accordance with the diagnostic requirements, and the difference was not statistically significant (P>0.05). The three-dimensional display of continuous fracture of the head and face junction showed that the improved group was better than the conventional group, and the improved group could realize the integrated reconstruction of the head and face image. Conclusions The technique of segmented seamless scanning combined with data recombination in CT examination of head and face trauma can shorten the examination time, reduce the radiation dose of head and face, and realize the integrated 3D image of head and face. |
