To investigate the clinical value of low-dose CT diagnosing head trauma,providing a reference for clinical diagnosis.
Methods
48 patients with head trauma were selected,routine CT dose was applied in the initial diagnosis,then 70%,50%,30%(compared to routine CT dose)CT dose were applied in review diagnosis.Image results and radiation dose were compared in different doses.
Results
With the scanning dose reduction,excellent rate of image decreased roughly,but rates of four doses were similar to each other,there was not significant statistical difference(P> 0.05);during routine scanning,the radiation level was up to 96.59m Gy,with scan dose reduction,radiation levels were significantly lower,compared with routine radiation level,low-dose radiation level had significant statistical difference respecttively(t= 4.293,P<0.05;t= 7.547,P< 0.01;t= 9.438,P< 0.01).
Conclusion
In CT diagnosis for head trauma,low-dose CT checkups are credible with small dose radiation,which can be a priority diagnosis option.
