Abstract:
Objective:To evaluate the clinical value of 16-slice spiral CT low dose chest scanning in the diagnosis of pulmonary tuberculosis.
Methods:From June 13, 2014 to June 20, 2017, 80 patients with pulmonary tuberculosis in Yuyao People's Hospital were selected in the study.The conventional chest dose(control group) and low dose(observation group) of 16-slice spiral CT were used.The diagnostic accuracy, radiation dose of the two methods, lymph node or vascular space display and image features were observed.
Results:The diagnostic accuracy of the two methods had no statistically significant difference (P>0.05). The dose product length, the CT dose index in the observation group were (32.98±2.57) mGycm, (44.29±3.47), respectively, which were significantly lower than those in the control group[(127.66±5.03)mGycm, (44.29±3.47)](t=106.01, 21.05, all P<0.05). The display clarity of lymph nodes or vascular space of the observation group was 90.00%, which of the control group was 92.50%, there was no statistically significant difference between the two groups (P>0.05). The rates of ground glass shadow, burr of the observation group were 29.32%, 31.58%, respectively, which were significantly lower than those of the control group(41.35%, 47.37%), the differences were statistically significant (χ2=4.21, 6.94, all P<0.05). Other signs detection probability are similar between the two groups and had no statistically significant differences (all P>0.05).
Conclusion:The low dose chest CT scan with 16 rows spiral CT has high clinical value, low radiation dose and high diagnostic accuracy in the diagnosis of pulmonary tuberculosis.
