Abstract
ObjectiveTo explore clinical value of 640 layers volume CT with low dose scanning in adult active pulmonary tuberculosis.
Methods160 cases of adult active pulmonary tuberculosis patients diagnosed by our hospital were selected as the research objects, all patients were conducted routine 640 layers volume CT scanning and then low dose scanning, at the same time conducted thin slice reconstruction of the image of two doses scanning, to observe the imaging features of two kinds of scanning and reconstruction, and assessimage quality, and calculate the CT dose index (CTDIvol), dose length product (DLP) and the effective dose (ED), for qualitative and quantitative evaluation of two doses scanning effects.
ResultsThe quality of scanning image showed no significant significance between the low dose group and the conventional dose group (P>0.05); The quality of thin slice reconstruction image had no obvious statistical significance between the two groups (P>0.05); The scanning imaging characteristics and the thin slice reconstruction imaging characteristics had no significant difference between two groups (all P>0.05). The CTDIvol, DLP and ED in low dose group were significantly lower than that in the conventional dose group (all P<0.01), suggesting the scanning radiation dose of low dose group was decreased obviously.
Conclusions640 layers volume CT with low-dose scanning in the review of adult active secondary pulmonary tuberculosis can obtain the same inspection effect like conventional CT scanning, and can significantly reduce the X-ray radiation dose in CT scanning, make tuberculosis review more security, at the same time reduce the inspection cost, worthy of clinical application.
