Application of MSCT Three-dimensional Digital Navigated Biopsy in Pretracheal Retrocaval Space Lesions / 中国医学影像学杂志

ABSTRACT

Purpose To investigate the application of multi-slice spiral CT three-dimensional digital navigated biopsy technique in pretracheal retrocaval space lesions,and to promote the accuracy and security of the biopsy procedure.Materials and Methods Seventy patients with lesions in the pretracheal retrocaval space were enrolled from January 2013 to December 2015.Study subjects were randomly divided into a control group and a research group.Three-dimensional navigation biopsy was used in the research groups,while CT cross-sectional images guided conventional puncture biopsy was used in the control group.One-time success rate of puncture,complications,diagnosis accuracy and operation time were compared between the two groups.Results Once puncture success rates and definite diagnosis rate of the research group were higher than those of the control group,(Z=-2.150,P＜0.05).The incidence of complications and operation time in the research group were (4/35) 11.43％,and those of control group were 37.14％ (13/35).There was statistic difference (x2=6.293,P＜0.01).Conclusion MSCT three-dimensional digital navigated biopsy technique could improve the one-time success rate of puncture and diagnosis accuracy with less complications and shortened operating time.It is a precise and safe procedure for the diagnosis of pretracheal retrocaval space lesions.
