ABSTRACT
Objective To observe value of thin slice CT multiple signs combined with multiplanar reformation(MPR)for diagnosing tracheobronchial tuberculosis(TBTB).Methods Data of 234 TBTB patients who underwent chest thin slice CT scanning were retrospectively analyzed.MPR was performed,the direct signs and indirect signs of TBTB were observed.The diagnostic efficacy of axial plain CT images(direct observation)and of MPR combined with the former(combined observation)were compared.Results The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of direct observation was 38.88%(201/517),98.13%(1 789/1 823),85.53%(201/235),84.99%(1 789/2 105)and 85.04%(1 990/2 340),respectively,of combined observation was 91.10%(471/517),98.85%(1 802/1 823),95.54%(471/493),97.51%(1 802/1 848)and 97.14%(2 273/2 340),respectively.Significant differences of sensitivity,positive predictive value,negative predictive value and accuracy were found(all P<0.001),whereas no significant difference of specificity was found between 2 methods(P>0.05).Conclusion Thin slice CT multiple signs combined with MPR could be used to effectively diagnose TBTB.
