Abstract
Objective: The aim of this study is compare multislice CT VB and FOB to assess tracheobronchial lesions with multislace CT VB.
Material and Methods: In the period between September 2012 and August 2013 found indications for bronchoscopy and the total of 44 patients underwent FOB and FOB MDCT-SB were included in the study to be evaluated. All patients underwent VB and/or FOB. In both methods, tracheobronchial tree were divided into 18 separate segments. FOB virtual bronchoscopic findings as the gold standard method to assess the results were considered. Accordingly, positive and negative predictive values of MDCT for VB, sensitivity, selectivity and specificity values were calculated.
Results: Patient ages 1 and 79 (mean: 53 ± 16) of the patients ranged from 7 (16%) female and 37 (84%) were men. In FOB 16 narrowing, 9 congestion, four external compression, 11 mucosal abnormalities were found and in the VB 12 narrowing, 16 obstruction, 8 external compression detected. None of the 11 mucosal findings in the FOB could not be determined in VB. Patients detect in FOB 25 cases were detected in VB; two patients with lesions on the FOB, although not detected in the VB (false negative). In 14 cases both FOB and endoluminal lesion was detected in the VB. FOB lesions not seen in the VB lesion in 5 cases (false positive). According to these values, sensitivity 92%, specificity 73%, positive predictive value (PPV) of 82%, negative predictive value (NPV) 87%, Accuracy: 84%, respectively.
Conclusion: Both mucosal biopsies should not be made to give details because of disadvantages such as virtual bronchoscopy fob is not an alternative for the moment. However tracheobronchial tumor research, interventional bronchoscopic procedures and biopsy guidance, foreign body aspiration of the initial assessment, tracheal injury is evaluation and treatment planning, obstructive lesions of the distal show, stenosis evaluation of endobronchial abnormalities characterization and postoperative follow-up issues of virtual bronchoscopy, constantly evolving detector technology and software when placed through the right indications for routine use will take time, we believe that the rightful place.
