“…It was the software using curved MPR that allowed us to do so. Although the idea of threedimensional analysis is not entirely new (22,(36)(37)(38), it has not been applied to measuring airway dimensions in patients with COPD. In COPD, the quantitative evaluation of the airways using CT has received less attention than the analysis of emphysema.…”

Rationale: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation caused by emphysema and/or airway narrowing. Computed tomography has been widely used to assess emphysema severity, but less attention has been paid to the assessment of airway disease using computed tomography. Conclusions:We are the first to use three-dimensional computed tomography to demonstrate that airflow limitation in COPD is more closely related to the dimensions of the distal (small) airways than proximal (large) airways.

Tracheobronchial variations in Turkish population

et al. 2008

The tracheobronchial tree exhibits highly individualistic features and many variations. As the anatomic variations among Turkish population have not been studied previously, we aimed to evaluate the type and frequency of tracheobronchial variations (TBVs) in our bronchoscopy population. In a 3-year period, 1,114 patients underwent flexible bronchoscopy (FB). Among these, 780 (70%) were male. The mean age of the patients was 51.3 +/- 15.1 (range: 17-84) years. In 639 cases, no TBV were detected. A total of 999 TBV were observed in 475 patients. Of all, 71.3% (713) of the total TBV were detected in males. Forty-nine and six-tenths percent (49.6%) of the TBV were observed on the right bronchial system, 49.2% on the left, and 1.2% in the trachea. The five most frequently observed TBV were right lower lobe basal orifice with two subsegments, left lower lobe basal orifice with two subsegments, left upper lobe with three segments, right upper lobe with two segments, and right lower lobe with a subapical segment. In the same lobe bronchus, single variation and two different TBV were seen in 85% and 15% of patients, respectively. Number of TBV increased linearly with the number of lobes involved. The availability and popularity of FB in recent years has led to the increase in identification and reporting of TBV. TBV should be correctly identified and documented. This information is invaluable during follow-up bronchoscopies as well as lung resection.

Diagnostic potential of virtual bronchoscopy: advantages in comparison with axial CT slices, MPR and mIP?

et al. 2000

The aim of this study was to evaluate the diagnostic potential of virtual endoscopy (VE) and to compare it with axial CT slices, multiplanar reconstructions (MPR), minimal intensity projections (mIP), and bronchoscopy in patients diagnosed with bronchogenic carcinoma. Thirty patients underwent a spiral CT. Axial CT images were transferred to an Onyx workstation (Silicon Graphics, Sun Microsystems, Mountain View, Calif.) for performing virtual endoscopy. Accuracy for this procedure was tested by three radiologists on a monitor in comparison with axial CT slices, MPR, mIP, and bronchoscopy concerning the localization and degree of stenoses. Endoluminal tumors were identified by virtual bronchoscopy with no statistically significant difference of localization or grading of stenosis in comparison with bronchoscopy, axial CT slices, MPR and mIP. Axial CT slices, MPR, and mIP showed poorer results with over- or underestimation of stenoses compared with VE and bronchoscopy. Passing of stenoses was only possible with VE in 5 patients. Virtual endoscopy is a non-invasive method for identification of endoluminal tumors and is comparable to real bronchoscopy.
