• Bronchial tree
• Multidetector CT
• Tracheal type
• Morphometry

OBJECTIVE: The aims of this study are the identification of differences in the diameter, length, area and branching angles of the trachea and bronchi with gender and age, and the identification of trachea types by using MDCT images.
PATIENTS AND METHODS: The thoracic MDCT images of 253 patients (0-74 years old, 142 male and 111 female) were evaluated. Tracheal diameter, tracheal cross-sectional area, diameter and length of bronchi, and several angles of the bronchial tree [e.g. subcarinal angles (SCA), interbronchial angles (IBA)] were measured.
RESULTS: Average anteroposterior and transverse diameter of the trachea in adult patients were measured as 15.8 +/- 2.9 mm and 17.5 +/- 3.7 mm respectively. Average tracheal cross-sectional areas in adult patients were calculated as 160.7 +/- 41.3 mm(2) in females and as 275.7 +/- 57.3 mm(2) in males. Four types of trachea were identified as circular (68% in adults, 73% in children), oval (13%, 15%), rectangular (11%, 5%) and horseshoe shaped (8%, 7%). The average right and left SCA were calculated as 34.5 degrees +/- 8.1 degrees and 38.1 degrees +/- 8.9 degrees respectively. The average right and left IBA were calculated as 32.4 degrees +/- 7.7 degrees and 35.2 degrees +/- 8.1 degrees respectively.
CONCLUSIONS: The findings of this study may be helpful during bronchoscopy and tube and stent application procedures. MDCT seems to be a convenient technique for the evaluation of the bronchial tree.
