Age and gender related changes in bronchial tree: a morphometric study with multidedector CT.

Area of Science:

• Radiology
• Anatomy
• Medical Imaging

Background:

• Accurate anatomical measurements of the airway are crucial for clinical interventions.
• Variations in tracheal and bronchial morphology may exist based on demographic factors.

Purpose of the Study:

• To identify gender and age-related differences in tracheal and bronchial dimensions and branching angles.
• To classify trachea types using multi-detector computed tomography (MDCT) imaging.

Main Methods:

• Thoracic MDCT images from 253 patients (aged 0-74 years) were analyzed.
• Measurements included tracheal diameter and cross-sectional area, bronchial diameter and length, and branching angles (subcarinal and interbronchial).
• Trachea morphology was categorized into four types.

Main Results:

• Significant differences in tracheal dimensions were observed between adult males and females.
• Four trachea types were identified: circular (most common), oval, rectangular, and horseshoe-shaped.
• Average subcarinal angles were 34.5° (right) and 38.1° (left); interbronchial angles were 32.4° (right) and 35.2° (left).

Conclusions:

• MDCT is a valuable tool for evaluating the bronchial tree and identifying tracheal variations.
• Findings can aid in procedures like bronchoscopy and the application of tubes and stents.
