ABSTRACT
In the last 30 years, flexible Fibro-optic bronchoscopy has become a major tool for evaluating respiratory disorders in children. Nowadays different imaging modalities for pediatric rachea-bronchial lesions have vastly improved. To identify some potential clinical indications and advantages of Multi-detector Computed Tomography and Virtual Bronchoscopy over Fibro-optic Bronchoscopy in pediatric age group. 25 patients were included in this study 16 males and 9 females, mean age was [25.8 months] suffering from acute or chronic unexplained respiratory symptoms. They subjected to both Multi-detector Computed Tomography and Virtual Bronchoscopy and Fibro-optic Bronchoscopy. This comparative study showed that sensitivity of Multi-detector Computed Tomography and Virtual Bronchoscopy was 63-15% with positive predictive value of 80%, It is sensitive to detect external compression rather than airway malacia. It was sensitive to detect intra luminal obstruction without identifying the pathology which could be more determined by Fibro-optic Bronchoscopy. MDC T- VB may be considered a novel technique for noninvasive evaluation of the tracheobronchial tree in children especially in patients who were not suitable for Fibro-optic Bronchoscopy
