Role of CT Virtual Bronchoscopy In Assessment of Tracheobronchial Lesions In Pediatric Age Group

 Multidetector CT-generated virtual bronchoscopy (VB) is a technique that allows visualisation of the lumen and wall of the trachea and proximal part of the bronchial tree. A dynamic image is produced that resembles what is seen with fibreoptic bronchoscopy (FB).Stridor, wheezing and respiratory distress are the most common indications for imaging of the airway in children. Advanced CT imaging techniques {Postprocessing techniques} such as multiplanar reformatting, volume rendering and virtual bronchoscopy assist in proper planning for treatment.

A major advantage of VB when compared with FB is its noninvasiveness, and can be performed under simple sedation without general anesthesia; so that it can be used easily in children.

It is also fast, reproducible, give adequate airways visualization and clinically insignificant image artifact.

 and can be drawn from CT images, which are often clinically indicated.
