Postintubation tracheal rupture represents a life-threatening condition requiring prompt diagnosis and treatment. Common computed tomography findings of postintubation tracheal rupture include subcutaneous emphysema and pneumomediastinum (imageA). New techniques, including virtual endoscopy, curved planar reformation, and minimum intensity projection, greatly contribute to judging the location and length of tracheal tear.
Virtual endoscopy uses multidetector computed tomography data to display intraluminal geography of the airway in a noninvasive way1  (imageB and C). Curved planar reformation is a type of multiple planar reconstruction accomplished by aligning the long axis of the imaging plane with a specific anatomic structure, such as tracheal (imageD). Minimum intensity projection is a multiplanar slab image generated by displaying only the lowest attenuation value encountered along a ray cast through an object toward viewer’s eye (imageE). The combination of traditional computed tomography with virtual endoscopy, curved planar reformation, and minimum intensity projection could complement each other to display two-dimensional, three-dimensional, and endoluminal structures of the trachea, and provides crucial information for clinical treatment.
