3D Imaging of Upper Respiratory Tract

MDCT with volume acquisition enables the 3D reconstruction of complex anatomical regions such as the upper respiratory tract.  With this, we can visualise the paranasal sinuses, the nasopharynx, velopharynx, oropharynx and larynx to great detail.  For example, in patients with nasopharyngeal lesions, the amount of airway narrowing can be easily visualised and interpreted by the physician.  A cine loop of the 3D image can also be made and can be viewed at any workstation. However, it is to be remembered that this is not a replacement for conventional 2D image interpretation, since only air containing regions are visualised here and extramucosal lesions cannot be seen. In the image samples shown below, we can also see the air within middle ear and  mastoids.
