Charing Cross CT protocol for endoscopic sinus surgery.
The Charing Cross computerized tomography protocol for imaging the paranasal sinuses uses 2 mm thick slices with table increments of 8 mm: 10 to 12 coronal and two axial images are produced. These provide the necessary information for diagnosis of chronic rhinosinusitis and safe endoscopic sinus surgery. The technique is quicker and cheaper than previously described protocols and exposes the lens of the eye to less radiation.
