DIGITAL SIALOGRAPHY - IMAGING AND INTERVENTION

Digital subtraction imaging (DSI) has been widely used in angiography but less commonly applied to sialography. Over a 3-year period 109 pat ients referred for sialography, 42 males and 67 females with a mean ag e of 44 years (range 8-85 years), were examined using a digital subtra ction imaging technique. 13 patients went on to have an interventional procedure, stone removal or duct dilatation. The role of DSI imaging in sialography and its use in facilitating interventional procedures o n the salivary glands are discussed.
