[99mTc-MDP bone scintigraph in the diagnosis of experimental osteoradionecrosis (ORN) of the jaw].
Controlled studying findings from 62 radionuclide scintigraphic and X-ray photographic examinations of the same stage in the experimental animals indicated. The diagnosis of ORN could hardly be established while bone scintigraphic examination is negative, but it is recommended that ORN mostly exists if scintigraphic result is positive. The grading of bone scanning based on the difference of radionuclide concentration in diseased area offered a reference for treatment. Measuring and calculating both examination pictures, we put forward a method to quantitatively determine the limits of lesions. The facts showed by bone scanning that blood supply was rich and metabolism was vigorous in diseased area of ORN presented a new object for research on fundamental theory.
