Outline of Final Research Achievements

We performed an experimental study for establishing non-invasive image diagnosis of Sjogren’s syndrome (SS). The tendency of an elevation of oxy-hemoglobin after acid stimulation was observed using near-infrared spectrometer in the parotid glands. However, it did not correlate with the degree of gland damage. Moreover, we could not obtain similar results even in the same patients. Motion sensitized driven equilibrium (MSDE) method on MRI could not offer better images. Dynamic curve analysis on the conventional salivary gland scintigraphy showed significant differences between SS and non-SS in every calculated value in the submandibular glands. Therefore, diagnostic criteria on salivary gland scintigraphy should be established based on the values in the submandibular glands.
