sialography वाक्य

On sialography, it may appear as segments of duct dilation and stenosis.
Further investigations are not typically required, however sialography, ultrasound and computed tomography may all show air in the parotid gland and duct.
Objective evidence of salivary gland involvement is tested through ultrasound examinations, the level of unstimulated whole salivary flow, a parotid sialography or salivary scintigraphy, and autoantibodies against Ro ( SSA ) and / or La ( SSB ) antigens.
