Salivary Gland Scan

Parotid Scan

What To Think About

• In North America, a salivary gland scan is rarely done. Most often, a CT scan or magnetic resonance imaging (MRI) is done to look at the salivary glands. An ultrasound scan also may be done to look at the salivary glands. But a salivary scan is the only test that can see how well the salivary glands are working.
• Although a salivary gland scan may be done to evaluate dry mouth caused by Sjögren's syndrome, it usually is not used to diagnose this disease. But a salivary gland scan may be used to diagnose Sjögren's syndrome in a person who has rheumatoid arthritis.
