What is MRI Sialography?
The function of the salivary glands can be evaluated fairly accurately and reliably with an MRI sialography. There is no need for invasive procedures, and the MRI provides salivary gland analysis with information for diagnostics and preoperative planning.
MRI sialography is done when infections, tumours, stones or specific cancerous issues are suspected. The procedure involves an X-ray to determine if any abnormalities are blocking the flow of dye to the gland. A small, flexible tube called a catheter is inserted into the opening of the salivary duct. There is minimal discomfort associated with the procedure.
The procedure doesn’t take longer than 30-120 minutes and is relatively safe.
Why is MRI Sialography done?
- To diagnose sialothiasis (formation of calcium stones which obstructs saliva secretion)
- To detect sialadenitis (infection of the salivary gland)
- To find out autoimmune disease known as sjogren’s syndrome (WBC attacks normal salivary gland)
- To determine the changes in the size of salivary glands due to formation of the tumor/cyst/.
