Sialolithiasis is the most common disorder of major salivary glands. Sialogrphy is used to diagnose a blocked salivary gland or duct and has evolved through conventional catheter contrast enhanced radiography to use of digital subtraction radiography, non-enhanced CT, CT sialography and more recently non-invasive MR sialography. In this review we will discuss the technical aspects, procedural failure and complications, benefit and limitations of each modality.

We will describe the technical aspects with images describing normal anatomy in each modality. Multiple cases including sialolithiasis, papillary stenosis, strictures, intraglandular sialectasis and changes related to external compression by tumor will be shown. We will describe the value of lemon juice in MR sialography to stimulate salivation that improves detection of strictures and functional obstruction. Use of interventional sialography procedure for treatment will be reviewed.

We describe the evolution of different techniques including conventional and CT or MR sialography to image salivary ducts and salivary stone diseases.
