[The value of sialo-MRI in the study of salivary gland duct pathology].

Usual imaging diagnostic for salivary glands is sialography. Sialography is not stripped of disadvantages and failures. The MRI-sialography is an examination which is carried out without any injection of contrast's product (without catheterization or intravenous injection). It is thus noninvasive and painless. The complete study of salivary gland and its ducts is always possible and could not be blocked by local or loco-regional conditions. It allows exploration of several salivary glands in the same time. We think that the MRI-sialography must find its place in the diagnosis arsenal for salivary pathology in spite of its current handicaps represented by its cost and the difficulty of access to the apparatuses.
