Imaging Study of 3D-CBCT Sialography and MRI Sialography in Non Tumor Salivary Diseases (PIGS)
Prospective, Pilot, Comparative, Monocentric Study of Diagnosis Capabilities of the Three-dimensional Cone-Beam CT Sialography (3D-CBCT Sialography) and MRI Sialography in Non-tumor Salivary Diseases

Detailed Description
Our study focuses on patients over 18 years, with unilateral or bilateral parotid or submandibular salivary symptoms. Each patient included is given a MRI sialography and a 3D-CBCT sialography at a later stage when the acute episode has subsided. Images are archived on the Carestream Picture Archiving Communication System (PACS). Interpretation is achieved after Multi-Planar Reconstruction (MPR), Maximal Intensity Projection (MIP) and three-dimensional rendering. A primary radiological analysis of the two procedures is systematically done by a specialist radiologist for the diagnostic and therapeutic care of the patient. A second radiological data analysis is carried out at the end of the study, by a specialized radiologist, different from the first one, to asses the two radiological examinations.
The primary outcome measure is the capability of the radiological technique to detect a ductal salivary feature. Secondary outcomes include the clinical characteristics of the patients, the diagnostic capabilities in identifying the salivary lesions, their number, their precise location and measurements. A primary side effect in catheterization and dosimetric parameters for the CBCT technique will be systematically recorded.

- Current or suspected pregnancy.
- Patient refusing the examination or the catheterization.
- Salivary symptoms of tumor appearance: Unilateral palpable mass, facial palsy, multiple lymph nodes in parotid and / or pre-auricular and / or neck areas.
- Salivary neoplasm demonstrated by a prior diagnostic testing.
- Patient who underwent head and neck scan in the previous 6 months. Conventional or three dimensional sialography achieved in the previous 6 months.
- Salivary catheterization failure.
