About

Non tumor salivary gland diseases are common and include sialadenitis, sialadenosis, stones, stricture and ductal dilatation, anatomical abnormalities. A radiological examination is required in order to sign the diagnosis, locate precisely the lesions and define the therapeutic strategy. Cone beam computerized tomography (CBCT), because of its accessibility and the possibilities it offers in terms of image processing, is a potential alternative to the conventional sialography and to the MRI sialography, considered as a gold standard procedure. Our comparative study, aims to evaluate the diagnostic performance of the 3D-CBCT sialography compared to MRI sialography, in patients with non tumor ductal salivary diseases.

Full 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.
